SKL Maintenance Systems Corporation case study APAC0021 – Chesterton products – Chesterton Industrial Lubricants




Power plants are vital operations that cannot be slowed down by damage. This particular plant’s damage led to a direct effect on the power supply of the electric steel smelters nearby and, at a daily shutdown cost of approximately $330,000USD, it’s detrimental to the finances of the plant. Thanks to Chesterton’s combination of Chesterton® 346 Descaler and Chemical Cleaner, Chesterton® 803 Industrial and Marine Solvent II, and Chesterton® 775 Moisture Shield, the client was able to get back to work quickly and easily!

Steel plant transformer station was having difficulty cleaning high voltage insulators and transformers. Cement-like scale (thickness 1 – 2.5 mm) on the high voltage insulators caused interruptions or shut-downs.

This had a direct effect on the power supply of the electric steel smelters and other production segments. The cost for a daily shutdown is approximately 330,000 US/day.
