Owned by Pinnacle Casino, this 75,000 sq. ft. facility with 200 hotel rooms operates 24/7 through every climate condition. HTS Texas provided Semco custom air handling units with energy recovery to extend equipment life in the smoke-filled environment and to reduce overall project tonnage when a 1,000-ton chiller was removed from the central plant design. This system allows for precise humidity and temperature control and Semco is the only energy recovery wheel to meet the strict City of St. Louis code for air-to-air energy recovery.
