All HRXE-HERA models have been designed with 100% automatic bypass, listed on the SAP Product Characteristics Database (PCDB).

The HRXE-HERA range operate by continuously extracting moisture-laden air from ‘wet’ rooms within the property whilst simultaneously drawing in fresh, filtered supply air from outside. The heat from the extracted stale air is recovered via a heat exchanger inside the heat recovery unit which becomes tempered and filtered, before supplied into the habitable rooms, creating comfortable and well-ventilated homes.

Other Features

  • The heat exchanger block within these units can recover up to 95% of the normally wasted heat. The two independent fans have full-speed control for background and boost ventilation rates.
  • The HRXE-HERA range has a summer bypass function. In warmer months this function automatically activates to ensure the property is being well-ventilated and comfort levels are maintained in the home by continuously drawing in fresh filtered air into the habitable rooms.
  • Due to its intelligent design, there will be no reduction in airflow when operating in bypass mode resulting in enhanced performance.
  • Designed to provide optimised balanced (supply and extract) mechanical ventilation with heat recovery and both listed on the PCDB.
  • Weight: 20kg.

Models available include

  • HRXE-HERA Standard unit with 100% bypass
