Tecumseh ak163at-038-j7 1/2 Hp R-12 Reciprocating Compressor Commercial Back Pressure AKA9441AXA

Product Description

The Tecumseh AK163AT-038-J7 is a 1/2 HP reciprocating compressor designed for commercial back pressure refrigeration applications. It is built to operate with R-12 refrigerant and runs on 115V at 60Hz or 100V at 50Hz, making it suitable for a range of commercial refrigeration systems. This unit is also cross-referenced as AKA9441AXA. HVAC and refrigeration technicians working on commercial display cases, reach-in coolers, and similar back pressure equipment will find this compressor a reliable replacement or service part. The AK163AT-038-J7 delivers 4100 BTU per hour of refrigeration capacity under ASHRAE test conditions at 115V and 60Hz. Input power draw is 800 watts, giving it an efficiency rating of 5.13 BTU per watt-hour. The evaporator temperature is rated at -6.7 degrees Celsius (20 degrees Fahrenheit), with a condensing temperature of 54 degrees Celsius (130 degrees Fahrenheit). The compressor uses a CSIR motor type with high start torque, which helps it start reliably under load. It is fan-cooled for consistent thermal management during continuous commercial use. The overload protection is external, and it uses a current relay for motor protection. The unit carries CSA Listed and UL Recognized agency approvals, confirming it meets North American safety and performance standards. The displacement is 22.599 cubic centimeters. It uses synthetic alkylate oil with a viscosity of 32 cSt and an oil charge of 453 cubic centimeters. Locked rotor amps are rated at 58.8, and rated load amps at 60Hz are 9.2. This compressor is a direct-drive, single-phase unit built for the demands of commercial refrigeration service work.
