Air - heat pumps TERRA AL 17-32 Twin

High performance for larger buildings and requirements

In colder regions or in harsh winters, the demand for higher heating capacities is increasing. Or larger buildings require equipment that can reliably meet the higher performance requirements.

The TERRA AL Twin series with output values of 17/24/32 kW perfectly adapts to these different requirements with partial and full load operation. The heat pump operates with one refrigeration circuit and two compressors and enables power-dependent step switching. During the transition period, the heat pump can work in highly efficient, single-stage operation and thus achieves the best annual performance factors.

Due to the high air throughput at heating outputs of 24 kW and more, outdoor installation is much easier than indoor installation - there are no air ducts.

A comprehensive range of product accessories for control, connection to the heating side, for cooling, etc. can be found in the overall PREMIUM heat pump price list, which you can find in the downloadarea.
