VME II modular chillers provide superior full- and part-load efficiency—and free cooling during cold weather. VME II is up to 30 percent more efficient during simultaneous heating and cooling, and eliminates multiple reversing valves (for an additional three-percent efficiency gain) and associated control complexity. The VME II control algorithm automatically matches chiller module capacity to the building heating and cooling load requirements by closing and/ or opening VME valves for best operation, maximum efficiency, lower energy costs and a smaller carbon footprint. DHRC™ modules in VME II applications can provide up to 122 degrees of water temperature lift with a single compression cycle compared to only 86 degrees of lift with heat pumps, in heating mode.
