Compact unit with side connections.
Designed for supply and exhaust air ventilation with energy recovery.
Suitable for installation in homes, offices and other premises where there are stringent requirements on the indoor environment.
High temperature efficiency 86%, low energy consumption (SFP), low sound level, high operating reliability and provides clean indoor air.
Unique design minimizes all thermal bridges.
Delivered with Siemens Climatix (CX) control equipment.
Comes prepared for Modbus communication via RS485 (accessory needed).
Airflow is generated by two silent anti-vibration plug fans with EC motors and impellers with backward curved blades.
The fans are connected with quick connectors and are very easy to remove for cleaning.
Has a speed controlled rotating aluminum heat exchanger with adjustable hub and purge sector. The rotor can be removed for cleaning.
Filter ISO ePM1 65% as standard, for both exhaust and supply air. The filter is very easy to change.
Available with integrated electric heater or heating coil.
The water and electrical connections are positioned to facilitate practical and simple connection.
The unit is made from aluminum-zinc-plated steel and insulated.
For placement in both warm or cold environments.
Available in either right-hand or left-hand design.
Delivered with adjustable feet and Novibra mats.

NOTE! The warranty of HERU is only valid if accessories/equipment (e.g. filters) from H. Östberg AB are used.
