Decentralised ventilation from Glen Dimplex to improve the air quality image

Decentralised ventilation. Simply efficient. Directly through the wall.

You are looking for a simple solution to improve the air quality in your rooms. Especially if you have carried out a major renovation or have completed a new-build property. If so, you can simply lay the ventilation system through the wall.

Decentralised ventilation systems.
No more mould due to incorrect ventilation.

Decentralised ventilation systems from Glen Dimplex are simple to install in individual rooms as a targeted means of improving the room air quality. They require no air distribution system and are therefore particularly well suited for retrofitting or renovating existing buildings.

Dezentrales Lüftungssystem DL 40


Ein gutes Raumklima bei niedrigen Energiekosten: Für Neubau und Sanierung sind kontrollierte Wohnraumlüftungen die richtige Wahl. Der Vorteil einer dezentralen Lüftungsanlage liegt im geringen Platzbedarf und der einfachen Installation. Das DL 40 eignet sich optimal für den nachträglichen Einbau in der Sanierung. Die kontrollierte Wohnraumlüftung transportiert überschüssige Feuchtigkeit nach außen und schützt so die Bausubstanz.

The installation.
Simply uncomplicated.

The compact design of the units makes installation and subsequent maintenance extremely easy. Other than an electrical connection, all that is needed for installation is a straight wall opening or for a hole to be drilled in the external wall of each room.

This makes decentralised ventilation systems particularly interesting for renovations of old buildings. They are also perfect for use in new-build properties, if no ventilation ducts have been included in the plans.

And what about aesthetics? Design panels from GDD set high-quality accents in the room and can be easily coated in the colour of the wall.

Genuine heat recovery.
With cross counter flow heat exchanger.

The heat in the exhaust air is recovered continuously and extremely efficiently. 

This enables a real heat supply rate of up to 87%.

You almost couldn’t get any quieter.

Intrusive noises remain outside, but the ventilation itself is almost silent during operation.

The decentralised ventilation systems from Dimplex feature amongst the quietest units on the market and offer the best sound penetration values in exterior wall openings.
