How Thermax solves industry
challenges

01 High efficiency steam engineering solutions

Thermax delivers high-performance thermal systems engineered for efficiency, reliability, and safety. Our solutions are designed to meet the rigorous demands of medium to high temperature industrial operations across sectors.

02 Modular & skid mounted systems

Our modular boilers and heaters are preassembled and factory-tested, allowing for rapid on-site installation with minimal civil work. This streamlined process reduces commissioning time, site preparation costs, labour costs, and project risks, proving optimal for tight project schedules or remote locations.

03 Customised designs for industry specific needs

We customise the system configurations based on industry-specific process parameters, space availability, and fuel type, ensuring maximum reliability and compatibility with plant operations, even under demanding process conditions or spatial constraints. Our ultra-low emission combustion technologies help clients comply with industry-specific environmental norms and enhance their green credentials.

04 Hybrid systems with multi-fuel handling capability

Our systems are engineered to seamlessly process a wide range of 140+ fuels, including biomass, waste-derived, and conventional fuels, ensuring uninterrupted operations, cost optimisation, and enabling clients to switch fuels without compromising thermal output or compliance in dynamic energy markets.

Our products

Solid Fuels, Agro Waste, Biomass Fired Boilers

TBWES offers a comprehensive range of solid fuel-fired boilers featuring IR-CFBC boilers, AFBC boilers and grate boilers (travelling grate, reciprocating grate, pinhole grate and dumping grate), which are engineered to meet diverse industrial steam and power generation needs, harnessing a wide range of solid biomass, agricultural waste, and conventional fuels.

Waste to Energy (WTE) Boilers

TBWES provides advanced green solutions for converting waste to energy by combusting non-recyclable solid waste (NRSW), municipal solid waste (MSW), refused derived fuel (RDF), paper sludge, agricultural waste, spent wash and biofuels. Additionally, our heat recovery solutions capture heat from hazardous and non-hazardous waste incineration, downstream of kilns or gasifiers.

Oil & Gas Fired Boilers

TBWES specialises in oil & gas-fired boilers including D-Type boilers and single-drum high-capacity radiant boilers, which can be fully (plug & play) or partially modularised. Our boilers are customised to meet stringent emission norms with fine combustion control and high turndown ratio.

Waste Heat Recovery Boilers (WHRB)

TBWES offers waste heat recovery boilers to utilise waste heat from various processes and applications to improve overall energy balance in refinery, oil & gas and petrochemical complexes, ferrous & non-ferrous metals, cement, chemical, glass and other sectors. Our offerings include a variety of customised, turnkey solutions to generate steam and power.

Lean Gas Fired Boilers

TBWES offers lean gas-fired boilers, which are designed to combust difficult waste and tail gases, including those with low calorific value, slow-burning characteristics, and low combustibles. Our proven designs ensure high reliability for generating process steam or power.

Waste Heat Recovery Units (WHRU)

TBWES' waste heat recovery units (WHRU) significantly contribute to more sustainable and economically viable operations by recovering waste heat and converting it into valuable steam utility for power and process needs.

Heat Recovery Steam Generators (HRSG)

TBWES offers advanced heat recovery steam generators (HRSG) designed to maximise energy efficiency and reduce operational costs.

Fired Heaters

TBWES specialises in fired heaters for the downstream oil & gas, and petrochemical industries. These heaters offer multi-fuel flexibility and are suitable for demanding offshore and onshore environments, ensuring compliance with API (American Petroleum Institute) codes and specific licensor requirements.

Utility Boilers

TBWES offers subcritical radiant boilers (up to 3,175 TPH) and supercritical radiant boilers (up to 4,535 TPH), manufactured under license from Babcock & Wilcox, USA.

Our services

Through a dedicated services arm, TBWES specialises in delivering tailored, technology-driven, and experience-based solutions to boiler and heater users. Since the early 1990s, we have successfully supported plant renovation and modernisation (R&M) initiatives, offering customised services that enhance boiler performance, ensure operational safety, and extend equipment life. Our R&M approach is rooted in deep domain expertise, focusing on boiler safety, inspection, and performance optimisation.

Today, our solutions are driving improved process efficiency across a wide range of industries including power utilities, petrochemicals, refineries, fertilisers, steel, cement, sugar, and paper. Our comprehensive service portfolio includes integrity assessments, plant equipment evaluations, and reliability-based maintenance (RBM). To support ongoing safe operations, we also provide boiler health assessments through advanced condition assessment and remaining life analysis, ensuring fitness for service and enabling informed decision-making for long-term asset reliability.
