Tecumseh ak176at-037-j7 Low Back Pressure Reciprocating Compressor R404 R507 1/2 Hp 2500 Btu

Product Description

The Tecumseh AK176AT-037-J7 is a low back pressure reciprocating compressor built for commercial refrigeration systems. It runs on R404A and R507 refrigerants, making it a strong fit for medium and low temperature refrigeration applications. This compressor operates at 1/2 HP and delivers 2500 BTU of cooling capacity. It is designed for both 115V single phase 60Hz and 100V single phase 50Hz electrical supply, giving technicians flexibility for North American and international installations. The base model designation is AKA2425ZXA, which is useful when cross-referencing OEM replacement compressors. The AK176AT-037-J7 uses a high start torque motor, classified as HST, which helps the unit start reliably under load. This is especially important in refrigeration systems where line pressure may not equalize before startup. The motor type is CSR, meaning capacitor start with run capacitor, and it includes both a start capacitor and run capacitor in the package. A potential relay handles the switching function. The suction line connection is 3/8 inches ODF sweat, and the discharge line is 1/4 inches ODF. These are standard sizes for low back pressure compressor circuits. The evaporating temperature range runs from negative 40 degrees Fahrenheit to 10 degrees Fahrenheit, covering a wide band of low temperature and medium temperature refrigeration applications such as reach-in coolers, display cases, and walk-in freezers. The compressor uses polyolester oil with a viscosity of 32 and comes pre-charged with 512 cc of oil. Fan cooling keeps the motor and compressor shell within safe operating temperatures during continuous duty cycles. The unit weighs 45 pounds and has physical dimensions of approximately 8.921 inches in height, 10.579 inches in length, and 7.298 inches in width. Mounting hardware, grommets, and a terminal cover are all included. Agency approval is CURUS, confirming compliance for US and Canadian installations. This unit ships as a single packaged compressor, ready for field installation by qualified refrigeration technicians.
