ComfoAir Q450 PL R VV ST right-hand version Heat recovery ventilation unit 450 471502074

Heat recovery ventilation unit – comfort and energy saving

The Zehnder ComfoAir Q450 PL R VV ST ventilation unit is an advanced solution providing a constant supply of fresh air and heat recovery, which translates into thermal comfort and reduced heating costs. The device is designed for both new and modernized buildings, offering a performance of up to 450 m³/h at 200 Pa.

Intelligent solutions for a healthy climate

The key element of the unit is a high-efficiency cross-countercurrent heat exchanger with 25% more surface area than standard solutions available on the market. This ensures maximum heat recovery from the exhaust air, minimizing energy losses. Additionally, a modulated pre-heater (VV) and bypass adjust the device's operating parameters to current weather conditions, ensuring optimal air temperature regardless of the season. Built-in temperature, humidity and air flow sensors automatically regulate the system's operation, maintaining constant user comfort.

Quiet operation and ease of use

The unit is equipped with the quietest fans on the market (with appropriate certification), making its operation almost inaudible. The intuitive control panel on the housing allows easy device management. It is also possible to expand the system with additional control modules – ComfoSwitch C, ComfoSense C, ComfoConnect LAN C, KNX and Option Box (GWC, 0-10V) – allowing for full integration with a smart home system. Fixed connection ports (ST) facilitate installation and ensure leak-proof connections. The device is available in a right-hand version (R), with the possibility of conversion to a left-hand version (L), which increases installation flexibility. It can be mounted on both the wall and the floor.
