The innovative TWH 291÷4061 TT/Y TURBOLINE units for cooling tower operation, featuring A CLASS energy efficiency, are designed to provide an effective solution to 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 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 values, with minimum water content, and an excellent silent functioning. Compared to traditional Screw compressor units, units have low operational costs during their entire use, with a savings that can even reach 50%.
The units are compliant to the 2021 ErP Regulation.

On request, units can be supplied with R513A refrigerant.
