COMPRESSOR PROTECTIVE DEVICES
The function of a Helical Oil Separator-Reservoir is to remove and
store oil from the discharge gas so that it can be returned to the
Helical Oil Separator-Reservoirs can be used in a variety of applications.
Common applications include multi-compressor racks. Helical Oil Separator-
Reservoirs are intended for High Pressure Oil Management Systems.
These products are designed for use with scroll and reciprocating type
compressors. They are not recommended for screw or rotary vane
compressors. Henry Technologies’ Oil Separators are suitable for use with
HCFC and HFC refrigerants, and their associated oils, as well as other
industrial fluids non-corrosive to steel, copper and Teflon.
How it works
The Helical Separator does not rely on any moving parts for oil separation.
As the oil laden hot gas enters the separator it is directed in a spiral motion
around a helical flighting. The centrifugal forces act on the gas/oil mixture
causing heavier oil particles to spin to the perimeter where they impact an
internal screen. The screen layer functions as both an oil stripping and
draining medium. Separated oil flows downward along the boundary of the
shell through a baffle and into an oil collection chamber. The specially
engineered baffle isolates the oil collection chamber and eliminates oil re-
entrapment by preventing turbulence. The virtually oil free refrigerant gas
then exits through a screen fitting just below the lower edge of the helical
flighting. Oil Separator-Reservoirs do not have an oil float assembly. Instead,
a dip tube is located in the oil chamber that feeds oil to the compressor
through a High Pressure Oil Management System.

Installation - Notes
Full instructions are given in the Product Instruction Sheet, included with
each Oil Separator-Reservoir.
Henry Technologies' Oil Separator-Reservoirs rely on adequate gas
velocities to allow for oil extraction from the hot gas so sizing according to the
DCFM rating is important. The Oil Separator-Reservoir DCFM Rating table
shows the min/max ratings allowed for sufficient separation and low pressure
drop. When sized correctly the Oil Separator-Reservoir models will separate
up to 99% of the oil from the hot gas. Please contact Technical Support at 1-
