E-Star OE Condensing Unit

A variety of upgraded features, including a Copeland® scroll compressor, a variable-speed fan, rifled condenser tubing, and a subcooling coil, make Mueller® E-Star® OE condensing units the most energy-efficient and cost-effective refrigeration system available. The user-friendly design of Mueller E-Star OE units lets you access electrical controls and valves with ease. An oil sight glass and fill port allow you to monitor and change refrigerant oil and meet future refrigerant requirements. Mueller condensing units outperform all other refrigeration units in terms of reliability, efficiency, and value.

Features

  • A proprietary accumulator heat exchanger maximizes refrigeration capacity while protecting the compressor from liquid refrigerant
  • A quiet, energy-efficient Copeland "ZB" scroll compressor, designed for commercial refrigeration service rather than air conditioning, provides improved performance over the entire cooling temperature range
  • Scroll technology is more energy efficient and has fewer moving parts than reciprocating compressors
  • A custom tube-and-fin condenser with rifled tubing and integral subcooling loop maintains subcooled liquid refrigerant to the thermal expansion valve, ensuring maximum evaporator efficiency
  • A single, variable-speed, high-efficiency fan motor provides maximum condensing efficiency over a wide range of ambient temperatures 
  • E-Star OE is available for use with both R-448a, R-507, R404a, R407a, R407c, and R407f
  • ElectroFin® protective coating enhances the durability of the unit 
  • Oil sight glass, oil fill/drain port, and screw electrical terminals are added bonuses that ensure long-term reliability and serviceability
  • Rust-resistant brass service valves are located in front of the unit for easy access without removing a cover
  • An electrical enclosure is designed for safety, ease of installation, and serviceability
  • A resistive compressor crankcase heater is included for reliable operation during colder ambient temperatures.
  • A heavy-duty, galvanized three-piece steel cover with an attached steel grill encloses and protects the unit, and provides safe operation
