Chiller Compressor Overhaul Kit

What is an Overhaul Kit and What Does It Contain?

Kit contents vary by overhaul scope and compressor type, and usually include:

• Gasket set: gaskets and O-rings to seal the compressor and prevent refrigerant and oil leaks.
• Shaft seal kit: for open and screw compressors, to stop oil leaking from the drive shaft.
• Bearings & bushes: to carry loads and reduce friction.
• Valve plates & reeds: for reciprocating compressors, controlling suction and discharge.
• Piston rings: for compression efficiency and reduced leakage.
• Oil filter & thrust washers: to protect internal components.

Types of Overhaul Kits

• Gasket kit: a basic reseal after opening the compressor.
• Shaft seal kit: to fix oil leakage from the shaft in open/screw compressors.
• Major overhaul kit: includes gaskets, bearings, valve plates, and piston rings for a full rebuild.
• By compressor type: kits for semi-hermetic reciprocating compressors, and others for screw compressors.

We supply genuine overhaul kits compatible with the leading chiller compressors:

• Bitzer: gasket and shaft seal kits for reciprocating and screw compressors (e.g. gasket sets for 4U/4T/6N series and shaft seals for OS screw series).
• Copeland: gasket kits for reciprocating and scroll compressors.
• All Compressors: gasket sets and valve plate kits for the D/V/W series.
• Carrier/Carlyle, Trane, and York: kits compatible by model.

How to Choose the Right Overhaul Kit

Before ordering, prepare: the exact compressor brand and model (kits are model-specific); the compressor type (reciprocating/screw/open); the overhaul scope (gaskets only, shaft seal, or full overhaul) and the refrigerant and oil type. A kit that doesn't match the model won't fit correctly and can damage the compressor. When unsure, request a quote and our technical team will confirm the match before you buy.

When Do You Need a Compressor Overhaul?

The following signs usually indicate the compressor needs an overhaul or rebuild:

• Oil leaking from the shaft or gaskets.
• Unusual noise or vibration from the compressor.
• Weak discharge pressure and declining cooling efficiency.
• High oil consumption or low oil pressure.
• Worn bearings or valve plates found during inspection.

Have a qualified refrigeration technician assess the compressor and define the overhaul scope before ordering the kit.

Why a Genuine Kit Matters

A compressor overhaul is a precise operation, and genuine model-matched kits ensure correct sealing, accurate dimensions, and long life after the repair, while mismatched kits can cause leaks or repeat failures. We supply genuine Bitzer, Copeland, and kits via authorized suppliers, with technical support to define the right kit contents for your compressor model.

For Contractors & Rebuild Workshops

We supply overhaul kits at project and bulk pricing for maintenance workshops, contractors, and compressor rebuild businesses, with fast delivery across the Kingdom, and the option to pair the order with our chiller compressor maintenance and repair services.

Why Choose Cool.sa for Your Compressor Overhaul Kit

Cool.sa supplies genuine, model-matched overhaul kits sourced through authorized channels for Bitzer, Copeland, Carrier, Trane, and York, so you get the correct gaskets, seals, bearings, and valve plates the first time, instead of a mismatched kit that risks leaks or a repeat failure. Our technical team confirms the exact kit against your compressor's brand, model, and overhaul scope before you order, and we support both single-unit repairs and bulk, project-priced orders for contractors and rebuild workshops. With fast delivery across the Kingdom and the option to pair your kit with our chiller maintenance and repair services, Cool.sa is built to get your compressor back to efficient operation with minimum downtime.

Frequently Asked Questions

Q1. What does a compressor overhaul kit contain?

A compressor overhaul kit typically includes a gasket set, O-rings, shaft seal, and bearings. Depending on the compressor type and the scope of the overhaul, it may also include valve plates, piston rings, and an oil filter for a major rebuild.

Q2. What's the difference between a gasket kit, a shaft seal kit, and a major overhaul?

A gasket kit is used to replace sealing gaskets, a shaft seal kit repairs oil leakage around the compressor shaft, while a major overhaul is a complete compressor rebuild that includes bearings, valves, piston rings, and other internal components.

Q3. How do I choose the kit that matches my compressor?

Provide the compressor brand, model, type, and the required overhaul scope. If you're unsure, request a quotation and our technical team will confirm the correct kit, as overhaul kits are model-specific.

Q4. Is an overhaul cheaper than replacing the compressor?

In most cases, yes. Especially for large compressors, a genuine overhaul kit can restore reliable performance at a significantly lower cost than replacing the entire compressor, provided the major internal components remain in good condition.

Q5. Do you support rebuild workshops with bulk quantities?

Yes. We supply compressor overhaul kits at project pricing for HVAC workshops, maintenance companies, and contractors, with fast delivery throughout Saudi Arabia.
