Tecumseh ak172at-038-j7 3/4 Hp Fan-cooled Refrigeration Compressor

Product Description

The Tecumseh AK172AT-038-J7 is a 3/4 horsepower fan-cooled hermetic refrigeration compressor built for commercial and light commercial refrigeration applications. Tecumseh is a globally recognized manufacturer of compressor technology, and this unit reflects that standard of reliability. The AK172AT-038-J7 uses a Capacitor Start-Run (CSR) motor type paired with a High Start Torque (HST) motor, making it well suited for systems that require dependable startup performance under load. A potential relay controls the start capacitor, and an external overload protects the motor windings from thermal damage during abnormal operating conditions. HVAC and refrigeration technicians will find this compressor compatible with a range of low-temperature and medium-temperature refrigeration systems. The evaporating range runs from 0 degrees Fahrenheit to 50 degrees Fahrenheit, covering a broad spectrum of walk-in cooler, reach-in case, and commercial refrigeration system requirements. The unit operates on a dual voltage frequency of 50Hz and 60Hz. At 60Hz, the voltage range is 103 to 127 volts, and at 50Hz the range is 90 to 110 volts, offering flexibility for various power supply environments. The suction line connects via a 3/4 inch Rotolock fitting, while the discharge line measures 1/4 inch. Oil charge is 512 cc of Polyolester oil with a viscosity of 32, which is the correct lubricant choice for use with HFC and HFO refrigerants common in modern refrigeration systems. The compressor displaces 22.599 cubic centimeters and draws a rated load amperage of 11.9 amps at 60Hz, with a locked rotor amperage of 68 amps. The unit weighs 43 pounds and measures approximately 8.954 inches in height, 11.157 inches in length, and 7.298 inches in width. Mounting parts, a terminal cover, grommets, a run capacitor, and a start capacitor are all included. Agency approvals cover cURus standards. This compressor ships in multi-unit packaging and is a direct replacement option for technicians sourcing Tecumseh reciprocating compressor components.
