Integral Systems was founded in 1981 with the purpose of designing, manufacturing and servicing high quality industrial electronic equipment. Over the past two decades they have gained much experience in the engineering and supply of variable speed drive systems, thyristor controllers and industrial automation equipment. This has been supplied to a wide spectrum of industries.

In 1999 they bought a company that had been making ultrasonic cleaning equipment for over 20 years. This is run as a separate division. A full range of cleaners from laboratory desk top models to fully automated 750 litre tanks are now manufactured.

Integral Systems operate from their purpose built factory in Randburg and service and operate throughout South Africa.
