E-Star® Refrigeration Units -

A variety of upgraded features including a Copeland® scroll compressor, a variable-speed fan, rifled condenser tubing, and a sub-cooling coil makes Mueller refrigeration units the most energy-efficient and cost effective refrigeration system available for the dairy industry.

Mueller E-Star units are designed for easy service. Electrical controls and valves are located for easy access. There's even an oil sight glass and fill port that allow you to change refrigerant oil to meet future HFC requirements.

Mueller refrigeration units outperform all other milk-cooling units in terms of reliability, efficiency, and value. It's what you'd expect from The Milk Cooling Systems SpecialistsTM.

• 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 maintains liquid refrigerant, ensuring maximum evaporator efficiency.
• Enhanced 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 access.
• Alternate Refrigerants - HiPerForm is available for use with the environmentally friendly HFC-507.
• Oil Sight Glass and Fill Port - Allows refrigerant oil to be easily changed for future HFC refrigerant requirements.
• Rust-Resistant Brass High- and Low-Side Valves - Located in front of the unit for easy access without removing the cover.
• Galvanized Three-Piece Cover - Heavy-duty metal encloses and protects the unit for safe operation while three-piece construction provides easy access.
• Quality Assured - Meets worldwide standards such as CSA and CE.
