Cold Storage

A cold storage facility had scale problems in an evaporative condenser using traditional chemical treatment. The facility planned to expand and wanted to avoid scale issues with their new condenser, while cleaning up the scale in their existing equipment.

A CHC 40-GPM unit and auto-backwashing filter was installed. CHC also passivated the new condenser as part of commissioning.

Scale was removed from the old condenser after just four months. The tubes in the new condenser continue to look new. Bacteria counts in both systems were well below control limits of 10,000 CFU/ml.

Cycles of concentration increased from 2.0 to 4.0 after CHC installation. The customer is now saving 8.7 million gallons of make-up water annually at this facility, and has installed four additonal CHC treatment systems in three other facilities.
