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 plate-fin typed air-cooled condenser applies double-curved corrugated aluminum foil, which is water-contactable. It is manufactured by specialized heat exchanger processing machine. Thanks for being extremely compact and light weight, as well as the high heat exchange efficiency and the ventilator with large rachis in slow revolution, the working noise level is obviously reduced so that the equipment is more environmental-friendly. |
