Radiators with 3 panels and 3 convectors

33

— radiators of three panels and three convectors. Most of these structures resemble a type 22 product (see the relevant paragraph), to which another convector was attached on one side and covered with another panel.

In fact, 33 is the largest type of panel radiator widely used; more elements are extremely rare. The efficiency of such models is high, but the cost, dimensions and weight are also very significant. So it is worth paying attention to them mainly when high heat transfer efficiency is crucial.
