Tecumseh AJ 4480 P-FZ (Old Code: CAJ 9480 Z) 3/4 Hp R-404A Refrigeration Compressor

Tecumseh CAJ 9480 Z, one of the most robust examples of French engineering in the commercial refrigeration sector, is now entering the field with the code AJ 4480 P-FZ following the global model update. Our checks have confirmed that, as you may have guessed, this code change is for naming purposes only and that the compressor's power, connection and size specifications are fully preserved to the original standards. The uninterrupted power you look for in commercial display sections, cold rooms and dairy cabinets continues in this legend with its new code.

Wide Operating Range and Eco-Friendly Refrigerant Compatibility

Offering an extremely flexible operating range from low to medium/high evaporating temperatures (-23.3°C to 12.8°C), this model has a 3/4 HP (0.56 kW) motor. In addition to R404A, it also works fully compatibly with new-generation refrigerants such as R507, R449A, R448A and R452A, making your system ready for future regulations. With a cooling capacity of 1080 Watts (3,690 BTU/h) at -10°C evaporating conditions, reaching up to 4,478 BTU/h depending on the condensing conditions, it removes heat from the space tirelessly.

Installation and Service Note for Field Refrigeration Technicians

Technician's Note: Rest assured about the "AJ 4480 P-FZ" label on the new box; it will fit one-to-one onto the valves and mounting points from which you removed the CAJ 9480 Z motor in the old system. While operating with a 15.2 cm³ cylinder volume, this unit can draw high running currents; therefore, when connecting your contactors and overloads, remember to leave a margin based on the unit's maximum continuous current of 8.5A. POE oil soaks up atmospheric moisture like a sponge, so you must evacuate the system perfectly and must not charge refrigerant without fitting a new filter drier. When installing the valves (1/2" and 5/16"), make sure the threads and teflon gaskets do not bind.
