Specifications

Screw-type oil separators are especially designed for screw compressors.

GENERAL DEFINITION

• Screw-type oil separators are especially designed for screw compressors.
• These oil separators are suitable for all HFC-coolers and cooling circuits with R22 application.
• Products with 4 different volume are manufactured as standard:(BLR/OSD-180x2, BLR/OSD-400x2,BLR/OSD-900x3, BLR/OSD-1300x3 )

Connection Parts

• We determined Input and Output connections according to volume of products.
• Rotalock valve connection is used in standard products.(Flare/Flare)
• Different connection may be used upon request.
• 7/8” Rotalock Valve is installed at tank output in standard poducts. 
• We determine models of Sight Glass according to diameter of products. 
• Sight glasses may be decreased and increased up to desired number. 
• 2 Sight Glasses are available in standard products. 
• We strongly recommend using Safety Valve in products. 
• There is a Safety Valve connection after certain volume. 
• We strongly recommend using Liquid Level Sensor with products.
