Frenger Systems is a world-renowned specialist manufacturer
of space conditioning products for indoor climate /
environments. Frenger has extensive experience dating back
some 80 years and is at the forefront of the design,
development and manufacture of water driven cooling and
heating technologies. Over the years Frenger has earned an
enviable reputation as a dependable supply partner capable
of developing effective space conditioning solutions for the
most complex of projects.

In 1962 Frenger designed, supplied and installed the
“World’s Largest Radiant Chilled Ceiling” system which
was revolutionary at the time. This consisted of 175,000
square meters of radiant chilled ceiling over the 27 storeys
of the Shell Oil headquarters, situated on the river Thames
in London. The Thames water was used via secondary heat
exchangers to cool the water that circulated on a closed
circuit around the ceilings within the building. This building
was also the first fully sealed air conditioned building in
Europe. This installation is still operating after some 50 years
and is a testament to the integrity of the product and to
Frenger’s design capabilities.

Frenger also pioneered with the supply of Chilled Beam
and ceiling technology to Australia in 2003 and was for

the first ever building to be awarded a 5 star energy
rating. The building was called “The Bond”, situated in

Sydney and developed by Bovis Lend Lease (BLL); whom
are now known as Lend Lease.

BLL spent considerable time researching Chilled Beam and
Ceiling Technology worldwide and undertook a great amount
of due diligence before selecting a Chilled Beam supplier for their
then highly confidential building (“The Bond”, 30 Hickson Road,
Sydney). Many of BLL’s competition thought that it
was not possible to gain a 5 star energy rating and as such
BLL knew that the stakes were extremely high and much
depended upon their success. Frenger were then chose by
BLL to play an integral part of what transpired to be a
successful process and the building is still, some 10 years
later, functioning well and coping with external temperatures
in the region of 40°C for some parts of the year.

Since 2003 Frenger has supplied Chilled Beam
technology to many 5 star and even 6 star energy rated
buildings more recently in Australasia, some of these can
be seen on pages 149 to 151 of this Brochure under the title of
“Project References”.

In addition to Frenger providing the first Chilled Ceiling in
1962 and providing the first ever 5 star energy rated building
in 2003, Frenger pioneered with Multi Service Chilled Beams
(“MSCB’s”) in the UK and having designed, supplied and
often installed many successful MSCB projects. Frenger were
selected by Blyth and Blyth for the £160 Million refurbishment
of London & Regionals “55 Baker Street” building which
involved HBG Construction (now known as BAM Construction)
amalgamating 3 separate buildings into one enormous building
with 2 central atriums and two internal streets.

5

Frenger designed, Climactic Tested (full scale laboratory
mock up), manufactured and installed these MSCB’s in
2007 which represented circa 7 million GBP order value
to Frenger. This was and still is the world’s largest MSCB
installation. HBG’s annual award for Best Sub-Contractor
was also awarded to Frenger and Frenger also gained various
letters of commendation from the Client, the Consulting
Engineers and the Main Contractor regards their performance
of their involvement with the 160 million GBP refurbishment
project. Details of this and other major projects by Frenger
can be found on page 148 of this Brochure under the heading
“Large Project Experience”.

The reason as to why Frenger are chosen for such important
high profile and complex projects for the space conditioning /
indoor climate is because Frenger:

Have the highest performing products on the market.
Excellent product quality.
Always deliver on what is promised and never over state
/ over sell.
Have everything in-house to substantiate all aspects of
the indoor environment.
Manufacture as many key items in-house as possible to
keep full control.
Take ownership to deliver what is required, on time, on
budget and to the correct specification.

Frenger employs professionally qualified Mechanical
Engineers, Electrical Engineers, Lighting Designers,
Building Services Engineers and Project Managers to
give customers an unrivalled level of in house expertise
for Chilled Beam and Multiservice Chilled Beam (MSCB)
technologies. Frenger builds sound business relationships
with clients and has won many accolades to this extent, which
has warranted Frenger a justifiable reputation for delivering
complex projects on time, within budget and to specification,
every time. All aspects of the business are accredited to
BS EN ISO9001:2008 and are regularly audited by the
British Standards Institution (BSI).

Due to Frenger’s continuing success, the shareholders of its
parent company, the FTF Group, provided Frenger in 2009
with one of their fully owned multi million GBP buildings for
fit out as a new Technical Facility. The building is situated in
the East Midlands, UK and holds a prominent position on the
prestigious Pride Park corporate business centre. Frenger
have equipped this building to support all technical aspects of
the companies’ world wide operations.

The new headquarters are fully space conditioned with various
different types of Chilled Beam, MSCB and Chilled Ceiling
technologies, each controlled by a full building management
system (BMS) which can demonstrate exactly how well each
chilled system is functioning and their efficiencies. This
building also houses Frenger’s:

Specialist manufacturing
State-of-the-art Climatic Test facilities
Photometric test laboratories
Acoustic laboratory
Thermal imaging capabilities
Lighting design capabilities
2D & 3D CAD operations
Computational fluid dynamics and
Solidworks.

CHleimadaeter Teitlseting Facility

Frenger has three climatic test laboratories located at it’s
technical centre which is located at the prestigious Pride Park,
Derby, England.

These purpose designed and built laboratories have nominal
internal dimensions of 6.3m (L) x 5.7m (W) x 3.2m (H) and
each environmental chamber includes its own thermal wall
so that both core and perimeter zones can be physically
modelled in any of the rigs.

All three environmental chambers are fixed in size however 1 of 3 climatic test laboratories
the fitment of partition walling and false ceilings can be
positioned to match the physical constraints of a project
specific installation. Frenger also have in-house thermal
imaging capabilities.

Catalogue Data - Standard Product

All Frenger’s products are designed by Frenger’s in-house
Research and Development (R & D) department. Once any
new product is ready for mass production these are tested
in-house to the following British Standards for Catalogue
Data to be collated / published:

BS EN 14240:2004 – Ventilation for buildings – Chilled
ceilings – Testing and rating.

– Ventilation for buildings – Chilled
BS EN 14518:2005 beams – Testing and rating of
passive chilled beams.

– Ventilation in buildings – Chilled

ISO 7730



In addition to the above in-house comprehensive testing which
utilises state of the art equipment and BSRIA calibrated
instrumentation to reduce the amount of uncertainty to an
accuracy of + / - 2.5%, Frenger also subscribe to third part
Validation Testing by Eurovent.

Eurovent certification testing is only for performance and
takes no account of the indoor environment, whereas all
Frenger testing and published catalogue data is compliant
to ISO 7730, ergonomics of the indoor environment to ensure
that occupancy comfort is maintained to the highest of
standards.

Project Specific Testing

Project specific mock-up testing is a valuable tool which
allows the Client to fully asses the proposed system and
determine the resulting indoor quality and comfort conditions;
the physical modeling is achieved by installing a full scale
representation of a building zone complete with internal &
external heat gains (Lighting, Small Power, Occupancy &
Solar Gains).

The installed mock-up enables the client to verify the following:

Product performance under project specific conditions.
Spatial air temperature distribution.
Spatial air velocities.
Experience thermal comfort.
Thermal imaging (still images and video footage).
Project specific aesthetics.
Experience lighting levels (where relevant).
Investigate the specific design and allow the system to be
enhanced.

The project-specific installation and test is normally
conducted to verify:

Product capacity under design conditions.
Comfort levels - Air temperature distribution.
- Thermal stratification.
- Draught risk.
- Radiant temperature analysis.
Smoke test video illustrating air movement.

AHceoaudsetricTTitelesting Facility

The Acoustic Test Room at Frenger System’s Technical
Facility is a hemi-anechoic chamber which utilises sound
absorbing acoustic foam material in the shape of wedges to
provide an echo free zone for acoustic measurement; the
height of the acoustic foam wedges has a direct relationship
with the maximum absorption frequency, hence Frenger
Systems had the wedges specifically designed to optimise the
sound absorption at the peak frequency normally found with
our active chilled beam products.
The use of acoustic absorbing material within the test room
provides the simulation of a quiet open space without
“reflections” which helps to ensure sound measurements from
the sound source are accurate, in addition the acoustic
material also helps reduce external noise entering the test
room meaning that relatively low levels of sound can be
accurately measured.
The acoustic facilities allow Frenger Systems to provide
express in-house sound evaluation so that all products, even
project specific designs can be assessed and optimised.
To ensure accuracy Frenger Systems only use Class 1
measurement equipment which allows sound level
measurements to be taken at 11 different octave bands
between 16 Hz to 16 kHz, with A, C and Z (un-weighted)
simultaneous weightings.
In addition to the above, Frenger Systems also send their new
products for specialist third party Acoustic Testing. The results
of which are very close and within measurement tolerances to
that of Frenger Systems in-house measurement of sound.

Photometric Testing Facility

The Photometric test laboratories at Frenger Systems are
used to evaluate the performance of luminaires. To measure
the performance, it is necessary to obtain values of light
intensity distribution from the luminaire. These light intensity
distributions are used to mathematically model the lighting
distribution envelope of a particular luminaire. This distribution
along with the luminaires efficacy allows for the generation
of a digital distribution that is the basis of the usual
industry standard electronic file format. In order to assess the
efficacy of the luminaire it is a requirement to compare the
performance of the luminaire against either a calibrated light
source for absolute output or against the “bare” light source for
a relative performance ratio.

The industry uses both methods. Generally absolute lumen
outputs are used for solid state lighting sources and relative
lighting output ratios (LOR) are used for the more traditional
sources. Where the LOR method is chosen then published
Lamp manufacturer’s data is used to calculate actual lighting
levels in a scheme.

The intensity distribution is obtained by the use of a
Goniophotometer to measure the intensity of light emitted
from the surface of the fitting at pre-determined angles. The
light intensity is measured using either a photometer with a
corrective spectral response filter to match the CIE standard
observer curves or our spectrometer for LED sources.

Luminaire outputs are measured using our integrating sphere
for smaller luminaires or our large integrator room for large
fittings and Multi Service Chilled Beams. For both methods
we can use traceable calibrated radiant flux standards for
absolute comparisons.

All tests use appropriate equipment to measure and control
the characteristics of the luminaire and include air temperature
measurements, luminaire supply voltage, luminaire current
and power. Thermal characteristics of luminaire components
can be recorded during the testing process as required.

A full test report is compiled and supplied in “locked” PDF
format. Data is collected and correlated using applicable
software and is presented electronically to suit, usually in
Eulumdat, CIBSE TM14 or IESN standard file format.

Frenger conduct photometric tests in accordance with CIE
127:2007 and BS EN 13032-1 and sound engineering practice
as applicable. During the course of these tests suitable
temperature measurements of parts of LED’s can be recorded.
These recorded and plotted temperature distributions can
be used to provide feedback and help optimise the light
output of solid state light source based on luminaires which are
often found to be sensitive to junction temperatures.

X-Wing® - “Radiant”
Passive Chilled Beam

Frenger has extensive experience in the design and 125mm Radiant
manufacturing of “Radiant” / Convective Passive Chilled Beam X-Wing® (Radiant Chilled Beam) Beam
solutions; providing discreet and cost-effective space
conditioning to commercial, educational and healthcare Radiant Chilled Beam Air
environments. Over the past 20 years, products have been Velocity
supplied to major projects throughout Europe, and as far Convective Only Fincoil Battery
afield as Australia. Frenger’s “Radiant” / Convective (m/s)

This type of solution does not create any noise or draughts in Velocity
office environments, and improve both the comfort and is
reported to increase the productivity of the occupants. The (m/s)
system ensures a very low degree of air movement below 0.34

When cold water passes through our “Radiant” / Convective 0.10
Passive Chilled Beam the warm room air is cooled against 0.06
the surfaces. This chilled air, which then becomes heavier, 0.02
then streams through the punched louvres in the radiant beam
and percolates through the small ceiling perforations
into space below (when concealed). In this way air is circulated
within the room, with warm air from the room space being
continually replaced by cooled air.

In addition to this convective process, the cold surfaces of
the beam also absorb heat radiation from the building
occupants and the warmer surrounding surfaces. The radiant
quotient is approximately 40% of the total cooling effect
(the other 60% of cooling being generated by the
convective cooling effect described above). The ability of
our “Radiant” / Convective Passive Chilled Beam to also cool
by radiant absorption means that, when compared to a finned
tube battery, our beam can deliver 40% more cooling without
any additional risk of draught.

In addition to the convective heat transfer common to all
passive chilled beams, the radiant effect of the products also
cools the metal ceiling system (secondary radiation), which
in turn re-radiates this cooling effect into the room. The
radiant effect of the beam also provides a more
comfortable environment for the building occupants and
even less chance of any draughts (draught risk rating is
reduced). The system provides the comfort and aesthetic
benefits of radiant chilled ceilings at a significantly lower cost
and whilst maintaining the higher cooling capacities associated
with chilled beam installations.

Composition and manufacture

Frenger’s “Radiant” / Convective Passive Chilled Beams are
constructed from coiled copper which is formed into serpentine
coils utilising full CNC, state-of-the-art automated decoiling
and bending machines. This process eliminates the risk
of any leaks as there are no joints in the copper water
circuit of the product. The aluminium radiant “wings” which
make up the cooling surface are mechanically fixed around
the copper tube serpentine one piece coil in which the cold
water is transported to provide 100% encapsulation of the
waterways for optimum transfer of energy from the radiant
wings to the copper waterways. Both the copper tubing
and aluminium wings are 100% recyclable.

Dimensions

Frenger “Radiant” / Convective Passive Chilled Beams are
compact and versatile in the way that they can be mounted

1) Performance calculations are based upon normal clean potable water; it is the system engineer’s responsibility to allow for any

reduction in cooling or heating performance due to additives that may reduce the water systems heat transfer coefficient.

2) Pressure drop calculations are based upon CIBSE guides using clean potable water and exclude any additional losses
associated with entry / exit losses, pipe fouling or changes in water quality; it is the system engineer’s responsibility to use
good engineering practice.

“Performance Data” will then be automatically be calculated.
Likewise “Dimensional Data” will be also automatically
calculated.
Finally, the “Design Check” should read “OK” in green, or detail

Active Chilled Beam Principles

Frenger manufactures and supplies a range of active
chilled beams with the highest performance curves on
the market. Frenger draw upon high performance
technologies and patent pending / registered design features
to deliver efficient cooling to commercial, educational and
healthcare environments.

Efficient and quiet space conditioning

Frenger’s patent pending battery angles, air chamber
geometry and unique burst nozzle strip enables their Active
Chilled Beams to deliver unrivalled levels of cooling capacity
with a given air volume whilst ensuring that the reconditioned
air is delivered into the space in a controlled manner that best
suits the application. The units are so efficient that they
can provide cooling in excess of 250 W / m with fresh air
supply of as little as 1 litre / s / m².

Units are designed to integrate into suspended ceiling 208mm 227 - 267mm
systems. They fit easily into the most common ceiling designs
and have removable underplates that can be perforated to Ultima® Two way discharge
match perforated metal ceilings where required or to best 133mm
compliment mineral fibre or plasterboard ceilings. These
removable underplates provide access for maintenance, Compact® Two way discharge
although maintenance is minimal given that there are no
moving parts.

Frenger’s Active beams are also designed to ensure low noise
levels. They incorporate a patented air chamber burst nozzle
strip technology which delivers cool air to the room very
quietly, and makes them suitable for discreet installation in
hotels, offices, hospitals, schools and banks. Air delivery can
be accurately controlled so that air velocities do not
exceed 0.25 m / s, ensuring compliance with ISO 7730
by use of discrete air deflector vanes mounted as part of the
patent pending and registered designed air chambers. Beams
can be supplied with factory fitted condensation sensors.

Operation

An active beam is esentially a water driven ceiling-mounted
induction unit. It uses a supply of fresh ventilation air to induce
warm room air (recirculated air) through the unit’s cooling
fincoil battery. The Frenger beam is able to induce and
condition 4-5 times as much room air as fresh air supplied.
Conditioned air is then quietly reintroduced into the room,
entraining to the ceiling rather than being jetted out directly
below the beam, thanks to patent pending air chamber design
that produces a Coanda effect. The patent pending nozzle
technology also allows the Company to determine and
factory-set the airflow dispersion characteristics of each unit.
Beams can deliver a cooling capacity in excess of
1000 W / m.

Composition and manufacture

Air is cooled as it passes through a fin coil battery, which Eco™ Two way discharge
comprises aluminium fins with copper tubes through which
water passes. The heat of the room is taken in through the
aluminium fins, and transferred into the water circuit through
the copper tube and transported away via the circulating
chilled water back to a central chiller unit. Active chilled beams
have no moving parts, and as such maintenance costs are
minimal.

Dimensions 230mm
Halo® 360 degree discharge pattern
The Frenger units have side-mounted air chambers that
facilitate high cooling in very compact dimensions. Our slim 340mm
line beams range which can operate with up to 50 ltrs / sec
and is just 133mm deep, whereas our High Output beam Cornice™ One way ceiling discharge
range which can operate with up to 80 ltrs/sec and is just
208mm deep. Both of which can achieve 1000 W / m total
cooling.

Benefits of active chilled beams

Units can deliver cooling, heating, fresh air and lighting.
A range of beams with 1-way, 2-way and 360 Degree air
discharge.
No moving parts equates to reduced maintenance costs.
Capital costs now comparable and / or less than traditional
air conditioning systems.
Improved efficiencies translate to lower running costs.
Can be installed in shallow ceiling voids.
Units can deliver cooling capacities in excess of 200W / m.

Frenger’s unique features

All recirculated air is induced through the removable
underplate and consequently there is no need for a return
air path via the ceiling void.
Advanced Patent Pending battery angle technology
delivers induction ratios of 5:1, enabling effective cooling at
supply air rates as low as 1litre / s / m².
Patent Pending burst nozzle strips design result in quiet
operation.
Advanced air chamber design creates a Coanda effect, with
air entraining to the ceiling for improved occupancy comfort
levels.
Registered designs for concealed air discharge vanes
provide “fan shaped distribution” technology as standard
which reduces the risk of high air speeds in the occupied
zone providing higher levels of thermal comfort.
Air delivery can be accurately controlled such that velocities
do not exceed the 0.25m / s as required by ISO 730.

Air Distribution

Frenger’s range of active chilled beams have been
specifically designed to deliver air into the space in a controlled
and predictable manner. All beams create a Coanda effect
in the unit which encourages the supplied air to entrain to
the ceiling or soffit, furthermore, units can be
manufactured with varying throw characteristics (short,
medium or long) and even with different air delivery
characteristics from either side of the unit, or at one end
of a unit if required.

Air distribution and comfort levels are determined by many
factors; supply air temperature, air volume, air pressure, air
direction and entrainment (Coanda effect) and beam spacing.
Extensive laboratory tests have been undertaken by Frenger
in their inhouse state-of-the-art climatic test laboratories, to
develop a library of empirical data presented in the form of
scatter diagrams, which enables the designer to select the
most appropriate product configuration for any given condition.

Maintenance

All units are provided with simple access to the cooling battery
through the removable underplate - there is no requirement to
access the ceiling void for maintenance or cleaning.

Air Cooling Effect

Cooling effect supplied in the ventilation air [W] Air cooling effect as a function of airflow. For example,

1. Start by calculating the required cooling effect that has if the air flow is 30 l/s and the under-temperature of
to be supplied to the room in order to provide a certain
temperature. the supply air is ∆t ra = 8k, the cooling effect from the
graph is 290W.
2. Calculate any cooling effect that is provided by the
ventilation air.

3. The remaining cooling effect has to be supplied by the
beam.

Formula for air cooling effect: P=m x Cp x ∆t
Where:
m = mass flow [kg/s]
Cp = specific heat capacity [J/(kg-K)]
qp = air flow [l/s]
∆t = the difference between the temperature of the room and

the temperature of the supply air [K]
It is usually m x Cp ≈ qp x 1.2

Frenger’s calculation programme for Compact is extremely
user friendly.

Simply select from the drop down menu the “Air Connection”
configuration. Air volumes in excess of 40 ltrs / sec and up to
50 ltrs / sec should be 2 x 80 diameter.

“Manifold types” can be changed in the drop down menu for
increased waterside cooling effect, however attention needs
to be taken regarding resultant pressure drops (hydraulic
resistance). If pressure drops need reducing, choose a higher
numbered manifold (C5 being the highest and C2 being the
lowest).

Active Chilled Beam Calculation Tool “Discharge Throw” can be S (short), M (medium) or L (long).

Hygiene

It is important to clean the product to ensure that it looks its
best, that it operates at an optimum level, that it will last as
long as possible and that it does not present an infection
control risk. During development of the Frenger
Eco - Healthcare chilled beam the ease of cleaning was of the
highest priority.

The underplate to Eco - Healthcare™ is simple to lower or
totally remove. The underplate hooks onto a patent pending
extruded aluminiu section which is part of the fin coil battery.
When “joggled” off the extrusion the underplate can hang on
the factory fitted safety cords.

When the underplate is either hanging down on the safety
cords or totally removed, the fin coil battery is accessible
from below. The fin coil battery can be easily lowered by the
removal of four retaining screws (poze headed screwdriver) to
enable 60mm clearance behind the fin coil battery and ample
clearance to both sides where air passes.
