-50℃ To -30℃ Air Cooled Condensing Units 2 Stage Refrigeration Unit
Two Stage Air Cooled Screw Condensing Unit – No 1 Refrigeration Unit (-50~-30℃)
With the growing refrigeration market, we are offering a Two-Stage Air Cooled Screw Condensing Unit with premium parts.
Product Description
With the growing refrigeration market, we are offering a Two-Stage Air Cooled Screw Condensing Unit with premium parts. Perfect as a refrigeration storage and quick freezing device, this condensing unit is an economical option across the world. Our air-cooled condensing unit is free from Freon piston compressors that never meets current standards. To overcome this issue, we have launched the SLLG series low-temperature semi-hermetic condensing unit to fulfill the requirements of large scale refrigeration.
Moreover, we always manufacture and test all Two-Stage Air Cooled Screw Condensing Unit parts carefully to maintain OEM-QUALITY standards.
Features:
· Our upgraded Two-Stage Air Cooled Screw Condensing Unit has original semi-hermetic Taiwan Fusheng two-stage screw compressor.
· The compressor has less noise, less vibration, long life and matchless efficiency.
· Completely configured unit with world's highly reliable refrigeration accessories and parts.
· Over load, over heat, counter rotation, exhaust temperature, oil flow, oil level, and pressures level protection.
· Integrated economizer for enhancing cooling capacity even at low temperature.
· Adjustable multiple energy regulation levels for different cooling load.
· Less energy consumption.
