REK+ aluminium heat exchangers form an essential part of our product range. They are distinguished by their unique plate geometry, which has been developed in cooperation with specialists from the Technical University of Liberec, Czech Republic. As a result, these heat exchangers achieve maximum possible efficiency and low pressure drops.

REC+ aluminium heat exchangers are the perfect way of switching from a crossflow to a counterflow heat exchanger. They meet Ecodesign requirements, and the plate geometry enables the heat exchangers to achieve the minimum required efficiency with the least possible pressure drop. Plus, it is much cheaper.

RSK+16 is the unique aluminium counterflow heat exchanger in 366*366 shape. This size offers the lowest pressure drop. A no-compromise solution for demanding users.

The COMBI solution is designed for recovery from larger air volumes. It consists of two REK+ or REC+ counterflow heat exchangers and two air dividers. The use of counterflow heat exchangers in the COMBI solution results in greater efficiency than with commonly used crossflow heat exchangers, which are also commonly employed for higher flow rates above 5,000 m³/h.

BYPASS is suitable for situations where heating the air would be inconvenient, e.g. during summer months when interior heating is not desirable. It is useful in winter as well, since it prevents the heat exchanger freezing (which could easily damage it) when temperatures are below zero.

The RECUTECH galvanized bypass damper BD is a is a control and shut off damper. The product is intended for volume control of supply or extract air. It comes in a manual or motorized version with an integrated optical position indicator. Its control is on the side. The damper length can be ordered in 1 mm increments from 400 mm to 1350 mm. The blades are 100 mm wide.
