India's Leading Heat Exchanger Manufacturer
For over 35 years, United Heat Exchangers has been designing, manufacturing and exporting world-class heat exchange equipment from Coimbatore, Tamil Nadu — the engineering capital of South India.
Dedicated to Heat Transfer Excellence Since 1989
United Heat Exchangers was founded with a single purpose: to provide the Indian process industry — and the world — with a reliable, all-under-one-roof source for every type of heat exchanger equipment. Since our establishment in 1989, we have grown into one of India's foremost manufacturers and exporters of heat exchangers, serving diverse industries from power and refining to pharmaceuticals and food processing.
Our facility in Coimbatore, Tamil Nadu is equipped with advanced manufacturing infrastructure and staffed by a team of highly experienced engineers and technicians. Every heat exchanger we produce — from a compact brazed plate unit to a large air-fin cooler — is built to exacting standards and backed by rigorous quality control at every stage of production, from raw material sourcing to final dispatch.
We don't simply manufacture and supply. We partner with our customers to understand their thermal engineering challenges, select the right solution, and provide ongoing service, maintenance, and upgrade support throughout the lifecycle of the equipment. Our round-the-clock customer service team is always available to address technical queries.
