Low Pressure Centrifugal Oil Separators

Maximum Working Pressure - 450 psig

Description

Centrifugal oil separators are designed to remove large quantities of oil at a wide range of operating capacities. Field tests have shown these oil separators are up to 99% effective - even in high oil loading conditions. For screw compressor applications, a high pressure oil separator/reservoir without internal float valve must be used.

Totally sealed and serviceable units are available. We recommend serviceable oil separators be used in supermarket and parallel compressor systems.

Select an oil separator based on the system's tonnage under normal operating conditions. This is the capacity or compressor(s) BTUs based on refrigerant gas at the saturated suction and condensing temperatures of the operating system. For optimum sizing, select an oil separator with a capacity closest to the system's load at evaporating temperature. Minimum tonnage is 30% of the rated capacity.

All Sealed Units come with a 3/8 Flare for the oil outlet

All capacities shown are based on 100°F condensing temperature.
*Replacement float assembly and gasket available for flanged oil separator (part number W1900-30).
