Configuration Packages:

Base

The PRAB Guardian’s base configuration includes the following components:

• An inlet basket strainer
• Dirty and clean coolant tanks
• A Tramp Oil Separator with a coalescing media pack (tellerettes)
• A floating skimmer assembly
• Steel oil weirs, manifolded together on exterior of the tank
• An automatic air sparging system
• A coolant make-up system
• Control Panel
  • Allen Bradley components
  • HMI
• Voltage: 460/3/60
  • Other voltage options available: contact factory for pricing and lead time

Standard

The PRAB Guardian’s standard configuration features all of the components included in the base version as well as some additional elements. Specifically, this package includes a polishing filter assembly that is typically 20-micron rated and a Coolant Manager. Proven to kill up to 99.9% of coolant bacteria, the Coolant Manager is a safe, economical solution that generates and injects Ozone directly into the coolant. This specific treatment extends coolant life up to 25% and eliminates odors, clogged coolant lines, and slime in sumps. As a result, this decreases the likelihood of employee health issues. Additionally, the coolant manager reduces biocide use and oxidizes bacteria, viruses, cysts, spores, hydrogen sulfate (egg odor), and other contaminants both organic and inorganic.

AC^³

A fully automated coolant concentration controller that is compatible with HG1200 units and above, the AC^³ will maintain set concentration levels within +/- 0.5% accuracy. The exclusive logic built into the controller allows more or less concentrate to enter the discharge flow of the Guardian system. This comprehensive system provides the necessary intelligence to accurately and automatically inject new concentrate only as needed to maintain optimum ratios and achieve maximum tool life.
