New Project – Maximum Performance in Minimum Space!

This time we faced a truly extreme challenge – the unit had to fit into an exceptionally tight space.
The requirements were clear: all four ducts upwards, maximum efficiency, and ultra-quiet operation.

We went for an unconventional solution: the fans were placed behind the heat exchanger, where there was the only available space.
To prevent the fan impellers from hitting angular surfaces and causing turbulence, the inner casing around the rotors was aerodynamically shaped into a teardrop form.
This ensures smooth airflow, minimal pressure losses, and remarkably quiet operation.

Filtration as usual – stretched filter textile, so annual filter replacement costs next to nothing.
We used the RECUTECH REK+31 (non-enthalpic) heat exchanger, ensuring high thermal efficiency and long service life.

The result:
A highly efficient, quiet unit at roughly half the price of comparable mass-produced systems.
Technology that makes sense – practical, precise, and built with attention to every detail.
