We manufacture and supply a comprehensive range of heat exchangers engineered for reliable, high-performance heat transfer across industrial applications. Our units are built to operate under demanding conditions, offering robust thermal efficiency, mechanical durability, and long service life. Designed to handle a wide variety of fluids, pressures, and temperatures, our heat exchangers are suitable for petrochemical plants, refineries, power generation facilities, offshore installations, and other heavy-industry environments. Custom materials, configurations, and design options are available to meet specific process requirements and ensure optimal energy transfer, ease of maintenance, and overall operational efficiency.
The backbone of heavy industry heat transfer. Available in fixed tube sheet, U-tube, and removable bundle configurations for high-pressure and high-temperature service.
Compact, high-efficiency heat transfer ideal for close temperature approach applications. Available in gasketed, welded and brazed plate models.
Heat rejection without water consumption. Optimized for thermal performance, mechanical robustness and reduced noise and vibration.
Cost-effective solution for applications with minimal thermal expansion differences. Ideal for clean services where tube bundle removal is not required.
Flexible design accommodating thermal expansion without expansion joints. Suitable for high-temperature differentials with easy bundle removal.
High-quality tube bundles manufactured to precise specifications. Available in stainless steel, copper alloys and titanium for corrosion resistance.
Easy maintenance access with removable tube bundles. Ideal for applications requiring regular inspection, cleaning or tube replacement.
Our products and services are widely used across multiple industries including:
Heat exchangers for refineries, petrochemical plants, and processing facilities
Thermal, combined cycle and renewable integration power generation facilities
Marine vessels and offshore platform installations worldwide
Steel manufacturing and heavy industrial processing applications
Upstream and downstream oil & gas facilities and installations
Chemical processing and industrial manufacturing operations
High-quality heat transfer solutions for the global energy industry
Our engineering team combines practical experience with modern design tools to deliver optimized solutions. Expertise highlights include:
Thermal and mechanical design using industry-standard software for optimal heat transfer performance and structural integrity.
Expert materials selection for corrosion and erosion resistance, ensuring longevity in demanding operating environments.
Finite element analysis (FEA) for mechanical integrity and stress analysis to validate designs before fabrication.
Compliance design to international codes and standards including ASME, TEMA, API, and TIA-942-B where applicable.
Custom fabrication capabilities for unique process requirements, delivering tailored solutions for specific applications.
Comprehensive QA/QC processes including NDT, hydrostatic testing, and third-party certification to ensure reliable performance.
Quality is a cornerstone of our business. We follow rigorous quality assurance and quality control (QA/QC) processes throughout the project lifecycle:
Material traceability and certified test reports (MTRs) for complete documentation
NDT including radiography (RT), ultrasonic testing (UT), magnetic particle (MPI) and dye penetrant (DPI)
Hydrostatic and pneumatic pressure testing for safety and performance verification
Final inspection and third-party certification when required by project specifications
Although some industry-specific certifications (where applicable) are pursued through accredited external bodies, our internal systems and processes are organized to meet international standards and client-specific QA requirements.
We are committed to promoting sustainable practices and innovation in the steel and energy industries. Our sustainability priorities include:
Designing for energy efficiency and reduced operational losses to minimize energy consumption
Selecting materials and coatings that increase service life and reduce waste
Supporting clients to adopt cooling solutions that conserve water and lower carbon footprint
Continuous R&D to improve heat transfer performance and reduce environmental impact
