Product Description

With the development in the refrigeration field, many large size instant frozen devices, ice-making units, and large-scale refrigeration storages are coming to the market. Among these, some units are unable to work on a large scale. So, we are introducing this upgraded two-stage water-cooled screw condensing unit. With -50～-30℃ temperature settings, this condensing unit meets your wide-scale refrigeration needs.

We always manufacture and test parts of all Two-Stage Water Cooled Screw Condensing Units carefully to maintain OEM-QUALITY standards.

Features:

· Our upgraded two stage water 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.

Main Components:

· Condenser (for water-based cooling units only)

· Oil circulating components

· Reservoir

· Liquid filter pipe

· Sight glass

· Economizer

· Inhales filter

· Pressure protector

· Pressure gauge

· Control box with PCL+ and touch pad

Customized options:

We are currently offering the following customizations;

· Single compressor units

· Two parallel compressor units

· Three parallel compressor units

Please contact us if you need a two-stage water-cooled screw condensing unit for other refrigerants. Moreover, this Two-Stage Water Cooled Screw Condensing Units with all measurements and parts is compatible with R22 refrigerant.
