Model YVWA utilizes variable-speed technology to help cut energy costs and carbon emissions. The variable-speed drive saves energy during the 99 percent ofJohnson screw chiller operating hours spent at off-design conditions when tower-water temperatures are lower. It increases sustainability by using HFC-134a refrigerant, which has zero ozone-depletion potential. Its proprietary falling-film evaporator reduces the chiller’s refrigerant charge.
