MAGNUM Front Steel

 Floor heating manifold 

 This MAGNUM control unit is very compact and made of galvanised and epoxy coated steel. This allows MAGNUM to give a 5-year guarantee on the housing of this manifold. The manifold is equipped with a Grundfos ALPHA2 L pump as standard. Standard with a primary top connection. This pump has a constant pressure, so it adapts itself when groups are closed off by a possible after-control (actuator). 

The manifold is hydraulically neutral, which means that the pump of this manifold has no influence on the primary circuit. Description Dimensions
