The innovative CRW-TRH 1340/1÷62120/1 units for cooling tower operation, featuring A CLASS energy efficiency and HFO-R1234ze refrigerant, are designed to provide an effective solution to highly selective system needs. The latest generation refrigerant HFO-R1234ze, with GWP<1 (Global warming Potential), is the most environmentally sustainable refrigerant on the market, and meets the strictest international environmental regulations. Furthermore, thanks to Turbocor compressors, the units perform with top efficiency at partial loads, low inrush currents, an excellent silent functioning and reduced weight.
Using TURBOCOR dynamic partial-load oil-free magnetic levitation compressors, managed by the TURBOSOFT self-adaptive electronic control and flooded shell and tube evaporators, provide high energy performance, with unbeatable SEPR/ESEER/IPLV values, with minimum water content, and an excellent silent functioning. Compared to traditional Screw compressor units, CRW-TRH 1340/1÷62120/1 units have low operational costs during their entire use, with a savings that can even reach 50%. Besides, the units are equipped with the WEB MONITORING system, for remotely managing and monitoring the units by means of GPRS/EDGE/3G/TCP-IP communication protocol. The users enabled to use this service can, by a dedicated Web page, access Monitoring, Management and Statistics activities.

Versions

  • CRW-TRH - Cooling only for cooling tower

Features

  • Structure with supporting frame, made of galvanised sheet metal with additional protection provided by polyester powder coating.
