Remanufactured Compressors

Remanufacturing Process

  1. The oil is drained from the compressor and properly disposed of.
  1. The compressor is then disassembled to bare casting. Each casting is inspected for   visable   defects and cracks. The castings in good condition are cleaned and de-rusted to bare metal.
  1. The crankcase is visually inspected for integrity of gasket surfaces and threaded holes.
  1. All critical compressor parts, including bearings, inserts, seals, piston rings, suction and discharge valves, are discarded and replaced with new items.
  1. The valve plates are replaced with new ones or reground to ensure good valve seating.  All valve plates are reassembled with new reeds and springs.
  1. The crankshaft, pistons, rods and liners are cleaned and checked to ensure they meet   the  current OEM tolerances. If a component does not meet the tolerances specified,  it is replaced with a new part.
  1. Cylinder holes are inspected for physical damage. Then, the cylinders are dimensionally  inspected and re-honed to OEM specifications in order to ensure proper  seating of new rings.
  1. When upgrading the motor, the stator is electronically tested. A malfunctioning stator is charred under controlled temperatures, rewound, immersed in clear varnish, and retested. Additionally, the rotor is surge rested and evaluated to guarantee initial start up under load.
  1. The oil pump is also visually and dimensionally inspected, upgraded, reassembled, and tested to ensure compliance with specifications for oil flow and pressure.
  1. The compressor is reassembled, with all the bolts torqued to specifications. Immediately after the assembly each compressor is sealed with blank-off plates, charged with nitrogen, and leak tested. The technician repairs any leaks identified during the test.
  1. After passing the leak test, the compressor is recharged. Every compressor we remanufacture is run tested under load to ensure proper oil pressure, amperage, loading, unloading and pump-down capabilities.
  1. Careful work records, including work and test sheets are prepared throughout the remanufacturing process.


During the remanufacturing process our technicians use product data sheets to determine proper tolerances, torques and operating specifications for each compressor.

New and recycled compressors parts are used in an effort to save energy and deliver more ecologically friendly products. The use of recycled compressor parts is not uncommon as long as those items meet or exceed the current OEM tolerances. Advanced Hermetics guarantees our product with a 18* month limited warranty.
