Universal use – heating and light-cooling!
Developed for low-temperature heating systems, high performance is guaranteed even at very low temperature gradients. Ideal for installations, where the heat source is a heat pump system or condensing boiler. Suitable also as an additional heat source for floor heating, especially in the transitional periods of the year or for rapid increase of room temperature. In summer they can be used to cool the room without causing condensation (drycooling). All these advantages are provided while maintaining the benefits of forced convection, ie. maximum performance with silent fan operation and low power consumption.

Convectors installation – construction recommendations OKIOC

• Wall-mounted convectors should be installed on a peripheral wall, 10 cm above the floor.
• Hot water supply must be connected to the upper pipe, we recommend installing a lockshield and thermostatic valve. (Where the cooling mode is needed – consult the designer.)
• Fans should be installed into the convectors after all building works have been completed. All components must be well protected against dirt. Regular maintenance, including cleaning of fans and exchangers – must be carried out.
• Installation procedure: First the wall brackets are fixed to the wall. The exchanger is placed onto these and connected to the heating system. Before connecting we recommend checking the correct positioning of the exchanger and fittings in relation to the casing.

KORAWALL OKIOC with design front panel
KORAWALL OKIOC wall-mounted convectors display a significant design element on the front panel, repeated on longer convectors. A single pattern appears on convectors 75, 100 and 125 cm in length, two patterns on lengths of 150 and 175 cm, and three on lengths of 200 cm.



Easily removable casing for better access to the heat exchanger (for instance for easier cleaning).

Assembly electrical part

• Regulation is identical for wall-mounted convectors, free-standing convectors and trench heaters with forced convection.
• We recommend equipping KORAWALL OKIOC with thermoelectric actuators.
• A power supply must be available near the convector. For more details see the Installation instructions provided.

12-V convector regulation - termination of sale
Starting from March 2020 we terminate production and sale of 12-V convector regulation. This type of regulation can by fully replaced by 24-V version. This regulation is safe and fulfills  all requirements and functions  our convectors demand.
Thank you for your understanding.
