Process Cooling

A specialty aluminum molding plant had to shut down its process every six months to remove scale from a plate and frame heat exchanger. An estimated $100,000 was lost for every 16 hours of downtime.

In 2005 the plant installed a CHC-40 GPM system with filtration on the cooling towers that supported the heat exchanger.

Installation engineers monitored temperatures across the heat exchanger fearing any additional scaling would cause a major issue because inside temperature of the mold was 2,700°F and space was tight. After more than two years of CHC treatment facility personnel reported temperatures across the heat exchanger remained within normal operating parameters.

Cycles of concentration increased from 2.0 to 3.8, saving 3.5 million gallons of water annually. Costly downtime previously required to clean scale was eliminated.
