Mueller® self-contained, air-cooled refrigeration units arrive at the dairy ready to make money. Save days of soldering accumulators, receivers, and remote condensers. These self-contained units, coupled with Mueller Fre-Heaters® and an LS series chiller, are a cooling force to be reckoned with. Driving this packaged chiller system is the Mueller Multi-Stage chiller control. Set the unit to cycle on and off based on your milk flow. Real-time milk temperatures sensed by the Mutli-Stage chiller control engage only the units necessary to perform your cooling at that specific moment.
