Guardian Configuration Packages:
Base
The PRAB Guardian’s base configuration includes the following components:
Standard
The Guardian’s standard configuration includes all the components of the base version, plus additional elements. Specifically, this package includes a polishing filter assembly rated at 20 microns 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.

Additional features included in the Standard configuration:
Deluxe
The most robust Guardian package, the deluxe configuration includes all the features of the standard version, plus additional components. In lieu of an inlet basket strainer, the deluxe uses a Paper Bed Filter with 10-micron-rated media. A dirty coolant transfer system is also implemented. Base configuration:
Additional features included in the Deluxe configuration:
AC³
A fully automated coolant concentration controller compatible with HG1200 units and above, the AC³ maintains set concentration levels with ±0.5% accuracy. The exclusive logic built into the controller allows more or less concentrated 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, maintaining optimum ratios and achieving maximum tool life.
Easy to Operate & Maintain
The PRAB Guardian Coolant Recycling System is equipped with an automatic air sparger to maintain clean coalescing media, a high-level tramp-oil switch that shuts down the system when the tramp-oil container is full, thereby eliminating the potential for tramp-oil spillage and a comprehensive control panel for ease of operation.
