Product
Economizers
An economizer picks up heat that would otherwise go up the stack and uses it to warm boiler feedwater, which cuts fuel use. We build finned tube economizers using the same in-house finning machines as our air coolers, with IBR registration for steam-side service.
Why customers choose it
In-house finning
Extruded and embedded fins on tubes up to 16 m.
Lower fuel bills
Recovered heat means less fuel for the same steam.
IBR registered
Designed and inspected under the Indian Boiler Regulations where needed.
Built to last
Materials chosen for flue gas temperature and dew point.

Questions buyers ask us
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.
