HVAC Portable Systems
A large 196 ft. diameter, floating-roof tank was scheduled for routine maintenance. The project's scope included taking the tank's structure to a "white blast" and replacing the inner lining. HPSI was called to design a temporary system to control the relative humidity and the tank's skin temperature. HPSI designed a system utilizing HPSI boilers and air handlers to provide 160F air. This solution provided a tremendous cost savings advantage compared to traditional electric heaters and generators typically used in the industry. The boiler/AHU package provided additional heating capacity and cut the cure time from 72 hours to 24 hours.
