Coupling & Connection

Connection to the pipework should be diagonal corners of the
panels or groups of panels, to ensure an even flow through the
pipe system an allowance must be made in the
interconnecting pipework for venting and draining if this is not
designed into the panel pipe system.

Thermal Expansion

The panels will accommodate their own pipe system
expansion but allowance should be made in the
interconnecting pipework. The design of the installation will
allow for expansion of the heated panels in relation to other
parts of the building structure and either a small gap or cover
strip is provided to accommodate the movement. The design
of the system must give turbulent flow in the pipes.

Testing Protocols

Testing Protocols

All pipework manufactured on Frengerwarm panels are
pressure tested to 7 bar.

Thermal Insulation

Frengerwam is supplied as standard with 60mm thick Mineral
Wool blankets backed with Class ‘O’ reinforced heat reflecting
metal foil.

Panels

Material depends on the application.
Aluminium - 1.5 - 2.0mm thich NS3 / H4 aluminium sheet.
The radiating panel can be supplied with edges formed to suit
the individual application. Non radiating ‘in fill’ panels can be
supplied to form a continuous covering for the wall, column or
ceiling. Access panels with ‘secret’ fixings are a standard part
of the range.

Pipework attachment system

Aluminium Frengerwarm - the copper tube coil is inserted
within a patented extruded aluminium heat carrier. The
aluminium heat carrier is bonded to the panel. Heat transfer
paste is used at all interfaces for both types of Frengerwarm.

106

Fixing

Fixing

An installation service is provided by Frenger. However, supply
only can be accommodated. The following notes are provided
so that during design of the heating system for the building,
due account can be taken of the various requirements for
fixing Frengerwarm.
Frengerwarm is wall, column or ceiling mounted and
individually tailored for the installation.

Attachment

As each Frengerwarm installation is individually designed, the
means of attachment will be engineered for the specific
situation. Frengerwarm may therefore be attached to any
substantial building structure.

Pipework

Connection to the pipework should be at diagonal corners of
the panels or groups of panels, to ensure an even flow through
the pipe system an allowance must be made in the
interconnecting pipework for venting and draining if this is not
designed into the panel pipe system.
Expansion: The panels will accommodate their own pipe
system expansion buy allowance should be made in the
interconnecting pipework. The design of the installation will
allow for expansion of the heated panels in relation to other
parts of the building structure and either a small gap or cover
strip is provided to accommodate the movement. The design
of the system must give turbulent flow in the pipes.

Installation of panels and insulation

Frengerwarm is supplied as completed panels with the
pipework and insulation attached, it is therefore important to
protect the surface of the panel from damage during
construction or to schedule the fixing of Frengerwarm as one
of the final constructin operations. All the necessary water
piping can be installed at an earlier date as this is normally
hidden behind the Frengerwarm panels.

107

Optional Extras

The following optional extras are available for Frengerwarm.

Panels

Unheated ‘dummy’ panels and cover strips. A range of
extruded aluminium edge and tee trims. Radius Edges
(Bullnosed).

Pipework

15MM OD copper, to EN12449 / EN12735-2 Final flow and
return connections to suit customer’s requirements.
Thermostatic controls and air vents.

Colours

RAL 9010 Matt White powdercoat as standard. However other
RAL colours are available.

Operations &
maintenance

Frengerwam is incorporated into a building’s heating / cooling
system and is completely trouble free, however a few simple
precautions should be taken and inspections made during
start up and maintenance.

Operations

There will be no problems when starting up the system on hot
or cold water if the drain valves are shut and any air has been
vented from the system.

Any thermostatic controls on the panels should be set to the
required temperature.

Maintenance

Apart from cleaning any strainers no maintenance should be
required on the pipework system. Any descaling of pipework
should be carried out in the same way as for normal heating
systems,

Operation of the thermostatic controls should be checked
periodically.

During a period when the heating / cooling system is not in use
the opportunity should be taken to inspect any damaged
panels. Damage to a panel may cause the water pipes to
become detached and hence reduce their heating effect.

Electric Heating

Radiant Heaters Surface Mounted Air Curtain
EnergoCassette Radiant Heater
Electric Radiant Heating is a highly effective method of heating EnergoStrip Radiant Heater
a room. Electric Heating Panels heat all of the rooms
surfaces (desks, floor, etc.), which in turn heat up the air within
a room. Consequently, electric radiant heating panels afford an
extremely comfortable indoor environment, where there is
little risk of the person feeling too cold under the table or too
hot on the head. Furthermore, electric radiant heating focuses
on the areas where heating is most required – the coolest
items in the room (usually the external walls or windows).
Unlike convective heating, an increase in ceiling height does
not significantly increase the amount of heating required.

Product benefits can be summarised as follows:

Immediate heat.
Discreet.
Mounting heights up to 40m.
Recessed mounting option.
Ceiling mounting option.

Air Curtains

Frenger’s range of Air Curtains create an air barrier, which
helps to prevent cold draughts thus creating a comfortable
indoor climate. Energy losses through openings are reduced,
which means considerable savings.

When the doors are closed, the Air Curtains will contribute
towards the heating around the entrance area if required.
The heated air from the air curtains will also help to dry any
water / sleet dragged in to an entrance, as such assisting in
creating a safer environment.

Although our Air Curtains emit warm air, the main purpose
of an Air Curtain is not to provide general heating in a space
but to balance temperature differentials and maintain these
differentials by using a pressurised stream of air.

Product benefits can be summarised as follows:

Compact.
Low noise.
Suitable for doors of almost any width.
Suitable for doors heights up to 4m.
Ambient, electric or water heated designs.

EnergoStrip Introduction

EnergoStrip Radiant Heater The EnergoStrip is an electric radiant heater that will supply
gentle, even and comfortable heat in various applications
from small stores or bathrooms to large industrial units. The
heaters can be used to provide general heating, or to raise the
temperature in certain areas (spot heating).

The heat is concentrated in the occupied area, thus minimising
energy losses through the stratification of heated air. The
system is simple and inexpensive to install and maintenance
free.

EnrgoStrip emits a gentle, pleasant radiant heat (infrablack,
long wave), not to be confused with high - temperature
shortwave infrared heat. The product is consequently ideal to

*Output based on a Water Flow / Return Temperature of 82 / 71°C with an air entering temperature of 20°C.
**Sound pressure levels (dBA) at 3m, as given in our brochure, are for a single air curtain mounted at its maximum mounting height, operating in a room
with average acoustic characteristics as defined in CIBSE Guide B5 (reverberation time 0.7s) and a room size equivalent to 8 air changes per hour (ac/h).
Care needs to be taken when selecting air curtains for an installation as noise levels can be several dB higher if the mounting height is reduced, if the
room is more “live” (i.e. hard surfaces, no furnishings or absorbent materials), if the room is smaller than 8 ac / h equivalent or a combination of these
factors. Noise levels will also increase if more than one air curtain is installed at the same doorway (e.g. + 3dBA for 2 equal point sources: direct field).

*Output based on a Water Flow / Return Temperature of 82 / 71°C with an air entering temperature of 20°C.
**Sound pressure levels (dBA) at 3m, as given in our brochure, are for a single air curtain mounted at its maximum mounting height, operating in a room
with average acoustic characteristics as defined in CIBSE Guide B5 (reverberation time 0.7s) and a room size equivalent to 8 air changes per hour (ac/h).
Care needs to be taken when selecting air curtains for an installation as noise levels can be several dB higher if the mounting height is reduced, if the
room is more “live” (i.e. hard surfaces, no furnishings or absorbent materials), if the room is smaller than 8 ac / h equivalent or a combination of these
factors. Noise levels will also increase if more than one air curtain is installed at the same doorway (e.g. + 3dBA for 2 equal point sources: direct field).

Acoustic Lighting and Heating Rafts

Frengers Acoustic Lighting and Heating Rafts, otherwise Heating Raft Type 1
known as Multi Service Radiant Panels (MSRP’s) consist Figure 1
essentially of a free hanging radiant heating panel coupled
with other services such as:-

Lighting.
Acoustic Sound absorbing materials.
Apertures for sprinkler heads.
Compartment trunking for other electrical services.
Apertures for PA and VA speakers.
Lighting Control, PIR and Photocells.

Radiant Heating

The radiant heating element is the same technology as utilised
for Frenger’s tried and tested Modula panels.

The panel is constructed from zinc coated steel which is
perforated and folded to the project specific requirements
before being polyester powder coat finished to any RAL
colour as required, (RAL 9010 is standard).

The panel utilises Frenger’s optimised extruded aluminium
heat exchanges and seamless copper tube heating elements.

Lighting

Virtually any type of lighting solution can be accommodated
by Frenger’s MSRP and all lighting is manufactured in house
and bespoke to the project solution. Direct only, indirect only,
combination of direct and indirect lighting from either the
same light source or different sources can be accommodated.

T5 florescent or LED light sources, aluminium louvers, micro
lens optics, opal acrylic or even extruded acrylics for
continuous / seamless lighting can be accommodated.

All lighting is designed in house using lighting software design
packages and the prototyped and photometered in Frenger’s
in house Photometric Laboratory and Integration Chamber
for L.O.R (Light Output Ratios). Frenger convert to Lumdat
files and produce lighting calculations for the space
requirement using Relux / Dilux for compliance to CIBSE
Lighting Guides LG3/7.

Acoustic Sound Absorbing Materials

The perforated areas of the radiant panel are covered with
black tissue faced insulating material with a foil backing
effectively sandwiched in the middle of two layers of acoustic
insulating material, the top layer of which has black tissue
acoustic material face upwards as shown in the figure 1.

Frenger’s have their own in house sound laboratory and also
make use of third party acoustic testing for verifications.

Note: Acoustic Absorption Area (m²) figures detailed below are per linear m of MSRP, hence the
absorption area’s should be multiplied by the chosen MSRP length. Data based upon independent
testing conducted by SRL (Sound Research Laboratories) Ref. C/21760/R01 to BS EN ISO
354:2000.
