Compact wall-mounted HRV100 heat recovery ventilator

Heat Recovery in Practice – No Ducts, No Complex Installation

The device recovers heat from the exhaust air leaving the room and transfers it to the fresh air entering from outside. Thanks to the aluminum regenerative heat exchanger – a material with high thermal conductivity – energy is not lost but transferred. The temperature of the supplied air approaches the indoor temperature, and heat losses are significantly reduced – without the need to upgrade the ventilation system.

Operation in 60-Second Cycles – Automatically and Silently

The heat recovery unit always starts in exhaust mode: air from inside flows through the aluminum heat exchanger, transferring heat to it. After 60 seconds, the fan automatically switches to supply mode – fresh air from outside passes through the same heat exchanger and is warmed by the stored energy. The process repeats. No manual control is required – everything operates automatically in the background, without disturbance.

Two Operating Speeds – Control Over Airflow

The ability to choose between low and high speeds allows ventilation to be adapted to specific needs. On low speed (32 dB), the device operates quietly – ideal for bedrooms or living rooms. On high speed (36 dB), it provides greater airflow – useful after bathing, during cooking, or when more people are present in the room. Speed switching is performed via a pull cord located on the front of the device – simple, requiring no additional controls or electrical connection.

Wall-Mounted Installation – Ready to Install in 15 Minutes

The device is mounted directly into the external wall, without the need for ductwork or connection to drainage. Hole diameter: 100 mm. The telescopic ventilation duct (adjustable from 33.5 to 54 cm) adapts to wall thickness. Mounting height: minimum 2.3 m above the floor. A downward slope of 2–5° towards the outside ensures condensate drainage – the device does not require a water drain.

Low Energy Consumption and Long-Term Reliability

Power consumption: 1.5 W on low speed, 2 W on high speed. The ball-bearing motor operates quietly and has a long service life – even during continuous operation. IPX4 protection rating guarantees moisture resistance – proven in bathrooms or kitchens. The entire unit is made of ABS – resistant to mechanical damage and UV radiation.
