Tecumseh AG133RF-104-J7 Compressor

The Tecumseh AG133RF-104-J7 is a high-capacity hermetic reciprocating compressor engineered for demanding commercial air conditioning and high-temperature refrigeration applications. Operating on 200-230V 3-phase power, this unit delivers a nominal 61,000 BTU cooling capacity specifically optimized for R22 refrigerant systems. As the direct replacement for 21J64, it offers a drop-in solution for legacy hardware, maintaining critical performance parameters like 7/8" suction and 1/2" discharge line sizing. The three-phase motor configuration provides superior torque and operational efficiency compared to single-phase alternatives, making it a standard choice for institutional and industrial HVACR maintenance. Designed for high-back pressure (HBP) environments, this Tecumseh 5-ton compressor ensures consistent mass flow and thermal management. Field technicians must verify oil compatibility and suction line positioning, as mounting footprints may vary slightly from original equipment despite matching displacement and electrical ratings. Heavy-duty internal suspension minimizes vibration and mechanical noise across the duty cycle.

• Direct OEM Compatibility: Serves as the official replacement for 21J64 and AG133RT-003-J7, ensuring simplified field retrofits.
• High-Phase Efficiency: The 3-phase refrigeration compressor design reduces internal heat buildup and improves motor longevity under continuous load.
• Optimized R22 Performance: Specifically valved for R22 and R407C, providing reliable 61,000 BTU cooling capacity for large-scale evaporative coils.
• Rugged Construction: Features a heavy-duty hermetic shell and internal motor protection to withstand the rigors of high-temperature AC cycles.

What refrigerant should be used with the AG133RF-104-J7?
This model is primarily rated for R22 but is also listed for R407C applications. Always verify the existing system oil type when retrofitted to ensure compatibility.

Is this a drop-in replacement for the 21J64?
Yes, the Tecumseh AG133RF-104-J7 compressor is the designated replacement. However, always check the line sizes (7/8” suction, 1/2” discharge) to ensure they match your existing piping.

Does this unit require a start capacitor or relay?
Since this is a 3-phase HVAC compressor, it does not require a start capacitor or potential relay, relying on the third leg of power for starting torque.
