John Thompson Steam Boiler Maintenance in Johannesburg
John Thompson steam boiler maintenance across Gauteng. Locally manufactured industrial plant with strong local parts support.
John Thompson equipment we work on includes packaged steam and hot water boilers. Commonly replaced parts on this brand are level controls, burners, refractory, and we keep or source these against the unit's model and serial plate rather than by guesswork.
Steam boiler maintenance is a water treatment discipline first and a mechanical one second. TDS control, correct blowdown frequency and condensate return quality determine tube life; the mechanical service simply verifies that the safety chain and burner still perform to specification.
Recovery rate and storage volume have to be considered together; adding heating capacity to undersized storage rarely fixes a peak-hour shortfall. Gauteng municipal water is moderately hard, so scale on elements and heat exchangers is the single most common cause of falling performance.
