The smart alternative to old unregulated "baby boilers" — now compliant, safe, and user-friendly thanks to IBR 2007 Chapter XIV regulations.
We started as Govt approved boiler repairers. Today we design, manufacture, and service complete thermal systems.
Thermal Engineers began as Govt approved boiler repairers and erectors in 1980. Our KOALA brand boilers are manufactured under license from the Director of Boilers — full statutory compliance, documented and certified.
We are one of the leading manufacturers of boilers and accessories in Kerala, India. Local presence means faster delivery, on-site installation support, and responsive after-sales service from engineers who know your region.
Beyond boilers — we design thermic fluid heaters, hot air generators, heat exchangers, pressure vessels, distillation units, steel chimneys, and all boiler accessories. We have supplied thermal systems across India and exported to international markets. One team for your entire thermal engineering requirement.
From a 100 kg/hr hotel boiler to custom distillation units for the Agricultural University of Kerala and Plantation Corporation of Kerala — we engineer to your exact process needs, space, and fuel availability.
KOALA thermal systems are operational across a wide range of industries in Kerala and across India.
Hotels need reliable, round-the-clock hot water and laundry steam with minimal operational complexity. Our Hot Water Generators and N-Series boilers are ideal — economical to run, simple to operate, and available in agro waste fuel options which keep costs low. No certified boiler operator is needed for our N-Series units.
Hospitals require steam for CSSD (central sterile supply), laundry, and HVAC — with high uptime expectations. Our IBR-certified boilers deliver dependable steam with full regulatory compliance. We handle the statutory documentation and certifications your facility needs.
Educational institutions, student hostels, and public facilities benefit from our cost-efficient N-Series boilers and Hot Water Generators. Low investment, easy operation, and no need for a certified operator make these ideal for non-industrial settings.
We have designed and supplied steam distillation units for the extraction of essential oils and herbal products — including systems for Kerala Agricultural University and Plantation Corporation of Kerala. We also supply agro-waste fired boilers that utilise rice husk, coconut shell and other farm residues as free fuel.
Food processing requires reliable steam for sterilisation, cooking, cleaning-in-place (CIP), and product heating. Our T-Series boilers provide consistent pressure and temperature for process lines — with multi-fuel options and low maintenance design.
Pharmaceutical manufacturers need clean, consistent steam for autoclaving, sterilisation-in-place (SIP), and process heating. Our IBR-certified boilers are built to maintain steady pressure and steam quality, and we handle all compliance documentation.
Chemical processes often require both high-pressure steam and precision process heat. We supply T-Series steam boilers, Thermic Fluid Heaters (up to 300°C), Hot Air Generators, heat exchangers with static mixing elements, and steel chimneys for fume exhaust — covering the full thermal utility requirement.
Textile dyeing, sizing and finishing are steam-intensive processes running long hours. Our T-Series boilers in three-pass wet back design deliver the steam quality and pressure consistency needed for continuous 24-hour operations with low fuel consumption.
KOALA boilers have been installed across India and exported to international markets — a testament to the quality and reliability of our engineering.
From Kerala to the rest of India — our boilers are operational in hotels, hospitals, pharmaceutical plants, food factories, textile mills, agro-processing units and more. We supply and erect across all Indian states, with our service team available for on-site support.
KOALA boilers have been exported to multiple countries, meeting international quality and safety standards. Our experience with diverse industrial requirements and climates makes us a reliable partner for customers beyond Indian borders.
