Mueller's LS chillers are the world's most energy-efficient milk cooling systems. Used for instant cooling and additional cooling, these chillers are designed for ease of installation and operation. They utilize high-quality Scroll and Discus condensing units, which save energy and reduce electrical costs. The LS and LSA chillers, combined with an Accu-Therm® plate heat exchanger, can be used for either instant cooling or heavy precooling, depending on your dairy's needs.
