CHILLERS AND HEAT PUMPS
INDEX HYDRONICS AND ROOFTOPS
An air cooled chiller uses ambient air to cool and condense the hot refrigerant in the condenser.
Advantages:
· Simple design (no need for cooling systems such as cooling towers), low installation costs
· Small footprint, easier to maintain and manage than water cooled systems
· Reduced initial cost

Compressors and refrigerants combination
Scroll compressors.
Scroll compressors have
excellent low vibration and low
noise properties.
Compact in size and suitable for
designs where space is

In-house manufactured coils
100% quality certified by Panasonic is ensured by coil
production in our factory. Hydrophilic aluminium (Bluefin)
treatment is available as standard. Special Epoxy coating
with strong protection against corrosion can be requested
as option.
Hydrophilic aluminium (Bluefin)
Screw compressors.
Screw compressors can be operated
continuously and are therefore suitable for
applications where a constant and
consistent cooling load is required.
Due to their high energy efficiency, our
products use these compressors in
combination with high-efficiency
refrigerants.
