For over five decades, Marshall Fowler has been a trusted name in thermal engineering in South Africa and beyond. Since 1974, we have specialised in the design, manufacture, installation, and servicing of electrode steam and hot water boilers, as well as gas-, diesel-, and paraffin-fuelled Windsor boilers. We deliver tailored boiler and steam installations across a diverse range of industries—mining, hospitals, food processing, textiles, abattoirs, and humidity control systems—with unmatched precision and performance.
Our services include the local manufacture of our proprietary ES, EW, and Mini electrode steam generators and hot water boilers—designed specifically for South African conditions. We also supply gas, diesel, paraffin, and heavy furnace oil (HFO) Windsor boilers, alongside calorifiers, feedwater tanks, heat exchangers, inline heaters, and superheaters—all custom-engineered for optimal integration.
Complete boiler and steam installations from Marshall Fowler cover everything—from boiler selection and pressure vessels to pipelines, steam-jacketed pots and kettles, electrical control panels, lagging, cladding, and water treatment systems. We ensure that every installation aligns with industry best practices for safety, efficiency, and longevity.
Maintaining system integrity is critical. That’s why our scope includes 12-monthly and 36-monthly statutory inspections, as well as comprehensive site services, repairs, and plant tuning. With Marshall Fowler, all components of a boiler-steam system—installation, inspection, maintenance—are handled seamlessly under one roof.
