The industrial manufacturing industry has long embraced powder coating as the preferred method of applying paint to finished metal surfaces. A reduction in production costs, better coatings with improved corrosion protection, and the reduction of VOC emissions are some of the advantages

First developed in the late 1960’s, powder coatings work by applying a positively charged, dry, free-flowing powder to a grounded metal substrate. Curing in an oven allows the powder to flow together and form into a durable film after cooling.

When production requires small batches and non-continuous runs, the least efficient component of the process is the heating of both the curing ovens and pre-treatment solution tank. Rinsing the metal to be power coated with a pre-treatment solution is important because it ensures a uniform application. 

This method was designed to increase energy efficiency of production.This solution takes advantage of available oven space by adding a heat exchanger to capture latent heat that would otherwise be wasted. The system is comprised of a closed, coupled pumping system that is fully valved and controlled complete with non-return valves.
