Energy recovery systems are designed to capture and repurpose energy from various ventilation and industrial processes to improve the overall efficiency of buildings and reduce energy consumption.
Companies like DRI specialize in energy recovery technologies that integrate into HVAC and ventilation systems to transfer energy between exhaust and incoming air streams. These systems aid in efficiently maintaining indoor air quality while minimizing the energy required for heating or cooling. This is accomplished through the recovery of thermal energy from exhaust air.
By leveraging these systems, industries and commercial buildings can significantly cut utility costs and enhance sustainability through reduced carbon emissions.
Mojave Energy Recovery Systems
Mojave’s ArctiDry is an innovative, next-generation liquid desiccant air conditioner and dehumidifier that can reach dewpoints as low as 35°F without the need for reheat. It offers the option to operate in heat pump mode as low as 10°F ambient, with supplemental heating options, including gas, electric, and hot water. AcrtiDry is easy to operate and maintain, and is installed like conventional packaged HVAC equipment.
