What is a progressive mixer characteristics curve ?

A mixer with a special 3D rotary vane design always produces the same pressure drop over the entire control range at different volume flows. This achieves a high control quality. This can be recognized by a quiet servomotor that can control a constant flow temperature even at low volume flows....

What does GEG compliant thermal insulation mean ?

Pipes and fittings must be insulated at 50% of their nominal diameter at junctions, crossings and central manifolds in accordance with the Building Energy Act (GEG). For heating circuit groups, this means a fully enclosing minimum wall thickness and separation of the flow and return lines. The Tuxhorn tubra®-PGM/PGR pump...
