SVL Is Pleased to Announce Representation of Oxygen8’s Energy Recovery Units. Energy recovery systems help you maintain a comfortable relative humidity in your indoor environment by transferring the moisture from humid outdoor air to the exhaust airstream or adding moisture to the incoming ventilation air. A pump circulates water between the two. An energy recovery wheel conditions the air that comes into the structure from the outside using the relief or exhaust air leaving the building. Our custom air handlers are available in many configurations, sizes, capacities and materials built to customer specification. The Enthalpy Wheels are usually made of porous materials to increase surface area which aids in energy transfer. These systems help capture the energy in the airstream that would otherwise be exhausted to the atmosphere and use it to either pre-heat or pre-cool the outdoor airstream, depending on the season. We are focused exclusively on designing and manufacturing high-quality, energy-efficient air handling systems. If the system brings in 100-percent outdoor air, or is being modified to bring in 100-percent outdoor air with no recirculation, bypassing the energy-recovery device will reduce or avoid Energy Code. RenewAire Energy Recovery Ventilation (ERV) enhances indoor air quality via balanced ventilation with energy recovery which reduces otherwise wasted energy.
