Process & Thermal Engineering for High-Integrity Heat Exchangers

Safe Professional Innovative
Our Process & Thermal Engineering service provides advanced heat exchanger design, combining deep chemical and mechanical engineering knowledge with industry-leading thermal modelling tools. We don’t simply run software, we interpret the complex correlations behind it to deliver accurate, efficient, and duty-specific solutions. Our team optimises thermal performance, energy recovery, heat transfer efficiency and operational stability across a wide range of industrial processes.

Advanced Thermal Design for Critical Process Applications

Graham Hart Process Technology provides specialist process and thermal engineering services for high-integrity industrial heat exchangers operating in demanding environments. Our engineers deliver accurate, duty-specific thermal designs for applications involving high pressure, high temperature and corrosive process conditions.

We support projects across the nuclear, oil & gas, chemical, pharmaceutical, food and energy sectors, where thermal performance, reliability and compliance are critical to plant safety and long-term operation.

Manufacturing of High-Integrity Heat Exchangers

Engineering Beyond Software-Only Design

Our approach to process and thermal engineering goes far beyond running standard design software. We apply deep chemical, mechanical and thermodynamic expertise to interpret the correlations, assumptions and limitations behind thermal modelling tools.

This ensures:

  • Accurate heat transfer predictions
  • Stable operation across all load cases
  • Optimised energy recovery and efficiency
  • Reduced fouling and pressure drop risks

Our engineers design exchangers that perform reliably in real-world operating conditions — not just on paper.

Optimising Performance for Extreme Operating Conditions

We specialise in thermal design for:

  • High-pressure process streams
  • High-temperature duties
  • Corrosive and aggressive media
  • Critical safety-related applications

Each design is engineered to balance thermal efficiency, mechanical integrity and operational stability, ensuring compliance with global standards while maximising plant performance.

Integrated with Mechanical Design & Manufacturing

Because our process and thermal engineering is delivered in-house, we seamlessly integrate thermal design with mechanical engineering and manufacturing. This eliminates disconnects between design intent and fabricated reality, reducing risk, rework and lifecycle cost.

Clients benefit from:

  • Faster design cycles
  • Improved constructability
  • Reduced project risk
  • Fully accountable engineering ownership
