The innovative TWH/DR 291÷1541 TT/Y units for Dry-Cooler operation, 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, specific design and handling of every manufacturing aspect, make the 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 SEER/IPLV values, with minimum water content, and an excellent silent functioning. Compared to traditional Screw compressor units, TURBOLINE units have low operational costs during their entire use, with savings that can even reach 50%. Besides, the units are equipped with 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.
The units are already compliant to ErP 2021 European Regulations.

On request, units can be supplied with R513A refrigerant.
