EcosmartAir cooled class-A chiller


Model CA
INVERTER driven SCREW compressor
Cooling capacity: 167 to 410 kW

The Ecosmart Inverter driven chillers provide low temperature water assuring the highest energy efficient functioning.

INVERTER TECHNOLOGY works on the principle of variable compressor motor speed; an electrical signal is given to the compressor motor to adjust the screw speed according to the thermal load. If the thermal load is high the compressor runs faster developing a higher refrigerant flow rate and accordingly increasing the cooling power; on the contrary, the inverter reduces the refrigerant flow rate reducing the cooling power supplied consequently.


High efficiency: highest EER in any working condition (partial loads)
Inverter driven screw compressor: stepless continuous modulation from 25% to 100%.
Inverter driven fans: air flow continuous adjustment
Internal pump inverter driven: to have stable values of pressure of water process in any working condition.
Oversized condensers evaporators: in order to have the best efficiency of
EEV electronic expansion valve to reach the high est water temperature stability (+/- 0.4°C in the evaporator outlet)
Extended compressor life: no inrush current
● Lower friction
Safe functioning: differential pressure switches, oil flow switches, water flow switches
Simplified installation(indoor or outdoor), with facilitated and quick startup operations.
Eco-compatible:green refrigerant R134a.
Low noise operation level
