Identified from the nameplate

Ammonia compressor parts

Wrong ammonia compressor parts extend shutdowns. A liner that is “close enough” for a Grasso RC-11 will score a piston in hours. A Mycom seal kit for the wrong frame weeps on the next. We identify from make, model, serial, and a photo of the failed part — then source OEM or high-grade equivalents.

Piston and screw kits we quote most

Piston rooms: pistons, liners, valve plates, connecting rods, crankshafts, gasket sets. Screw rooms: male/female rotors, bearings, mechanical shaft seals, slide valves, couplings, gasket kits. Controls rooms often need sensors and solenoids as well — those go on a separate list so they are not mixed with the mechanical kit.

Searches for “Mycom parts” and “ammonia refrigeration parts” already reach this site. The missing piece is a page that says the part name and the identification method in the title. Send the plate. Do not send “send a piston.”

  • Grasso RC-11, RC-12, V-series piston kits
  • Grasso / GEA screw seal, bearing, and rotor sets
  • Mycom, Sabroe, Howden, Vilter, and York identification
  • Gasket sets and fasteners matched to temperature rating

OEM vs high-grade equivalent

Safety-critical sealing faces and valve reeds should match original metallurgy. Some gaskets and fasteners can be high-grade replacements if dimensions and temperature rating are confirmed. Mixing unknown aftermarket reeds with OEM seats is how a cheap kit becomes a second shutdown.

Pair the kit with the labour. A valve-plate set without torque sequence and alignment still fails. Use the overhaul pages when you need both.

Questions plants ask first

How do I order the correct ammonia compressor part?

Photograph the nameplate (make, model, serial) and the failed part next to a scale. Add running hours and the symptom. That is enough for a first quotation.

Do you stock Mycom and Grasso parts?

We source against the plate. Common Grasso piston and seal items move faster. Unusual Mycom or screw-frame kits are quoted to lead time — still faster than guessing the part number.

Can parts ship outside Pakistan?

Yes. We support UAE, Middle East, and African plants with identified kits. Export packing depends on the item and the destination.
