Heat Exchanger

The Komfort EC SB 550 features a counter-flow heat exchanger constructed of polystyrene, it has a large surface area allowing high heat recovery efficiency.

A drain pan is situated under the heat exchanger, it collects any condensation and is fitted with a drain pipe for condensate removal.

The EC SB unit range includes an electronic freeze protection system that prevents the heat exchanger from freezing in colder temperatures. If the temperature is too cold, the supply fan will turn off, this allows the heat exchanger to be heated by the heat from the extracted air. After there is no longer a freezing danger, the supply fan is activated again, and the unit returns to its standard operation mode.


The Komfort EC SB unit range is supplied with an integrated control system with a S14 wall mounted control panel. A 10m cable is supplied to connect the control panel to the heat recovery unit.

  • Individual speed control for both supply and extract fans

  • Bypass and humidity level control


The Komfort EC SB range is constructed of double-skinned polymer coated steel panels. The panels are internally lined with a 40mm mineral wool layer for heat and sound insulation.
