Oil Separator

The task of the helical oil separators is to separate oil from the discharge refrigerant correctly and ensure oil return to the com- pressor most effectively. The purpose is to maintain crankcase oil leveland increases the efficiency of the system by minimizing the excessive oil circulation. Helical oil separators are designed for low pressure oil managment systems, they can be used invarious sys- tems and multiple compressors. The products are designed for use with scroll and piston com- pressors, they are not recommended for screw or rotary vane compressors. Standard product series are designed for use with HCFC & HFC refrigerant with the relevant oil (please contact us for ammonia system refrigerants). Helical system and stainless filter system in the product are more effective in separating oil than standard oil separators. The sur- face of the oil separator is wrapped with a stainless filter, so that heavier oil particles adhere through helical path, separate from discharge refrigerant and drains. Gas/oil mixture is moved along spiral path by centrifugal force, and oil particles revolve on sur- face of perimeter and collide with layer. Oil drains from the flter screen to the reservoir at the bottom. Refrigerant passes through the filter and leaves the oil separator from outlet connection. When oil level rises in the reservoirs, float ball rises and oil returns to the crankcase by passing through oil return connection.

Application Field

It is strongly recommended to use oil separators under the following conditions:Low evaporation temperature applications, capacity controlled systems, parallel connected compressors, flooded evaporators, blast freezer, two-stage compressors, cascade systems, long line systems.

Selection

Oil separator selection is made according to the refrigeration technical rules and oil separator connections must not have smaller diameter than discharge line size.

Technical Specification

• Helical oil separator types are products with float system.

Float system;

• Stainless steel and brass raw materials are used,

• It is protected against to pressure and circulation will occur in- side the product,

• Any contamination which may occur in the system can be easily caught by magnet in float system at oil outlet, thus it ensures that valve operates in a cleaner environment.

On standard products;

• ODS connection is used for inlet & outlet,

• Oil return connection 3/8”SAE is used,

• (OS.HF) Active parts may be replaced when needed,It is produced in accordance with CE 2014/68/EU [PED] pressure equipment directive.

Warning

• Please ensure that the float system is not damaged and it is working properly.

• Before installing flange connection, ensure that O-ring channel is clean and not damaged. Place the O-ring into the channel correctly and mount by tightening bolts with equal torque.
