1-2 What is HEX unit?
With many people spending much of their time
indoors at home or work, it is not surprising that
buildings account for a large percentage of all
energy use. This means that there is great scope for
reducing energy use through better-designed
buildings and more efficient heating, cooling and
hot-water systems.
WE NEED TO
Reduce CO2 emissions
Improve energy performance
Ensure that we heat and cool by the most efficient
means possible.

and HEX unit
As a leading manufacturer of energy efficient heat
pump systems, we constantly strive to meet and
exceed the increasing demands placed on our
industry. The drive to reduce energy consumption
and the impact it’s use has on the environment is
crucial and increasingly important to us all. The need
to be more energy conscious and environmentally
responsible has long driven Mitsubishi Electric to
spend huge amounts of resource on researching and
developing the solutions of the future. As market
leaders, at the forefront of the very latest technology,
we pride ourselves in providing high performance
and competitive systems on which you can rely.
Amongst such developments is the advanced heat
pump technology used in Booster unit and HEX unit.

What is Booster unit?
Efficient and technologically advanced, Booster unit takes advantage of proven heat recovery
technology to provide hot water for sanitary use and is one of the most advanced, efficient hot water
systems available today.
TECHNOLOGY
Benefiting from the heat recovery operation of the
CITY MULTI R2 system, Booster unit converts
energy from the air to higher temperatures suitable
for heating water and results in virtually no energy
waste.
HIGH EFFICIENCY
Capable to air condition and supply hot water in a
single system, Booster unit is ideal for use in a
variety of applications. From hotels to restaurants to
gyms, it works perfectly in providing optimum air
environment and hot water to a maximum of 70˚C.

TECHNOLOGY
HEX unit works perfectly to provide heating and
cooling to water fan coil units, panel heaters, or
under floor heating systems. It benefits from the
high-efficient operation of our CITY MULTI and heat
recovery operation when used with R2 system.
FEATURES
HEX unit offers 45˚C in heating and down to 8˚C in
cooling, making it suitable for residential properties,
offices or hotels, providing an optimal environment
while benefiting from reduced running costs and
lessening the impact on our environment.
