The Residential Heat Recovery Couterflow units RHR-CF are high efficiency ventilation units with heat recovery and are designed for residential ambiences.

If a pre-heating coil is required only after the unit has been purchased, a circular electric heater accessory for duct application is available for each unit.

The electric heater technology has been selected and developed for typical HVAC applications. Armoured electric duct heaters have been used (single phase 230Vac - 50Hz power supply). The electric heater is equipped with all the required safety measures and is regulated through a modulated pulse width signal generated by the central PCB in response to operation of the PID controller.
