China Industrial Low Temperature Water Cooled Type Screw Water Chiller

BRIEF DEscriptION
Industrial Screw Type Water Chiller Unit has a wide cooling capacity range from 90KW to 3460KW. This series unit adopt 5:6 Asymmetric Semi-closed Twin Screw Compressor, High-efficiency Shell & Tube Dry Type Evaporator, High Efficiency Internal Thread Copper Tube Fin Type Condenser etc. Industrial grade design with built-in multiple security protections, high efficiency, low failure rate, low noise, anti-vibration, high precision temperature control.
Air-cooled type unit can work independently without cooling tower, suitable for water shortage areas, but water-cooled type has a better cooling performance with low energy consumption. The cooling medium for this series could be water, glycol solution or salt solution, supply chilled water through refrigerating cycle for air-conditioning or other industrial equipment. Our chiller unit obtain pretty appearance, reasonable layout and convenient for using &maintenance etc.
