Prevention of Aluminum Corrosion in Closed Loop Cooling Systems

February 27, 2015

Prevention of Aluminum Corrosion in Closed Loop Cooling Systems with OMEGA AQ-6154 eliminates costly down time and molding equipment repairs for a Plastic Injection Molding company.

OMEGA AQ-6154 was applied to a high heat load plastic injection molding operation closed loop system. The previous program observed aluminum corrosion in excess of 10 MPY.

After 95 days of treatment with OMEGA AQ-6154, aluminum corrosion was reduced to 0.20 MPY.
