Comfort 250 Top is an energy-efficient MVHR unit, designed for homes with a ventilation requirement of up to 250 m3/h. Comfort 250 Top is only available for project sales.
Comfort 250 Top is equipped with a unique boost function intended for cooker hood operation. Upon user activation, an additional 50 m3/h is provided to ensure proper suction in the cooker hood. Through the boost function, Comfort 250 Top can deliver 300 m3/h at 200 Pa external pressure loss.
The unit is designed for top connection and has a very low noise level, allowing for indoor installation. Comfort 250 Top is a ventilation system with compact dimensions, enabling it to be installed in a 60 cm wide cabinet. The control panel is integrated into the front, eliminating the need for additional mounting. However, it is possible to detach the panel.
Comfort 250 Top is constructed to achieve low power consumption and high heat recovery. This combination results in an energy efficiency rating of A.
Comfort 250 Top is also available in a Polar version, which is equipped with a self-regulating preheating element. The preheating element protects the unit in cold outdoor temperatures by heating the supply air and preventing frost formation in the heat exchanger.
The CTS400 is a simple and intuitive control panel with a complex control system that contains many useful functions.
