KORAWALL Optimal-V WVO

standard fan-assisted design

KORAWALL Optimal-V WVO wall-mounted convector is an efficient, energy-saving forced-convection heating unit and has a light cooling function. It is equipped with a set of high-performance, low-energy fans. Our wall-mounted units achieve high heating efficiency, even at low-temperature gradients. Convectors with forced convection are ideal for installation situations with heat pumps, solar-energy systems, condensing boilers, or as an additional heat source for underfloor heating. They have the advantage of being a source of pleasant heat during the seasonal transition periods of the year. If needed, they can provide a rapid ambient temperature increase. Their light-cooling ability offers an additional option in summer. Wall-mounted convectors with fans can be operated via BMS. They react to changes in ambient temperature immediately, have very quiet operation and low surface temperature. These features of wall-mounted convectors with fan make them ideal for installation situations involving not only family houses or apartments, but also for use in public buildings.

Construction part
  • We recommend placing the wall-mounted unit on the perimeter wall, 100 mm above the floor.
  • We recommend equipping the convector with the LM regulation valve with a higher flow rate.
  • The water inlet must always be connected to the pipe leading to the upper part of the convector and also attach the LM regulation fitting.
  • The heat exchanger and casing must be well protected against contamination. Heating units must be regularly serviced; heat exchangers and fans cleaned.
  • The unit is installed on a wall using the rear weight-bearing part. We recommend checking the correct positioning of the heat exchanger with fittings and the casing prior to connecting the heat exchanger to the heating system.
  • The regulation is identical for KORAFLEX FV trench heaters and KORALINE LV freestanding convectors.
  • We recommend equipping the KORAWALL WVO and WVP with a thermo-electric actuator.
  • Do not forget to install the power supply cable near the unit installation site.HPS
info  The unit is designed for cooling in the non-condensation zone only, i.e. above the dew-point temperature. The unit is not equipped with condensate drainage.
