The innovative CRW-TRY/DR 1330/1÷41750/1 units for Dry-Cooler operation, with R134a refrigerant, featuring A CLASS energy efficiency, are designed to provide an effective solution for highly selective system needs. Efficiency at partial loads, low breakaway starting current, low levels of operational noise, reduced weight and the specific design and handling every manufacturing aspect, make the CRW-TRY/DR 1330/1÷41750/1 series the top of the range.
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-TRY/DR 1330/1÷41750/1 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.
