Ultraweld Coat is a Heat Exchanger Manufacturer in Malaysia, supplying shell and tube heat exchangers to LNG, refining, petrochemical and oleochemical plants. Units are built at our works in Pune, India and shipped to Peninsular and East Malaysia.
Malaysia’s process industry is concentrated on the coast, at centres such as Bintulu, Kerteh and Pengerang, where seawater is the cooling medium and the air is warm and humid all year. Tubes have to resist chlorides and marine fouling. Palm oil refining and oleochemical plants add duties of their own, heating and cooling viscous oils and fatty acids that foul surfaces. Offshore, exchangers must also be compact and light enough for a platform deck.
Heat exchangers are essential equipment used to transfer heat efficiently between two or more fluids without direct contact. They play a critical role in maintaining process efficiency, reducing energy consumption, and ensuring reliable operation across industries such as oil & gas, petrochemicals, power generation, chemical processing, food & beverage, pharmaceuticals, HVAC, and water treatment. Designed to operate under demanding conditions, heat exchangers improve thermal performance while minimizing maintenance and operating costs.
As a trusted Heat Exchanger Manufacturer in Malaysia, we design, manufacture, and supply high-performance heat exchangers engineered to meet international standards including ASME, TEMA, API, PED, and ISO. Our customized thermal solutions are built using premium materials and advanced manufacturing techniques to deliver exceptional efficiency, durability, and long-term reliability.
Our heat exchangers are widely used in:
We supply heat exchangers across Kuala Lumpur, Selangor, Johor Bahru, Penang, Kuantan, Malacca, Ipoh, Kuching, Bintulu, and other industrial regions in Malaysia. Our products are trusted by EPC contractors, oil & gas companies, petrochemical plants, refineries, power stations, food processing units, pharmaceutical manufacturers, and industrial process facilities.




Engineered surface chambers and gas exhaust components designed for high-temperature industrial applications.
In order to choose a heat exchanger, we must be aware of:
Yes. Refining and oleochemical processes heat and cool oils repeatedly, and recover heat between streams. Stainless steel is commonly used because of the fatty acids involved.
Space and weight are limited and the atmosphere is corrosive, so offshore units are compact and built from materials that resist seawater.
