Tecumseh AJ 2464 P-FZ (Old Code: CAJ 2464 Z) 1.5 Hp R-404A Refrigeration Compressor

The legendary 1.5 horsepower low temperature refrigeration compressor CAJ 2464 Z from Tecumseh of France, known for its power in commercial and industrial refrigeration systems, is now offered for sale under the stock code AJ 2464 P-FZ following the brand's global product update. This code change is for naming purposes only; the housing dimensions, valved connection structure and legendary thermodynamic performance of the unit remain exactly the same. Our technicians in the field can safely install this new model in place of the old compressor on a "drop-in" basis, without any modification.

1.5 Hp High-Capacity Low Temperature (LBP) Performance

Designed for industrial freezer rooms, large-volume commercial refrigerators and refrigeration systems operating under heavy conditions, this model has an impressive motor power of 1.5 HP. With its 34.5 cm³ displacement, it offers one of the largest displacement capacities in its class, circulating the R-404A refrigerant in the system with excellent momentum. Even under the demanding conditions of -10°C evaporating and 45°C condensing, it produces 1266 Watt cooling capacity and quickly brings the space down to the targeted sub-zero temperatures.

Installation and Maintenance Note for Refrigeration Technicians in the Field

Technician Note: When the box you receive says "AJ 2464 P-FZ", do not think the wrong unit has arrived; this motor is exactly the new production series of the CAJ 2464 Z. Since it operates at a high power of 1.5 HP and a displacement of 34.5 cm³, the initial starting and continuous running currents (amps) it draws from the mains are high. For this reason, always check the current ratings of the contactors and thermal overload switches in the electrical panel against the compressor's label. When connecting the 5/8" and 3/8" rotalock valves, make sure the system has been cleared of old oil/acid residues and that the evacuation has been carried out completely. Take care not to crush the Teflon gaskets on the valves by applying excessive force when tightening.
