Decentralized HRU

DYREC DUO 150 Silent is the innovative decentralized HRU with heat recovery up to 90%. Suitable for any  kind of rooms and ideal for a coupled installation to optimize the system efficiency.

It differs from the DYREC Duo 150 series due to its high acoustic insulation (D n,e,w : 45 dB) obtained thanks to the soundproof, windproof outer cover.

The cover, specifically designed to reduce noise from outside, is fitted with a fireproof soundproofing mat and is made of stainless steel sheet 304 with a front inspection panel and anti-insect net.

Easy Installation and maintenance:
– Magnetic coupling/uncoupling of the unit.
– ø 150
– Telescopic duct.

Suitable for walls with thickness from 340 to 500 mm (adaptable to other wall thickness from 250 to 1000 mm).

DYREC Duo 150 Silent is a “push-pull” HRU with reverse flow. It  is provided with a ceramic heat exchanger that accumulates the heat from the extracted air during the “pull” cycle andreleases it to the new fresh air during the “push” cycle.

It is designed for a 24 hrs running at the minimum speed. The unit switches to the extraction operation modalitywhen speed boost is activated manually (through remote switch or remote controller RLS available as accessory) or automatically through the humidistat for versions DYREC Duo Silent MHY and DYREC DUO Silent RC.
