PETChiller - High efficiency line

This range of chillers adopts state-of-the-art cooling devices to reach the highest performance in terms of efficiency, accuracy and reliability.

The PETChiller 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.

Main features

Inverter controlled screw compressor: (stable process conditions and optimised energy utilisation).
Inverter controlled process water pump: (the quantity of water to supply to the utilities is automatically determined based on the temperature differential in/out).
Braised plate stainless steel heat exchangers.
Electronic expansion valve (modulation, control and regular gas expansion are key for a process that on top of being efficient must also be very accurate).
Accurate temperature control (accuracy of 0.1ºC, versus temperature variations of 1ºC and more of conventional chilled water systems).
