Spares, Replacements & Heat Exchanger Upgrades

We provide fast, accurate spare parts, replacement components and full replacement heat exchanger units engineered to integrate seamlessly with existing systems. Our team can reverse-engineer legacy equipment, diagnose failure points and design upgraded units that deliver improved performance, reliability and lifecycle cost savings—often outperforming the original design.

Extending Asset Life & Improving Performance

Graham Hart Process Technology provides spares, replacement components and full replacement heat exchangers engineered to integrate seamlessly with existing systems.

Whether you are simply looking for a replacement gasket or bolting, or have a requirement to replace a complete heat exchanger unit, our engineering team can provide fast, accurate and fully compliant support.

We work across regulated and safety-critical industries, supporting ageing assets, legacy equipment and obsolete designs where reliability, traceability and performance are essential.

Manufacturing of High-Integrity Heat Exchangers

Fast Identification Through Complete Equipment Records

We maintain a complete back catalogue of every heat exchanger and pressure equipment unit we have ever supplied.

The fastest route to support is to quote the equipment serial number, which can be found on the nameplate. This allows us to immediately access original design data, materials, drawings and specifications.

If the serial number is unavailable, our team can:

Interrogate historical project records
Identify equipment supplied to your site, company or end client
Reconstruct designs using archived and engineering data

This capability significantly reduces downtime and eliminates guesswork.

Comprehensive Spare Parts & Replacement Components

We supply a wide range of heat exchanger spare parts and replacement components, all engineered for compatibility, compliance and long-term service.

Typical Spares & Replacements Include:

Gaskets
Bolting and studding
Lubricants
Replacement tube bundles
Heat exchanger re-tubing
Replacement headers and bonnets
Replacement centre sections
Bearings
Motors

All components are supplied to the correct specification for pressure, temperature and service conditions.

Reverse Engineering & Failure Diagnosis

Where original documentation is limited or equipment has been modified over time, our engineers can:

Reverse-engineer existing heat exchangers
Diagnose performance, leakage or failure issues
Identify opportunities to improve reliability and efficiency
Design upgraded replacement components or complete units

In many cases, replacement or upgraded equipment outperforms the original design, delivering improved thermal efficiency, corrosion resistance and lifecycle value.

Designed for Modern Operating Demands

Replacement components and upgraded heat exchangers can be engineered to:

Improve thermal performance
Enhance corrosion resistance
Increase maintenance accessibility
Reduce whole-life operating and maintenance costs

All designs are delivered with the same engineering rigour and quality assurance as new-build equipment.
