Who We Are — Leading Heat Exchanger Exporters in India
As one of the most trusted heat exchanger exporters in India, United Heat Exchangers competes on technical quality — not just price. For more than 35 years, buyers from the United States, Saudi Arabia, the United Arab Emirates, Germany, and every major industrial economy in our export markets have chosen us for one consistent reason: we deliver equipment that performs to specification, ships on schedule, and arrives with a complete documentation package. This includes mill test reports, radiography records, hydrostatic test certificates, Authorised Inspector sign-off, and nameplate data.
If you are evaluating a heat exchanger exporter for your next project, our engineering team responds with a detailed technical proposal — not just a price quotation. That holds whether you are comparing American-built units against an Indian heat exchanger exporter, sourcing German- or UK-compliant alternatives in Europe, or coordinating procurement through Middle East hubs such as Dubai.
We manufacture across three core product lines, each engineered, thermally rated, and documented to the same code-compliant standard:
Shell and Tube Heat Exchangers
Our original and highest-volume product line since 1989. Fixed tube sheet, U-tube, floating head, and kettle reboiler designs, built to TEMA-R/B/C and ASME U-Stamp standards.
Plate Heat Exchangers
Gasketed and brazed plate designs for compact installations and high-efficiency heat transfer duties where footprint and thermal response time matter most.
Air-Cooled Heat Exchangers
Fin-fan and air-cooled condenser systems for sites with limited process water, sized for refinery, gas processing, and power plant service.
What We Manufacture
We manufacture across three core heat exchanger product lines so the design your process actually calls for is the one you get, not whichever type happens to be in our catalogue. Every unit is engineered to the applicable design code and buyer specification, whether that's TEMA, API 661, or PED.
Shell and Tube Heat Exchangers
Our original and highest-volume product line since 1989, built to TEMA-R, TEMA-B, or TEMA-C depending on the service classification. As premier shell and tube heat exchanger exporters in India, we ensure top-tier fabrication. If you need a reliable shell and tube heat exchanger supplier in India for domestic or international projects, we cover:
- General process service, clean fluids, small temperature differentials (TEMA-R, B, C)
- High-pressure, high-temperature services; steam heaters; kettle applications (TEMA-R, B)
- Dirty service, high fouling, easy bundle pull for cleaning (TEMA-R)
- Distillation column reboiling, evaporation, vaporisation duties (TEMA-R)
- Viscous fluids, high fouling, pilot plants, small heat duties (TEMA-R, B)
Plate Heat Exchangers
Corrugated plate designs for duties where footprint and thermal efficiency matter more than raw pressure-handling — typically 3 to 5 times more compact than a shell and tube unit of the same duty. As dedicated plate heat exchanger exporters in India, we supply gasketed, brazed, and semi-welded variants. Recognized as a leading plate heat exchanger supplier in India, our units are used for:
- General liquid-liquid duties, HVAC, food and beverage processing
- Compact, high-pressure duty with no gaskets to maintain (refrigeration, district heating)
- Aggressive fluids and refrigerants that would attack a gasket
- Viscous, fibrous, or particulate-laden fluids
Air-Cooled Heat Exchangers
Fin-fan systems built to API 661, for sites where process water is scarce, expensive, or environmentally restricted. We are highly rated air cooled heat exchanger exporters in India, providing custom fin-fan solutions. As a trusted air cooled heat exchanger supplier in India, our systems feature:
- Fans mounted below the tube bundle, pushing air upward
- Fans mounted above the bundle, pulling air upward
- Steam turbine exhaust condensing at power plants
- Compressor discharge cooling, gas processing, lube oil cooling in oil and gas facilities

Frequently Asked Questions
What is a shell and tube heat exchanger?
A shell and tube heat exchanger is a pressure vessel in which one fluid flows through a bundle of tubes enclosed inside a cylindrical shell. They are the most widely used heat exchanger type in heavy industry due to their robustness. We are proud to be a top shell and tube heat exchanger supplier in India.
What is a plate heat exchanger?
A plate heat exchanger transfers heat between two fluids across a stack of thin, corrugated metal plates. It does the same duty as a shell and tube unit in a fraction of the footprint. As dedicated plate heat exchanger exporters in India, we supply gasketed, brazed, and semi-welded units.
What is an air-cooled heat exchanger?
An air-cooled heat exchanger (fin-fan cooler) uses ambient air instead of water to cool a process fluid. They are essential at sites where process water is scarce. We operate as a highly requested air cooled heat exchanger supplier in India.
How do I choose between shell and tube, plate, and air-cooled designs?
It comes down to the fluid, the space available, and the site's water access. Share your process data and our engineering team will recommend the product line that fits.
Which countries import the most heat exchangers from India?
The largest importers of heat exchangers from Indian exporters are Saudi Arabia, the UAE, Qatar, Kuwait, and Bahrain. Significant volumes also go to the USA, Germany, the UK, Singapore, South Korea, and Australia.
What certifications are required for heat exchangers?
For the USA and Canada, the ASME U-Stamp is legally required. For Europe, PED certification is required. Australian projects mandate AS/NZS compliance.
