John Thompson

What John Thompson does

John Thompson, a division of ACTOM (Pty) Ltd, is a South African industrial energy and environmental solutions company headquartered in Bellville South, Cape Town, with manufacturing facilities in Bellville, Johannesburg and Isando. Tracing its origins to 1824 and operating under the ACTOM group since the mid-twentieth century, the business designs, manufactures, installs and services industrial boiler systems — package boilers (1 to 40 t/h), industrial watertube boilers (up to 200 t/h fossil-fired and 350 t/h biomass-fired at 110 bar / 540°C) and utility boilers (up to 2,800 t/h / 1,800 MW at 260 bar / 580°C) — alongside environmental solutions (air filtration, bag filters, wet scrubbers, cyclones) and HVAC systems. The technical stack centers on proprietary combustion and heat-transfer technologies including spiral-tube technology (proven in 1,000+ installations), the Platen Evaporator retrofit (15-25% capacity uplift), the Surface Type Attemperator, the vibrating-grate Torripac biomass package boiler, and CFD/FEA-led boiler design. Revenue is generated through three mechanisms: (i) one-time project sales of engineered boiler systems and environmental equipment; (ii) multi-year Energy Management contracts that outsource steam/energy operations to John Thompson under fixed-plus-variable commercial structures; and (iii) recurring spares, maintenance, retrofit, training and engineering services, with OEM cast spares produced in-house at the Bellville Foundry. Customers include South African and African industrial enterprises in power generation, sugar/agribusiness (e.g., Sappi, CSKN in DRC), food and beverage (e.g., SA Breweries, Unilever Ghana), mining and minerals, and petrochemical sectors, served through a regional manager direct-sales force supplemented by agents, distributors and the parent ACTOM channel network.

The business is anchored by 85+ years of operating history in South Africa, 4,000+ installed boilers, and a full suite of international certifications (ISO 9001, ISO 14001, ISO 45001, ISO 3834, CE marking under PED 2014/68/EU, Lloyd's Register Approved Service Supplier) along with BBBEE Level 1 status. John Thompson has positioned itself around industrial decarbonization through biomass, biogas, bagasse and waste-to-energy applications, supplemented by a 2018 technology representation agreement with Hamon covering environmental and power-generation systems. Marketing and lead generation operate through industry events (ENLIT Africa, SASTA Congress, Philsutech), trade publications, LinkedIn and YouTube presence, virtual showroom content, and biannual newsletters (Steamtalk, What's Watt).
