RobKor Engineering Solutions (T/A RKES Pty Ltd) has for the past 16 years been providing heat exchanger maintenance services to the Industry and as a result developed and implemented condenser tube cleaning, maintenance and Inspection (Eddy Current) philosophies, techniques and knowledge that set South African industry power generation standards.


Our experienced maintenance team understands the heat exchanger and Customer production goals. RKES has been a reliable heat exchanger cleaning, maintenance and inspection partner with Heavy Industry throughout South Africa for over two decades.


Specialising in hard-to-clean scale as well as sludge deposits, online maintenance, and outage management and maintenance, RKES utilises the latest available technology that maximises time available for outages.


Our Eddy Current inspection techniques are helping the industry enhance plant availability, its tube heat rate transfer and safer, more efficient maintenance repairs.


In co-operation with our European based companies. We provide the necessary training and support during statutory inspections of vessels as well as such co-operation ensures the company to be ISO 9001 compliant.


As Mechanical Consultants, the company is often requested to assist with outage and refurbishment projects. We specialise in feed heating and condensate plant, but also have resources to assist with the lubrication, H2 cooling water and material handling plants, etc. Our consultants have over 25 years of experience in those fields.


Recently the company undertook International expansion to Eastern European countries such as Poland, intending to introduce our services in that region of the world, where maintenance procedures and practices differ to South African norms.
