Controls
- 24V dry contacts available for 2-speed control, time-clocks, occupancy and CO sensors also available.
- For units up to NU1600, ES Series controls are available.
Defrost Strategies (-5°C/23°F and colder)
- Fan Shut Down: Supply fan shuts down while the exhaust fan continues to move warm air through the core.
- Damper: A damper closes the OA port and opens a fifth port which brings warm air through the core for a predefined time cycle. The exhaust fan remains on.
Commercial Heat & Energy Recovery Ventilators
- Nu-Air Commercial HRV’s/ERV’s provide fresh air to conditioned spaces while simultaneously exhausting stale air through a cross-flow heat exchanger where energy is transferred from the exhaust to supply air without cross contamination.
- Polypropylene Cores: Sensible temperature effectiveness averages 65-75% in heating season and 20 – 30% in cooling season
- Enthalpy Cores: Sensible temperature effectiveness averages 60-80% in heating season and 50 – 70% in cooling season.
- These efficiencies enable the downsizing of mechanical systems and reduce capital and operating costs.
