Paul Mueller Company

Self-Contained Air Refrigeration Unit

We introduce the large horsepower self-contained air-cooled refrigeration units. These units are delivered to 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 a 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 off your milk flow. Real-time milk temperatures sensed by the Mutli-Stage Chiller Control engage only the units necessary to preform your cooling at that specific moment.
