Heat Exchanger

The Komfort EC SB 350 features a polystyrene counter-flow heat exchanger, it has a large surface area allowing for high heat recovery efficiency ranging from 85% to 98%.

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

The unit has an electronic freeze protection system that prevents the heat exchanger from freezing in cold seasons. If the temperature senses temperatures that are very cold, the supply fan turns off allowing the heat exchanger to be warmed by the extracted air. After the freezing danger is over, the supply fan is activated, and the unit runs in standard operation mode.


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

S14 controller features:

  • Use to activate / deactivate the unit

  • 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.

The ductwork connections are located at the top of the unit and feature rubber seals for airtight connections to the ducting system.

The Komfort EC SB 350 is designed to be installed via wall mounting. The units’ casing is universal, if required the side of the air ducts can be changed – you can do this by turning the unit 180° and reverse the front and back panels.

When installing the unit, there must be enough space to connect the condensate drain (condensate drainage kit available separately).
