Extended life for cooling radiators

Keywords Corrocoat, Coolers, Corrosion

Corrocoat informs us that primary transformer cooling radiators nearing the end of their design life can now be effectively refurbished at an economic cost, using a new process which it has developed.

We understand that extensive surveys carried out on cooling radiators across the UK have identified that a high proportion of those currently in use - while of robust construction with a service life of 30-40 years - are now coming to the end of their design life. These failures are due to relatively small areas suffering corrosion damage; in general, less than 1 per cent of the total surface area.

When initial work using traditional coating solutions proved too costly as a repair method, Corrocoat invested in an extensive R&D programme to establish an affordable, long-term solution to the problem.

As a result, the company reports that it has developed an innovative and effective refurbishment representing a substantial saving over the cost of a replacement unit This system is said to be designed to beat leaks and add substantially to projected service life.

The process developed by the company involves the combination of a range of polymer alloy materials and engineering techniques to reprofile the header boxes of the cooling radiators, effectively sealing the areas at the base of the fins most subject to corrosion damage.
