CouplerTec Electronic Rustproofing

To Whom is may concern.

Mac's Engineering is one of Australia's largest body building companies that supplies purpose built trays, bodies and accessories for the coal mining industry.

Mac's company policy to use only the best available products and materials and is why CouplerTec Electronic Rustproofing Systems are still the preferred Rustproofing method for coal mining vehicles.

To date there are over 700 of these mining vehicles that have had protection from the highly corrosive sulphur with Electronic Rustproofing Systems supplied by CouplerTec.

The new latest Computerised Electronic Rustproofing Systems from CouplerTec are proving to be even more effective against corrosion than previous models and the added features these systems now have is certainly an added bonus.

Yours faithfully,
