Key Features

Six core advantages that keep your refrigeration system protected around the clock

💧

Multi-Stage Separation

Impact, filtration and centrifugal stages reach over 99% oil separation, cutting oil entering the system and lifting heat-transfer efficiency.

🔍

Float Needle Valve

A built-in float needle valve returns separated oil to the crankcase automatically - no manual action, constant lubrication.

🛡️

TP2 Copper ODF Ports

Inlet/outlet use TP2 copper with ODF connections for easy brazing and fewer installation hours.

🌡️

Welded Carbon-Steel Shell

A welded carbon-steel shell passes a strict 1.5x design-pressure test for a reliable seal.

Protects Heat Exchangers

Prevents oil films coating condenser/evaporator walls that otherwise lower efficiency.

🔧

Broad Model Range

KW-80 to KW-1500 cover small to large systems and displacement demands.
