Semi-hermetic Screw Chiller

Introduction of R717 Compressor:

R717 compressor is an efficient and reliable industrial refrigeration equipment. R717 compressor adopts 3 phase screw compressor technology. And R717 compressor controls the cooling water temperature through refrigerant circulation. Ammonia gas compressor adopts pumpless design. And ammonia gas compressor uses system pressure difference to lubricate various moving parts, safe and reliable. The 3 phase screw compressor is highly efficient and energy-saving. The 3 phase screw compressor runs stably. Ammonia gas compressor is easy to maintain.  And R717 compressor is widely used in industrial refrigeration. The 3 phase screw compressor is used in commercial air conditioning. co2 screw compressor is safe.

Features of R717 Compressor:

1. Co2 Screw Compressor High Efficiency:

Our R717 compressor comply with GB19577 "Energy efficiency limit values and grades for chillers" standard. R717 compressor use efficient and reliable semi-hermetic compressors.And double screw compressor uses perfect protection systems. And co2 screw compressor also use highly intelligent control systems. The condenser and evaporator of the ammonia gas compressor use high-efficiency heat exchange tubes. Double screw compressor is reliable.

2. Co2 Screw Compressor Reliability:

The R717 compressor adopts a pumpless design. And R717 compressor uses the system pressure difference to lubricate the moving parts. Ammonia gas compressor further improving the reliability of the unit. The semi-compact heat exchanger of double screw compressor is lightweight, efficient and reliable.

3. Co2 Screw Compressor Practicality:

The R717 compressor has a capacity adjustment function. Double screw compressor can automatically adjust the compressor operating status according to the preset temperature of the second refrigerant. Our double screw compressor is widely applicable: condensing temperature of co2 screw compressor ≤45℃, chilled water outlet temperature of co2 screw compressor: +3~+12℃, chilled water inlet and outlet temperature difference of ammonia gas compressor: ≤10℃. If the second refrigerant is ethylene glycol, the chilled water outlet temperature of ammonia gas compressor can be as low as -5℃.

Specification of LSBLG Series Semi-hermetic Screw Chiller:

Series of Ammonia Gas Compressor:

Our product 3 phase screw compressor unit series, piston compressor unit series, lithium bromide absorption chiller series, condenser and cooling tower series, etc.

Use of Double Screw Compressor:

The 3 phase screw compressor are mainly suitable for office buildings, hotels, shopping malls, hospitals, food processing plants, breweries, chemical plants. In addition, 3 phase screw compressor are also widely used in central air-conditioning systems of mechanical processing plants, industrial plant air-conditioning systems, low-temperature air-conditioning systems of food processing plants, production processes, etc.
