Control monitors coolant concentration levels in recycling system

Prab Inc. has introduced a new feature for monitoring and controlling coolant concentration in its Guardian™ coolant recycling system.

The AC³ (automatic coolant concentration control) continually monitors coolant concentration levels and adjusts automatically to maintain programmed ratios within +/- 0.5 percent accuracy. The system achieves this balance by taking continuous concentration measurements using an automatic refractometer. The readings are analyzed by a series of algorithms built into the software package to determine action: opening and closing valves, and turning on and off a pump delivery system.

The coolant recycling system uses a coalescing filtration process that mechanically removes dispersed tramp oils to 0.1 percent or less.
