The PURMO Plan Ventil Compact M panel radiators with mid-bottom connectors stand out due to their completely flat front panel. The panel is glued to the profiled, front base heating panel in a manner concealing any protruding edges, when looking at the radiator from the front. The radiators are equipped with convection fins as well as side covers and a top grille. Two mid-bottom and four side G ½" threaded female connectors allow for central bottom or side connection. The radiator is also equipped with a built-in thermostatic Oventrop valve insert providing pre-setting. The main advantage of the central bottom connection relies of the fact that regardless of the length, height and depth of the radiator, the layout of heating system connections can be defined at the building shell stage and it will not change as a result of the selection of a specific size and type of the radiator.
