More Energy Saving
The heat recovery technology improves cooling efficiency, reduces
power consumption, and extends the service life of a unit. The
total heat recovery technology recovers all condensate heat, saves
power consumed by the fan of the heat exchanger at the air side,
and reduces energy consumption by more than 15%.
One Unit for Three Purposes
One unit can be used for three purposes: cooling, heating, and free
hot water. The unit can provide hot water with a temperature up to
65°C to meet guest house showering, kitchen cleaning, and factory
hot water consumption requirements, thus saving investment in hot
water equipment.
Less CO2 and More Environment Friendly
EK air conditioners feature a leading-edge total heat recovery
technology to use waste heat, greatly save energy, and effectively
mitigate the heat island effect in cities due to waste heat
dissipation.
Easy Installation
The unit can be easily installed outside and requires no dedicated
equipment room or operator. Free hot water is available as long as
you connect the hot water pipes.
