WK-compact PT H
plug-in energy-efficient ventilation unit for indoor and outdoor installation
Heat recovery
Designed as a counterflow plate heat exchanger for utilising the sensitive and latent heat energy contained in the air streams. Exhaust and outdoor air flow
are completely separated from each other.
They pass along each other by thin aluminum panels arranged in parallel by countercurrent.

EC technology
EC motors have a significantly lower power consumption than conventional three-phase AC motors. With the EC motor technology, efficiencies of approximately 96% can be achieved over a very wide revolution speed range.
The continuous controllability guarantees optimal adjustment of the system efficiency, which is very easy with a 0-10 V signal.
The EC ventilator motor is not only very effective, but also long-lasting, maintenance-free and quiet.

Z-line filter / pocket filter
In addition to high strength and stability under heavy load, the air filter
is characterised by one thing in particular:
Its low energy consumption, for an environmental consciousness that pays off.By default, with Z-line filter, available with optional pocket filters.

Housing
Housing consisting of 42 mm thick double-walled panels with very good
sound insulation.
The inner and outer shell is made from 1.0 mm galvanised sheet steel coated in RAL 7016 / anthracite grey. Alternatively, the panels can also be made of aluminum or stainless steel.
Profile frame made from aluminum, optional stainless steel.
Design and construction according to DIN EN 1886 and based on VDI 6022.
Also available in weatherproof design, i.e. with roof and suction hood (ODA/AUL).

Recirculating air flap
Optional: The recirculating air flap can be opened for fast and energy-efficient heating of a room. The counterflow plate heat exchanger and the bypass are closed simultaneously and automatically via servomotors and flaps, so that the
heating can be performed with 100% of the circulating air.
Bypass
In order to avoid unnecessary heating of the outdoor air in the summer, the bypass flap can be opened and the flap on the countercurrent plate heat exchanger can be closed.
With this flap setting a night cooling can be performed using the control system. The cool outdoor air is thus blown directly into the room past the plate heat exchanger at night.

Control
WOLFtronic© ensures simple and convenient operation
By means of this regulation and control system specially developed for the WK-compact device, all important settings can be made conveniently. Select the operating mode, temperatureor desired operating time.
System-specific ex works
For a customer-friendly initial operation, the WOLFtronic© system is already configured for any specific customer installation ex works. For the initial operation of the heat recovery unit, only the target values, revolution speeds and circuit times must be adjusted individually by the customer.
