FreshAIR is a heat recovery ventilation unit that uses the principle of refrigeration to heat or cool ventilation air using exhaust air as a heat sink or source. Since exhaust air temperatures are typically cooler than ambient air temperatures in the summer, the efficiency of FreshAIR can exceed that of a conventional air-cooled system. In winter months, FreshAIR can achieve a COP greater than 5, making it more cost efficient than heat derived from fossil fuels. Both exhaust and supply air streams remain completely isolated, making it an ideal system for recovering energy from contaminated exhaust air.

Built for Service

Other commercial or industrial units are built as throwaway units or are so hard to service that it is easier to just replace the unit. All AIR units are designed and built with the service technician in mind. We are able to do this by take the learning and difficulties that we see in the field and pass that information to our engineering team to enhance our units.

1. Cabinet doors removable for service, without tools.
2. Electrical box positioned for easy access.
3. Serviceable compressors for industrial reliability.
4. Replaceable filter drier with isolation service valves.

Heating Mode

1. Heat is extracted from the evaporator in the exhaust air

2. The compressor upgrades the heat and rejects it to the supply air through the condenser
