BROAN

Broan energy-recovery ventilators (ERVs) transfer both heat and moisture between incoming and outgoing air streams, while heat-recovery ventilators (HRVs) transfer heat only. In the 3G Electric catalog, ERV models include the B150E75NT and B160E75RT, and HRV models include the B160E65RS and B160E65RT. Both types are available in side-port and top-port configurations, with airflow ratings from 119 to 140 cfm at 0.400 in. SP and up to 80% maximum efficiency. Selection depends on climate: ERVs help maintain indoor humidity in humid or mixed climates, while HRVs are suited to cold, dry climates where moisture retention is less critical.

The Broan ERV and HRV models listed by 3G Electric operate on 120V AC, 60 Hz, single-phase power. They use ECM variable-speed motors and have plug-in electrical connections. This means installation requires a standard 120V AC receptacle near the unit. For applications with different voltage or frequency, a transformer or alternative model may be required. Always verify the nameplate voltage and frequency against the available power supply before ordering.

Broan ERV and HRV units in the 3G Electric catalog offer two defrost types: recirculation and exhaust-only. Recirculation defrost temporarily stops outdoor air intake and recirculates indoor air through the core to prevent freezing. Exhaust-only defrost temporarily shuts off the supply air while continuing to exhaust, allowing warm indoor air to pass through the core. Models with recirculation defrost include the B160E65RS, B130E65RS, B160E75RS, B160E75RT, and B160E65RT. Exhaust-only defrost models include the B150E75NS and B150E75NT. The choice depends on climate severity and installation specifics.

The Broan surface-mount electric ceiling heater (MPN 157) is a fan-forced unit rated 1250W at 120V AC, single-phase. It has a gray finish and measures 2-11/16 in H x 11 in W x 2-3/4 in D. A thermostat is not included, so a separate line-voltage thermostat is required for temperature control. This heater is designed for surface mounting on a ceiling and is suitable for small rooms, vestibules, or spot heating applications where ducted heating is not available.

The Broan ERV and HRV models listed by 3G Electric comply with CSA C439, CSA F326, HVI 2100, UL 1812, UL 94 HF-1, RoHS 2015/863, and Prop 65. These certifications cover performance, safety, and material restrictions. CSA C439 and CSA F326 are Canadian standards for ventilation performance and installation. HVI 2100 is a North American certification for airflow and energy performance. UL 1812 covers safety for ducted air handlers. UL 94 HF-1 relates to flammability of plastic materials. RoHS and Prop 65 address hazardous substances. Compliance documentation is available upon request.

Broan ERV and HRV models are primarily designed for residential ventilation, with airflow ratings from 119 to 140 cfm. They are not intended for large commercial or industrial spaces, which typically require higher airflow capacities. However, they can be used in small commercial settings such as offices, retail spaces, or light-duty applications where the ventilation demand falls within the unit's rated capacity. For industrial processes or large-scale ventilation, alternative equipment with higher cfm and different construction may be necessary. Consult the project specifications and applicable codes to determine suitability.
