Tecumseh AJ 2446 P-FZ (Old Code: CAJ 2446 Z) 1 Hp R-404A Refrigeration Compressor

The CAJ 2446 Z model from the French-origin Tecumseh compressor family, which has proven its quality for years in industrial and commercial low temperature refrigeration systems, is now in the field under the code AJ 2446 P-FZ as part of the brand's global production standards. This update is only a naming change; it makes no mechanical difference to the power, dimensions or valved connection fittings of the unit. If you are looking for an original, long-lasting and efficient solution for your professional refrigeration systems, this new-generation coded motor is exactly the equipment you are looking for.

1 Hp Low Temperature Refrigeration Performance and 26.2 cm³ Displacement

It is designed specifically for demanding conditions requiring "low temperature" (LBP) refrigeration, such as medical coolers, food storage warehouses and commercial freezers. Thanks to its 1 HP motor power and large 26.2 cm³ displacement, it establishes an excellent thermodynamic balance with R-404A refrigerant. Producing 982 Watt cooling capacity at -10 ºC evaporating and 45 ºC condensing conditions, it removes heat from the system quickly and stably.

Installation and Safety Note for Refrigeration Technicians in the Field

Technician Note: When you open the new box, do not be misled by the "AJ 2446 P-FZ" marking on the label; this motor is identical to the legendary CAJ 2446 Z that the years could not wear out, and fits the old chassis as a "drop-in" replacement. When working on low temperature refrigeration systems, keep the evacuation process longer than for standard cabinets for the safety of the compressor. When connecting the 1/2" suction and 5/16" discharge valves of this powerful 26.2 cm³ motor to the system, you can prevent gas leaks by renewing the Teflon gaskets and tightening the valves evenly. Always take care to use the original overload protector and relay assembly on this electrically operated unit.
