The new WPF heat pump series has been developed especially for the purpose of heating larger apartment buildings as well as commercial and industrial buildings. With its dynamic curved lines, it documents a high degree of independence, dissolving the conventional rectangular format. The soft, positive form of the stained and anodised aluminium faceplate creates an aesthetic and unified interface between man and machine. Operation and selection of materials for these heat pumps meet the demands for technically sophisticated products geared to reliability and functionality, and the modular construction allows for both side-by-side and stacked installations. Up to six individual modules can be combined to a finely stepped cascade, allowing a well-aligned performance adjustment for nearly every type of building.
