NIBE DVC 10-50L Heat Recovery Unit

Description

NIBE DVC 10-50L is a modern decentralized ventilation unit with heat recovery, often referred to as a mini-FTX system. The unit is specially developed to ensure continuous, healthy and energy-efficient air exchange in individual rooms without requiring extensive ventilation pipes or interventions in the building structure. The model is equipped with an extended telescopic wall pipe, making it ideal for installation in thicker exterior walls.

Function and heat recovery

The ventilation unit works with a reversing fan and an integrated ceramic accumulator core. During an operating cycle of approximately 70 seconds, the unit sucks out heated room air, whereby the heat energy is stored in the ceramic heat exchanger. The fan then automatically reverses its direction of rotation and sucks in fresh outdoor air for a further 70 seconds. The cold outdoor air is effectively preheated as it passes through the warm ceramic core before being supplied to the room. This technology provides a heat recovery rate of up to approximately 85 to 90 percent, which significantly reduces ventilation losses and contributes to lower heating costs compared to conventional natural ventilation or passive fresh air valves.

Adapted for thicker wall constructions

The designation L indicates that the NIBE DVC 10-50L is supplied with an extra-long wall pipe. This telescopic penetration pipe allows for easy installation in external walls with a thickness of up to 700 millimeters. The flexible telescopic construction makes it easy to adapt to the actual dimensions of the wall and provides a stable, weatherproof connection between the inner part and the external facade grille.

Clean and healthy indoor air

The unit is equipped with integrated dust filters and particle filters of class G3 on both supply and extract air. The filters effectively capture pollen, coarse dust, insects and other airborne particles, which creates a pleasant and healthy indoor environment. The filters are easily accessible and can be easily cleaned or replaced during regular maintenance.

Control and interconnection

The unit is conveniently controlled via a discreet control panel on the side of the indoor unit or using the included wireless infrared remote control. Several units can be interconnected in a common system to create balanced ventilation in the home. When paired, the units are set to cycle in opposite phases, which means that one unit supplies supply air while the other diverts exhaust air. This maintains an optimal air balance and prevents pressure differences between rooms.
