Automatically Monitor and Control Coolant Concentration

PRAB, Inc. has introduced an exclusive new feature for monitoring and controlling coolant concentration in its Guardian Coolant Recycling System. The AC³ (Automatic Coolant Concentration Control) is designed to continually monitor coolant concentration levels and adjust automatically to maintain programmed ratios within +/- 0.5% accuracy. The system achieves this critical balance by taking continuous concentration measurements using an automatic refractometer. The readings are analyzed by a series of algorithms built into the exclusive software package. The intelligence automatically determines action, opening and closing valves and turning on and off a pump delivery system.

The AC³ works exclusively in conjunction with the PRAB Guardian Central Coolant Recycling System. "The Guardian uses a comprehensive coalescing filtration process, effectively removing mechanically dispersed tramp oils to 0.1% or less," said a company spokesperson. "The Guardian Coolant Recycling System has demonstrated a reduction in haul-away costs by 90%, and has lowered new coolant purchase up to 75%. Payback on equipment purchase is typically six to nine months."
