Heat Exchanger

This unit has two types of plate cross-flow heat exchangers

-       Aluminium heat exchanger – recovers extract air sensible energy

-       Polymerized cellulose enthalpy heat exchanger – recovers sensible energy and latent energy from the extracted air.

These heat exchangers are ideal for use in colder climates as they feature frost protection and they produce no condensation. There is an integrated electronic frost protection which prevents freezing in cold seasons. In case of the heat exchangers freezing the temperature sensor the supply fan is stopped to let warm air into the heat exchanger, once the supply fan is turned on the unit reverts to normal operation.

The air flows within the heat exchanger are fully separated, no odour or contaminants that are contained in the air will be transferred to the supply air.


The unit has three selectable speeds that are controlled by an external DCP-3/5 speed switch:

1 – 57 m3/h, 24 dBA

2 – 78 m3/h, 32 dBA

3 – 106 m3/h, 41 dBA


The outer casing is constructed of double-skinned aluzinc panels and features mounting angles for easy installation. The panels are internally filled with a 15mm PE foam layer for sound and heat insulation.

The spigot connections are situated at the sides, they are rubber sealed for airtight duct connections. Both the supply and extract spigots have backdraft dampers.

To allow ease access for cleaning and maintenance the unit features a hinged side panel.


Komfort Ultra D105-A has asynchronous motors for both supply and exhaust. The unit features a centrifugal impeller with forward curved blades, this ensures a high air pressure with a low noise level. The fans are equipped with ball bearing for longer service life.
