KORAWALL OKN wall-mounted convectors are standard wall-mounted convectors with a long history, used in households as well as in commercial premises. Modern design, easy installation and economical operation are some of the reasons why they are so popular with our customers. The unique design of our heat exchangers achieves higher outputs even with small dimensions of the element. Low surface temperature of 40 °C and no heat dissipation into the wall are great advantages of KORAWALL OKN wall-mounted convectors.

PLAN model – a design solution with a perfectly flat front panel.
