the manufacturing process.

Explaining the cycle, he

says that right from the raw

“We employ robots not just because of the

industry, Charles Khairallah,
President, Robotics Design,
says, the evolution of robotics
is pushing service providers
to ideate and develop even
better technologies. He says, “The
acceptance of robotic technology
in the HVAC industry is growing
worldwide. The market is shifting to
robotics, and robots will be catalysts
in the cleaning and maintenance
industry. This is why it is important to
put forward high-quality robots to help
build trust between the robot and
the end-user.”

Further explaining the role
of robots in the maintenance
side of HVAC, Khairallah says
that even today, in a significant

still archaic, and manual cleaning is
a mundane and highly time-consuming
task, which has led to disastrous accidents,
unexpected overhead costs, and can
also be extremely detrimental to a duct-

robots are a clear solution to occupational

which will tackle air pollution effects,
and be a great benefit for the entire

Speaking with a sense of understated
pride, Dr Caussy further says: “When
I first spoke about using a robot to
clean air to a bunch of scientists, they
thought I was crazy. But today, I have
demonstrated that I could bring a

change in the current system through
this invention.”

He adds that this invention
not just cleans the air, but
also increases the overall

performance of the HVAC system,
while reducing the energy
consumption.

Explaining the key features
behind the robot, Dr Caussy says:
“The robot is fitted with neuro-
inspired artificial intelligence.
While detecting polluted air, the
robot sucks in the air, purifies it
through H13+filters and emits
it into the room. While doing so,
it can remove 99.95% of the air
pollutants, bacteria, viruses and
odours, without the use of chemicals.”
The robot, he adds, can also share
data related to IAQ and HVAC systems
with maintenance companies. By
improving the IAQ, and the efficiency of
the HVAC systems, the health and the
productivity of the occupants are also
improved.

*

HIGHEST CAPACITY

The MD Everest Cooling Tower offers greater than 85% more cooling
capacity per cell compared with other preassembled counterflow
cooling towers. At 2500 tons, the MD Everest Cooling Tower is an ideal
one-to-one match for some of the largest chillers.

INSTALLATION SAVINGS

The MD Everest Cooling Tower’s design minimizes piping and electrical
connections to reduce installation costs.

HIGHEST VALUE

The MD Everest Cooling Tower offers significant advantages compared
with other counterflow towers, including unmatched cooling capacity,
energy efficiency, fewer components, and lower maintenance costs.

LOWER DRIFT RATE

The MD Everest Cooling Tower achieves a low drift rate, down to 0.0005
percent of circulating water flow, so less water escapes the tower.

FASTER DELIVERY AND INSTALLATION

Compared with field-erected alternatives, the MD Everest Cooling
Tower delivers 60% sooner and installs 80% faster.

elements, such as materials and the kind of
technology used while building the cooling
towers.

KEY DRIVERS

In the GCC region, cooling towers are
exposed to corrosive environments;
therefore, material selection is a crucial
component. One of the key technology
elements introduced to the market is
Pultruded Fibreglass Reinforced Polyester
(PFRP), says Imran Ali, Managing Director,
HVAC & Power Solutions.

“PFRP material for cooling towers is most
preferred in this region, for it has many
advantages over the conventional materials
of construction, such as concrete, wood
and steel,” Imran Ali says. “The material
possesses exceptional chemical and
corrosion resistance to acid, salt and sand. It
is also resistant to seawater, brackish water,
treated sewage water and others.”

While the selection of construction
materials is critical to driving energy
efficiency, the other technical considerations
that need focus are the drift eliminators,
says Saad Ali, General Manager, Middle
East & Africa, SPX Cooling Technologies.
“Considering that water efficiency is of
paramount importance, drift eliminators
play a key role in trapping large water
droplets and [preventing] mist from
escaping the cooling tower, which reduces
the wastage of water,” he says.

Sharing a similar view, Dumont Swezy,
Vice President – Business Development,
International Cooling Tower, says: “Drift
eliminators play a crucial role in reducing
wastage of water, because they can achieve
the lowest measurable drift rate, which can
go as low as 0.0005% of circulating water
flow. But there have also been significant
advancements made in the heat transfer
media component. We now see a greater
heat rejection and tolerances towards water
