Product
Shell and Tube Heat Exchangers
Shell and tube exchangers have been the heart of our work since 1989. Every unit is sized in HTRI, checked mechanically in PV Elite and built under our ASME U or U2 stamp, from compact booster coolers to large exchangers with expansion bellows for refineries and gas plants.
Why customers choose it
Designed in HTRI
Thermal design by a 25-member process team with 12 years of HTRI experience.
ASME U and U2 stamped
Built and stamped under our own ASME authorisations, with NB registration when you need it.
High pressure
We have hydro-tested exchangers at up to 425 bar.
Big and thick
Shells rolled up to 6 m in diameter and tubesheets up to 400 mm thick.

Types and configurations
Fixed tubesheet with expansion bellow
Handles large temperature differences between shell and tubes.
U-tube
Free thermal expansion, good for high tube-side pressure.
Floating head and stacked units
Removable bundles and stacked exchangers such as our 35-tonne unit for IOCL Panipat.

Questions buyers ask us
Can you build shell and tube exchangers with expansion bellows?
Yes. Fixed tubesheet exchangers with expansion bellows are one of our major products; we recently built a stainless steel unit with an expansion bellow and internal coil for KLJ Petroplast.
Do you ship to the UAE, Saudi Arabia and the rest of the GCC?
Yes. Both our factories are in Coimbatore, about 195 km from Cochin port, with Tuticorin and Chennai also within reach. We pack for sea transport and ship to ports such as Jebel Ali, Khalifa Port, Dammam, Jubail, Sohar, Hamad and Shuwaikh. Our equipment is already in service with ADNOC, PDO Oman, OQ, QAPCO, Kuwait Oil Company and Ma'aden.
Can our inspector or a third-party agency witness the tests?
Of course. We regularly work with Bureau Veritas, Lloyd's Register, TÜV NORD, SGS, HSB and other agencies, and your own inspector is welcome at any stage.
