Copeland ASE20C4E-IAA-901 Compressor

The Copeland ASE20C4E-IAA-901 is a high-performance hermetic reciprocating compressor engineered for medium and high-temperature refrigeration applications. Operating on a 115V single-phase power supply, this 1/4 HP nominal unit delivers a reliable cooling capacity of 2000 BTU. As a precision-engineered OEM replacement compressor, the ASE20C4E-IAA-901 is the direct successor to the legacy ASE20C4-IAA-901 and the ARE43C3-IAA-901 models, ensuring a seamless drop-in fit for existing refrigeration systems. This model is multi-refrigerant approved, providing exceptional versatility with R-404A, R-407C, R-448A, R-449A, and R-452A. Its robust design features polyolester oil (POE) for superior lubrication and protection, and a 54 cu-ft/hr displacement for consistent mass flow. Built for the rigorous demands of commercial foodservice and industrial cooling, this unit utilizes an induction run-capacitor start motor and optimized liquid handling technology to achieve improved EER efficiency compared to previous generations. Contractors can rely on its quiet operation and sweat/braze connections for a secure, leak-free installation in reach-in coolers, vending machines, and display cases.

Key Benefits

• Universal Compatibility: Multi-refrigerant approval allows for use with R-404A, R-448A, and R-449A, reducing inventory complexity.
• Direct OEM Replacement: Engineered as a standard 115V swap for ASE20C4-IAA-901 and ARE43C3-IAA-901 models.
• High Thermal Stability: Charged with POE oil to maintain viscosity and protection across high-temperature refrigeration cycles.
• Enhanced Efficiency: Delivers up to 30% more Energy Efficiency Ratio (EER) than legacy platforms for lower operational costs.

Common Questions

Is the ASE20C4E-IAA-901 compatible with R-22 systems?
While some legacy models supported R-22, this modern unit is optimized for R-404A and newer HFO blends. Always verify the expansion valve and oil compatibility before retrofitting older systems.

Can I use this compressor to replace an ARE43C3-IAA-901?
Yes, the ASE20C4E-IAA-901 is the direct engineering replacement and will match the electrical and physical footprints of that model.

What type of oil does this compressor come with?
This unit is factory-charged with 12 oz. of Polyolester (POE) oil, making it suitable for use with HFC and HFO refrigerants.
