Semco LLC showcased its Unitary Wheel Cassette (UWC) Series, a sensible and latent energy recovery aluminum desiccant wheel. The UWC Series is designed and packaged as a drop-in replacement for polymer desiccant wheels in most unitary energy recovery ventilation (ERV) systems. The UWC Series’ 3 ¾-inch-wide (100-mm) wheels feature a fast-acting, corrosion-resistant, proprietary desiccant applied to a strong but lightweight, all-aluminum wheel substrate. The honeycomb matrix’s fluted opening design efficiently produces maximum latent and sensible air-to-air heat transfer while generating less HVAC system static pressure. Besides assisting buildings in surpassing ASHRAE 90.1 compliance, the aluminum wheels also have long life cycles, are designed for minimum periodic maintenance, and can withstand temperatures of up to 180°F.
