| Water Cooled Screw Chiller |
NITSU Screw chiller incorporate advanced semihermetic screw compressors, with extra large cooling capacity and reliability. Temperature rang from 3°C to 30°C.
Consisting of air-cooled and water-cooled models, capacity range from 68,800 to 2,941,200kcal/h (compressor rating from 22 ~ 720kw).
Capacity control in 4 stages (100% - 75% - 50% - 25%). Screw chillers are generally suitable for large cooling applications. |

The water-cooled chiller consists of a recumbent shell-tube condenser and a fin-tube shell evaporator. With the advantages of concise structure, stable heat exchange, endurable efficiency and easy maintenance, the water-cooled chiller is well known as an ideal unit for central air conditioning system. |
