Universal use – heating and dry-cooling!
Developed for low temperature heating systems, high efficiency guaranteed also at very low temperature gradients, e.g. 35/30 °C. Ideal everywhere, where the heat source is a heat pump, a solar system, a condensation boiler or as a supplementary source of heat for floor heating, particularly during a transitional period or when an instant temperature increase in the room is required. At the same time suitable for rooms' dry-cooling during the summer months. All of this with the benefits of the Optimized Convection system – low noise and low fan intake while maintaining maximally attainable performances.

• high efficiency even at low temperatures of the heating system
• patented design solutions
• high-perfomance, low energy and quiet fans
• the same regulation as the one for floor convectors and free standing convector with fan   assisted 
• two pipe system
• right bottom connection
• possibility of control through BMS (Building Management System)
• the convector is intended for dry environment

Convectors installation – construction recommendations OKIOC

  • It is recommended to position the wall mounted heating element on a peripheral wall, 10 cm above the floor.
  • The hot water supply always in the upper pipes; recommend to fit with the stop valve and the thermostatic  valve (consultation with the designer is required in case of cooling).
  • We recommend to fit the fans once all building work is completed. The exchanger and the sheathing must be  well protected against fouling and regular maintenance carried out – including cleaning of exchangers and fans.
  • The convector is fitted to the wall using brackets. Then the heat exchanger is inserted and connected to the heating system. We recommend to check the correct position of the exchanger and the fittings in relation to the  sheathing. Fit the fans and the sheating only after all building work has been completed.

Design solution of the front face of OKIOC

The wall mounted heating elements OKIOC have on their front face a significant design element, which consists of one design section in the lengths of 75, 100 and 125 cm, two sections in the lengths of 150 and 175 cm and three sections in the length of 200 cm.



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

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.
