PETChillerSelf adjustable and auto-adaptive to cut energy utilization to half in PET production

PETChiller

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).

Benefits

● Highest COP values now available on the market.
● Auto-adaptive functioning
● Stable process conditions
● Accurate Temperature control
