SKW Compact

SKW Compact unit is made to be installed as a ready package. Although the unit can be split for installation at site.

Unit is designed for high heat recovery efficiency, up to 90%, with the lowest available pressure drop at the same time. Compact units are available up to 5000m3/h (Larger ones on request).  Counterflow unit can be selected in different categories adapting to the condition needed.

Normal counterflow unit is made from aluminum, special counterflow units can be equipped with nano foil material for latent energy recovery.

For swimming pool use the system will be equipped with epoxy coated heat recovery system.SKW Compact Pool use epoxy coated aluminium heat-exchangers.

Facilities: Private pool, Private house, Office small

Basics of Skawen ventilation technology

Dehumidifying devices for private
and public swimming pools

The ventilation and dehumidifying devices provided by Skawen are the result of decades of experience in the development and production of ventilation units.

The most important features are maximum economic efficiency in operation and sustainability in terms of long life-cycle and resource conservation.

Compact systems with various functional features are used for comfort in swimming pools. These features enable simple and precise implementation when installing the systems in new buildings or at renovations.

Due to the possibility to configure the air connections the devices are also space efficient.

The devices are usually set up in the technical room and connected to the swimming pool through air ducts (supply and exhaust air).

The air ducts for outside and exhaust air are led outside. It should be noted here that the exhaust air is led away from the house in order to avoid condensation on the building structure.

In the swimming pool, the supply air is brought in via air outlets in front of the windows.

The exhaust air should be extracted at several points in the room in accordance with VDI 2089.

Several levels of heat recovery can be used in swimming pools. During the planning phase of a project, the right device concept can be chosen by asking about how it will be used. More complex technology is not always more economical!

With classic dehumidifiers, if the pool is covered for more than 22 hours a day, for example, a heat pump does not make sense, as evaporation is reduced to a fraction.

With devices from Skawen, the heat is reclaimed with the help of a recuperator and, if you want, a heat pump further down the line. The heat pump is output-regulated and is used exclusively for heat recovery.

The housing of the ventilation unit consists of anodized,
self-supporting thermally separated aluminum profiles.

The double-walled panels (50mm) are filled with non-combustible mineral thermal insulation, at least class A (DIN4102). The 3 mm thick sheet is filled with a 2.8 mm thick sound-absorbing compound and is therefore already very quiet as standard.

The inner and outer sheets are thermally separated from each other.

For maintenance purposes, the devices are equipped with removable panels with handles or wing doors, depending on the unit size and type.

The energy recovery system of the plate heat exchanger is completely built into the air handling unit and has a condensate collecting tray as well as an integrated bypass flap system for temperature and demand-dependent frost protection control.

The filter system, which is so important for hygiene, is designed in accordance with the CEN EN 779 standard in order to be able to keep a constant maximum air quality in the room. This is continuously monitored by the control system integrated in the unit.

State-of-the-art eC fans of the latest generation regulate the required air output for supply and exhaust air as required.

The control and regulation of the device takes place via a DDC system with self-optimizing mode of operation for the removal of moisture from the swimming pool.

Optionally, the systems can be equipped with a highly efficient controllable heat pump for energy recovery and a pool water condenser.

When operating with a heat pump, energy is recovered from the exhaust air in a regulated manner that is adapted to the operation. Economical operation of the heat pump can only be guaranteed through this operating mode.
