KORAWALL Direct WVD (24 V DC)

connection via adapter to 24 V DC

Wall-mounted convector with forced convection, autonomous control and 24 V DC connection.
The KORAWALL Direct WVD wall-mounted 24 V DC convector is a powerful fan heater suitable for low-temperature heating. The convector is equipped with a specially designed Al/Cu heat exchanger in RAL 9005 lacquer and a set of low-energy quiet fans. The convector is equipped with an autonomous control with an integrated keypad, allowing fans to be controlled directly on the unit. Connection to the mains is via a 24 V DC socket adapter. The convector achieves high heat outputs even at low-temperature gradients, and in non-condensing zones it can also be used for aftercooling, which is particularly advantageous in the summer months. The convector is well suited for a range of building types from new builds, private houses, office buildings to refurbishments and wherever the heat source is a heat pump, solar system or condensing boiler.

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.
  • KORAWALL Direct VWD is to be used with a thermostatic head for heating and cooling
  • Do not forget to install the power supply cable near the unit installation site.
  • The convector is equipped with an autonomous control with an integrated keypad, allowing fans to be controlled directly on the unit.
  • Connection to the mains is via a 24 V DC socket adapter.
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.
