OSO Fix - MX/PV

  -  

The Fix assembly centrals are the perfect accessory for OSO indirect units. They contain all necessary equipment for the space heating system, factory assembled in an OSO ECO Foam insulated box. The Fix provides neat installation and reduces fitting time for the installer. Suitable for space heating systems up to 20kW.

The installer needs only connect the flow and return from the heating system, and the units will effectively hide most pipes and connections. Suitable for all OSO indirect units, such as the Ecoline and the Optima. The MX units are supplied in two versions, one for high temperature distribution systems such as radiators, and one for low temperature, such as under-floor heating. The PV is suitable for systems utilizing a heat pump, and does not include a shunt valve.
