Thermo King has enhanced its Spectrum multitemperature and SB-30 series single-temperature refrigeration units with its Smooth Air Blower, an evaporator blower assembly engineered to increase cooling capacity by up to 4 percent and lower fuel usage by up to 7 percent.
The assembly requires 24 percent less power than previous generation blower assemblies due to a more efficient blade design, resulting in a smaller blower assembly. Smoother inlet air means less friction and less energy consumed, resulting in increased capacity. The enhancement now is standard on Spectrum and SB-30 series units, including the SB-130, SB-230 and SB-330.
