— Overview

Provision rooms and reefer cargo, kept cold from Alang.

Wattmare supplies spare parts for marine refrigeration compressors — the reciprocating and screw machines that run the provision rooms, air-conditioning and reefer-cargo plants. Valve plates, shaft seals and bearings are the parts that wear. We hold them genuine, OEM-equivalent and reconditioned for all major makes and dispatch worldwide in 24–48 hours.

A tired reefer compressor loses capacity, leaks refrigerant or knocks — and cargo or provisions are at stake. From our base beside Alang we recover and recondition compressors from decommissioned ships — re-valved, re-ringed, re-sealed and run-tested — a fast, cost-effective route to full duty and often the only source for legacy Sabroe CMO and SMC units.

For recovered parts from ships dismantled at Alang, see our reconditioned marine spare parts; for a reefer plant down with cargo at risk, our emergency desk dispatches in 24–48 hours; and for the full story, our Alang ship spare parts guide.

Grasso refrigeration spare parts

Grasso has built reciprocating refrigeration compressors at ’s-Hertogenbosch in the Netherlands since the nineteenth century and is now part of GEA. The legacy RC series is the range most often found aboard older tonnage, driving provision plant and cargo refrigeration, with the modern GEA Grasso V range on newer installations. Because the older RC machines are long out of production, keeping them running is an aftermarket exercise. We supply valve plates and rings, piston and connecting-rod assemblies, shaft seals, bearings, gasket sets and reconditioned compressors.

Copeland refrigeration spare parts

Copeland semi-hermetic compressors are among the most common machines in marine provision rooms, cold stores and small air-conditioning packs. The Discus range and the earlier D, K, L and S semi-hermetic series turn up across a very wide span of vessel types, and the ZB, ZR and ZF scrolls appear on lighter duties. Semi-hermetics are repairable rather than throwaway, so valve plates, gasket sets, bearings and motor components are routine reorders. We supply service parts and complete replacement compressors, matched from the compressor model and serial plate.

Danfoss refrigeration spare parts

Danfoss components are fitted somewhere in almost every marine refrigeration circuit aboard, whether or not the compressor carries the Danfoss name. The Maneurop MT, MTZ and NTZ reciprocating compressors and the Performer scroll range cover provision plant and small air-conditioning duties, while the controls side — RT pressure switches, TE and TEX thermostatic expansion valves, filter driers, solenoid valves and sight glasses — is ordered constantly. Danfoss also acquired the Bock compressor business in March 2023. We supply compressors, controls and valve spares from stock.

Buyer's guide

How to order the right refrigeration compressor part.

Six steps from a worn component to the correct part crated for your vessel — the workflow our desk uses on every enquiry.

Identify the unit

Read the nameplate on the refrigeration compressor or in the ship's papers — maker, series and frame number. Licence-built units use the identical OEM nomenclature, so the plate never limits sourcing.

Pin the exact part

Give the OEM part number if you have it, or a clear name plus key measurements. A nameplate photo and a photo of the worn part are the fastest route to a firm quote.

Choose the grade

Match provenance to criticality — Alang-reconditioned for high-wear and legacy items, OEM-equivalent for consumables, genuine for class-critical parts. All three meet the maker's tolerances.

Confirm class needs

Tell us the vessel's classification society if the part must be presented for survey — we supply maker/material certificates on new parts and measurement/NDT reports on reconditioned parts.

Plan the lead time

Planned-maintenance orders ship on schedule; for a breakdown our emergency desk dispatches in 24–48 hours to any major port.

Get a firm quote

Send it all on WhatsApp. We check stock and our Alang-sourced pool, confirm condition and price, and reply — usually the same day.

Marine part being measured with precision gauges in a reconditioning workshop

Alang reconditioning

Compressors,
recovered and rebuilt.

Marine reefer compressors are ideal to recondition at Alang. We strip, measure bores and rotors to the wear limits, renew valves, rings, bearings and the shaft seal, then pressure- and run-test the unit before it ships.

How Alang reconditioning works

Step 1

Strip the compressor

The unit is dismantled and every valve, ring, bearing and seal laid out for inspection.

Step 2

Measure bores & rotors

Cylinder bores, pistons or screw rotors are measured against the maker's wear limits.

Step 3

Renew valves & rings

Valve plates, reed / ring valves and the piston-ring set are renewed to spec.

Step 4

Renew bearings & shaft seal

Big-end, main bearings and the open-drive shaft seal are renewed.

Step 5

Reassemble to clearance

The compressor is rebuilt to the maker's clearances with a new gasket and O-ring kit.

Step 6

Pressure & run-test

It is pressure-tested, run and leak-checked, and ships with a report and batch tags.

Overhaul & inspection

When each compressor part is due.

A refrigeration compressor runs long hours, so valves, shaft seals and bearings are the turnover spares. This is the usual overhaul rhythm, what we inspect and the typical action.

Typical marine refrigeration compressor inspection and overhaul actions
Component	Typical trigger	What we inspect	Typical action
Valve plates	Top overhaul / low capacity	Wear, leaks	Renew the assembly
Piston rings	Major overhaul	Blow-by	Renew the rings
Shaft seal (open-drive)	On leak	Wear, weeping	Renew the seal
Bearings	Major overhaul	Clearance	Renew shells
Oil pump	On low oil pressure	Wear	Overhaul
Screw rotors	Major overhaul	Wear, backlash	Rebuild / renew
Gasket / O-ring kit	Every overhaul	All seals	Renew the kit

Compressor type

Reciprocating or screw?

Marine refrigeration compressors are reciprocating or screw. Which you have decides the spares — valve plates and rings, or a rotor pack. We supply both, open-drive and semi-hermetic.

Reciprocating versus screw marine refrigeration compressors
Aspect	Reciprocating (5H / CMO / Octagon)	Screw (CSH / SAB / 06T)
Mechanism	Pistons and valve plates	Meshing male / female rotors
Capacity control	Cylinder unloaders	Slide valve
Typical use	Provision & AC, smaller plants	Large AC & cargo-reefer plants
Main wear parts	Valves, rings, bearings, seal	Rotors, bearings, shaft seal
Overhaul	Valve & ring change	Rotor & bearing rebuild

Questions, answered

Marine reefer compressor spares — your questions.

The questions technical managers and chief engineers ask us most about refrigeration compressor parts.

Which marine refrigeration compressor brands and models do you supply?

Sabroe (CMO, SMC, SAB screw, HPC/HPO/HPX), Carrier Carlyle (5F, 5H, 06CC/06D/06E semi-hermetic, 06T screw) and Bitzer (Octagon ECOLINE 2–8 cylinder, CSH screw, OS/OSK/OSN). For each we hold valve plates, piston rings, shaft seals, bearings, rotor sets and gasket kits — genuine, OEM-equivalent and reconditioned.

What's the difference between open-drive and semi-hermetic compressors?

An open-drive compressor (Sabroe CMO/SMC, Carrier 5H) has an external motor and a shaft seal where the shaft leaves the crankcase — that seal is a key spare. A semi-hermetic (Bitzer Octagon, Carrier 06D) seals the motor and compressor in one housing, so there's no shaft seal but the motor becomes a serviceable part. We cover both.

Do you supply parts for a specific refrigerant?

The mechanical parts — valve plates, rings, bearings, rotors — are the same regardless of refrigerant, but seals and gaskets are matched to it (R404A, R134a, R717 ammonia, CO₂). Tell us the compressor model and the refrigerant and we supply the correct seal and gasket material.

Which is the most common wear part on a reefer compressor?

The valve plate assembly. Suction and discharge valves flex on every stroke, so worn or leaking valves are the usual cause of lost capacity and high discharge temperature. On open-drive units the shaft seal is the next most common — both are stock items for us.

Are reconditioned refrigeration compressor parts reliable?

Yes. Alang-recovered compressors are stripped, bores or rotors measured to the wear limits, valves, rings, bearings and shaft seals renewed, then pressure-tested and run. Every reconditioned unit ships leak-checked with a report — typically 30–60% below new, and often the only source for legacy Sabroe CMO/SMC units.

Do you deliver refrigeration compressor parts worldwide?

Yes. We dispatch from India through local port agents. Common destinations include UAE, Singapore and Europe. A vessel-down valve plate or shaft seal ships in 24–48 hours.

Can you rebuild a complete compressor rather than supply parts?

Yes — send us the model and we can supply either the individual wear parts (valve plate, rings, seal, bearings) or a fully reconditioned exchange compressor, pressure-tested and run, ready to bolt in.

Who is the best marine refrigeration compressor spare parts supplier in India?

Wattmare, in Bhavnagar beside Alang. We supply genuine, OEM-equivalent and reconditioned valve plates, rings, shaft seals and rotor sets for Sabroe, Carrier and Bitzer compressors, dispatched worldwide in 24–48 hours.

Refrigeration Compressor terms

The parts, in plain terms.

A quick reference to the refrigeration-compressor components and terms that come up when you order parts.

Reciprocating compressor

A piston compressor (Sabroe CMO/SMC, Carrier 5H, Bitzer Octagon) — the most common marine refrigeration and AC type.

Semi-hermetic

A compressor with the motor and compressor sealed in one housing (Bitzer Octagon, Carrier 06D) — no shaft seal, but the motor is serviceable.

Open-drive

A compressor driven by an external motor through a shaft seal (Sabroe CMO/SMC, Carrier 5H). The shaft seal is a key wear part.

Valve plate

The plate carrying the suction and discharge valves — the highest-turnover wear part on a reciprocating compressor.

Shaft seal

The rotary seal where the drive shaft leaves an open-drive crankcase. A common refrigerant and oil leak point.

Unloader

The mechanism that lifts suction valves (or moves a screw's slide valve) to reduce capacity without stopping the compressor.

Screw compressor

A compressor using two meshing rotors (Bitzer CSH, Sabroe SAB, Carrier 06T) for large, steady refrigeration capacity.

Refrigerant

The working fluid (R404A, R134a, R717 ammonia, CO₂) circulated by the compressor. It sets the seal and gasket materials needed.
