The AE/TAJ series features large-displacement, high/medium-back-pressure hermetically sealed reciprocating compressors, specifically designed for commercial refrigeration equipment. Utilizing the eco-friendly refrigerant R404A, these are classic models within Tecumseh's renowned "AE/AJ" series, known for their rugged durability and powerful cooling capacity.
Equipped with a Class F insulated motor and low-slip design, they achieve an ideal balance between high cooling capacity and low energy consumption. The balanced design effectively reduces vibration and noise, making them suitable for long-term continuous operation. Wide voltage adaptability — single-phase operating voltage 180–240V, three-phase voltage 340–440V.
The CAE2446Z/TAJ2446Z delivers 1 HP (0.735 kW) with a weight of approximately 30 kg. In the model designation, "24" indicates a displacement of 2.4 cubic inches (approx. 39.3 cc), which is a relatively large displacement, enabling more refrigerant to be compressed per cycle for stronger cooling performance. Typical applications include commercial refrigerators, display cases, ice cream machines, and kitchen refrigerators in medium evaporation temperature scenarios (-10°C to +10°C).
The CAE2417Z through CAE2432Z models form a power gradient from 7/16 HP to 3/4 HP, suitable for small- to medium-sized commercial refrigeration equipment, such as restaurants and convenience stores requiring 24/7 continuous refrigeration.
Q1: What is the power gradient of the CAE2417Z through CAE2432Z?
A: They form a power gradient from 7/16 HP to 3/4 HP — CAE2417Z (7/16 HP), CAE2420Z (1/2 HP), CAE2424Z (5/8 HP), and CAE2432Z (3/4 HP), suitable for small- to medium-sized commercial refrigeration equipment of different scales.
Q2: Do the compressors in this group require fan cooling?
A: Tecumseh recommends that compressors rated 1/5 HP and above generally require forced air circulation (or an oil cooler) to cool the motor and discharge temperature, in order to maintain reliability, especially in high-temperature environments. For models above approximately 1.5 HP, the suction gas handles about 85% of the cooling task, making superheat control particularly important.
