E-Star® Refrigeration Units

In the mid 1990’s Mueller set out to build the perfect dairy farm condensing unit. After years of development and testing The Milk Cooling Systems Specialist™ was ready to present this cooling machine to the dairy industry. When the first E-Star rolled off the production line in 1998 no one really knew the impact it would have on the dairy industry. As technology has advanced so has the E-Star. It is now 2015 and the E-Star has never been better!

The Digital Copeland® Scroll compressor is now in the driver’s seat of this new and improved E-Star. This digital technology allows a reduction in compressor capacity when it is not needed, lowering electricity consumption, ultimately reducing energy bills. But when you are milking your high group the E-Star will be ready to throttle up to 100%. Imagine automatically transitioning from a Prius to a Peterbilt based on your driving parameters.

• Most Energy Efficient System on the Market - Proprietary electronic subcooling valve and control completely flood the milk cooler evaporator for maximum operating efficiency.

• Copeland® Scroll Compressor Design - A refrigeration compressor designed to handle the large temperature changes required to cool milk. Scroll technology is more energy efficient and has less moving parts than reciprocating compressors.

• Maximum Evaporator Efficiency - Condenser subcooling coil ensures subcooled liquid refrigerant, ensuring maximum evaporator efficiency.

• Enhanced Condenser Heat Transfer Surface - Enlarged tube-and-fin condenser with rifled tubing results in greater refrigeration capacity and efficiency.

• Suction Line Accumulator Heat Exchanger - Increases system efficiency and protects compressor during low load conditions.

• Longer Compressor Life - Screw terminals versus push-on terminals, which provide positive electrical connections and reduces compressor failure.

• Single, Variable-Speed Fan with High-Efficiency Motor - Maintains an even air flow to increase capacity and efficiency of the compressor.

• Greater Serviceability - Electrical compartment located in the upper front portion of the unit permits easy service access.

• Alternate Refrigerants - HiPerForm is available for use with the environmentally friendly HFC-507.

• Oil Sight Glass and Fill Port - Allows simple inspection of the compressor oil level and provides an easy method to add or change oil for future HFC refrigerant requirements.

• Rust-Resistant Brass High- and Low-Side Valves - Located in front of the unit for easy service access without removing the cover.

• Galvanized Three-Piece Cover - Heavy-duty metal enclosure protects the unit from the environment while providing safe operation. The three-piece construction provides easy service access.
