TKVR can also be used together with receiver pressure regulator type TKVD.

The TKVP is mounted in the suction line after the evaporator

TKVC is a capacity regulator used for the adaption of the compressor capac-ity to the actual evaporator load.

TKVLcrankcase pressure regulator protects the com-pressor motor against overload during start-up after long standstill period or after defrost periods (high pressure in evaporator).

The Recirculating lnjector is a simple device that uses the energy of high-pressure refrigerant to get maxi-mum heat transfer in an evaporator. The usual application is the fixed charge type, that is, a single com-pressor with a single evaporator, Recirculating iniectors have their areatest use with ice builders, milk cool-ers, Baudelot-type chillers, farm tanks,slush freezers, and many types of freezing plates.

Thermostatic expansion valve regulate the flow rate of refrigerant liquid Into the evaporator.

Fitted in by-pass line between compressor discharge and suction line in refrigeration or air conditioning units.

Constant pressure valve is mainly used in cabinet air conditioning, ice machine, drink machines, cold water machine, dehumidifier, experimental apparatus and other small refrigeration systems.
