Henry Group Industries Helical Oil Separator

The Henry Group Industries Helical Oil Separator removes oil from the compressor discharge gas in commercial air conditioning and refrigeration systems. It returns the oil to the compressor, either directly or through an oil management system. This helps keep the compressor crankcase oil level steady. It also improves system efficiency by preventing excess oil from circulating through the system. The line is also known as a refrigeration oil separator or compressor discharge oil separator.

Key Features:

• Helical, centrifugal design: Oil-laden gas is forced along a spiral path. Heavier oil particles spin to the perimeter and collect on an internal screen. The screen strips the oil and drains it away.
• High separation efficiency: Henry rates the helical design at up to about 99% oil separation, with low pressure drop.
• No moving parts in the separation zone: There are no coalescing elements to block, and no oil blow-out at start-up from oil left in an element.
• Baffled oil collection chamber: The baffle isolates the oil chamber and prevents turbulence, so separated oil is not re-entrained.
• Float-controlled oil return: A float assembly in the collection chamber meters oil back to the compressor or oil management system. The 3/8" flare oil return connection and ODS refrigerant gas connections are shared across the line.
• Rugged construction: Carbon steel shell, end caps and connections. The oil float is stainless steel.
• Operating range: The S Series is rated for a maximum working pressure of 31 barg (449.6 PSIg). Its operating temperature range is -10°C to +130°C (+14°F to +266°F).
• Refrigerant compatibility: Suitable for HCFC and HFC refrigerants and their associated oils. Henry's literature lists broader compatibility for some models where materially compatible.

Application Notes: Helical oil separators are commonly used on multi-compressor racks and remote condensing units. They are intended for low-pressure oil management systems and for scroll and reciprocating compressors. They are not recommended for screw or rotary vane compressors. Henry Group Industries was established in 1914 and makes components for commercial refrigeration and air conditioning.
