This whole-house EC energy recovery ventilator delivers balanced fresh air, lower thermal loss and efficient EC motor control for residential and light commercial projects.
EC Energy Recovery Ventilator delivers balanced whole-house ventilation for residential and light commercial projects: it supplies fresh outdoor air while exhausting stale indoor air, and the heat recovery core transfers energy between the two streams to reduce heating and cooling loss.
The EC motor provides variable-speed control, which keeps operation efficient and quieter across partial-load conditions. With models ranging from 90~180 m³/h up to 480~800 m³/h airflow, the series covers compact homes through larger whole-house and project installations.
Designed for dependable whole-house recovery ventilation with efficient motor control, recoverable thermal energy and simple installation.
EC motor with variable speed adjusts airflow to demand, lowering power use and noise during partial-load operation.
Heat exchange rates up to 82% in heating mode help keep indoor comfort stable while reducing energy loss.
Washable or replaceable filters block dust and pollutants while the unit runs continuous fresh-air supply.
31–41 dB noise range across the model line supports residential and low-noise project environments.
Compact unit size with straightforward installation and wiring for retrofit and new-build projects.
Six models from CHQR-180EC to CHQR-800EC with Ø100–Ø200 mm duct options for different project layouts.
