KORATHERM HORIZONTAL – High output low Flat Panel End Ports



KORATHERM flat panel radiators are designed for double-pipe heating systems with forced circulation of the heat-carrying agent. The new types 23, 44 and 46 extend the product range of KORATHERM HORIZONTAL models and thus allow for their use in more areas. All of these radiators are supplied with an upper covering grille and can only be fixed to the floor with the aid of special stand brackets.

Closed steel profiles are used for the heating elements with a rectangular cross-section of 70 x 11 mm, dividing and collector profiles have a cross section in the shape of the letter “D” with dimensions of 40 x 30 mm. Heating profiles are aligned horizontally. The types are supplemented with an additional convector fin with a depth of 45 mm.

Connection of the KORATHERM HORIZONTAL model to the heating system is bottom from the bottom down and its connecting pitch is dependent on the length of the radiator L. Types K23H, K44H and K46H are manufactured up to a maximum length of 3000 mm.
