• The SEMCO Unitary Wheel Cassette (UWC) Series, a sensible and latent energy recovery aluminum desiccant wheel, is designed and packaged as the HVAC industry’s first drop-in replacement for polymer desiccant wheels in most unitary ERV brands.

    The UWC Series’ 3-3/4-inch-wide (100-mm) wheels feature a fast-acting, corrosion-resistant, proprietary desiccant that’s applied to a sturdy, but lightweight all-aluminum wheel substrate. The honeycomb matrix’s fluted opening design efficiently produces maximum latent and sensible air-to-air heat transfer, but generates up to 50-percent less HVAC system static pressure than polymer film wheels.

    Besides assisting buildings in surpassing ASHRAE 90.1 building energy compliance, the aluminum wheels also have longer life cycles and vastly less periodic maintenance requirements than polymer wheels and can withstand temperatures of up to 180°F.
