Neo is an under-window radiator featuring high efficiency and minimal depth. The heater, including mounting hooks and a plumbing outlet, extends only five centimeters (two inches) from the wall. The radiator is built of vertical modules joined at the top and bottom with horizontal collectors. The modules are injection-molded aluminum and the collectors are welded steel profiles. Neo owns its efficiency and compact size to the form of modules which are shaped as boards with radiation ribs at the back. The modularity of the heater permits production of radiators in different lengths and various color combinations.
