Service reliability and ongoing innovation sees Sasol extend our service contract by a further 14 years.

Proxa ensured high quality boiler feed water at Sasol mines

THE CHALLENGE

Sasol urgently required the production of high quality boiler feed water with guaranteed availability.

OUR SOLUTION

Given the project’s time sensitivity, PROXA delivered and installed a series of pre-manufactured, skid mounted units within 6 weeks. PROXA is responsible for the operations, maintenance and ongoing technical support.

HOW PROXA ADDED VALUE

Over the contract period, we continued to optimise the process, reduce operating costs, reduce waste volumes and ensure that the client continually benefited from latest technologies and developments. A recent addition to the plant was the inclusion of an Electro Deionisation unit. Minimising waste generation and protecting the environment. Given PROXA’s reliability coupled with product and service quality, the client elected to defer the expansion existing infrastructure and extended our over-the-fence contract for an additional 14 years.
