S-52-series Henry Helical Welded Oil Separator

Henry Helical Oil Separators

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 flow out of the separator is controlled by an oil float assembly in the bottom of the collection chamber. The oil may be returned directly to the compressor or to an Oil Management System.

Applications

Helical oil separators can be used in a wide variety of applications. These can include multi-compressor racks and remote condensing units. Helical oil separators are intended for Low-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. The product range is designed for use with HCFC and HFC refrigerants, along with their associated oils.
