KORATHERM HORIZONTAL

Design radiators with horizontally aligned profiles and bottom connection

Design radiator KORATHERM HORIZONTAL represents thanks to its heat output a comfortable alternative to a conventional panel radiator. An extensive range of colours and its individual appearance with a characteristic line-design of heating profiles naturally challenges it to be integrated into any modern interior.

It is designed for two-pipe pressurized heating systems, the heating profiles are aligned horizontally. The connection to the heating system is bottom from the bottom down with connecting pitch derived from the length L (example of product code K11H). It is equipped with 2 bottom connections with inside thread G½, an air vent and a blanking plug with G¼ thread. Type 10 is delivered with a solid top cover, types 11, 20, 21 and 22 with a top grill.

KORADO now offers also towel hangers and pegs which extend the practical use of KORATHERM design radiators.
