Now, John Thompson is the Power Division of ACTOM (Pty) Ltd, with its principa focus on being the best boier and environmenta soutions company. We speciaise in the design and manufacture of package firetube boiers and industria watertube boiers and aso retrofit and maintain utiity boiers and environmenta equipment. This brochure covers the products and services of our Package Boiers business unit. The firetube boiers range in steam capacity from 1 t/h up to 32 t/h and incude coa-fired boiers, biomass-fired boiers, oi / gas-fired boiers and customdesigned waste-heat boiers. John Thompson s head office and factory are ocated near Cape Town and during the past 60 years we have suppied over firetube boiers to customers in many industries in Africa, Europe, South-East Asia, the Midde- East, South America and Austraia. A of our boiers now incorporate spira-tube technoogy, deveoped in our test centre, which enhances therma efficiency and reduces fue consumption and CO 2 emission. The boiers are currenty designed and manufactured in compiance with the atest internationa standard, EN12953, and are inspected and certified by an Approved Inspection Authority before dispatch.
