The Patriot IFR System is integrated with either 250-gallon/250-gallon or 500-gallon/500-gallon process tanks that are equipped with a proprietary mixing system to provide a homogeneous feed to the high-speed disc centrifuge. The Patriot system is also furnished with a hydrocyclone pre-clarifier to remove gross solids and minimize loading on the centrifuge.  The pre-clarified coolant is then directed to an economizer to preheat the water-soluble coolant prior to entering an immersion electric heat chamber or pasteurizer where the coolant is heated to 165° F to sterilize the coolant and kill any bacteria and/or fungal growth. The heated coolant is then directed to the centrifuge where an efficient three-phase separation occurs at 9,000-g’s of centrifugal force occurs to remove tramp oil down to 0.0025% and metal fines, swarf and particulate matter, etc. to ≤1-micron range.

The purified coolant is then directed to the economizer to aftercool the coolant and provide thermal exchange to the incoming coolant to reduce the BTUs consumed by 50% during the pre-heating process.

The Mitsubishi self-discharging centrifuge will undergo a period self-cleaning mode where the captured solids ae ejected and the centrifuge disc stack is subjected to a clean water flush prior to being placed back on-line.  The entire centrifuge processing and self-discharging process is fully automated to minimize operator attention in as much as possible. The separated tramp oil is directed to a 55-gallon drum for further processing or reclamation by a used oil recycling service.

New coolant is then made up within the clean tank with a coolant proportioning device to top off the recycled coolant reclaimed by the Patriot high speed disc centrifuge system.
