LOCATION: FORTUNE 500 SMALL ENGINE MANUFACTURER

GOALS: Reduction in the Volume of Aqueous Coolant Usage Recovery and Re-use of Tramp Oil

SCENARIO: Due to significant coolant and hydraulic oil costs incurred in volume production operations of this FORTUNE 500 firm, corporate directives to plant management and chemicals' suppliers targeted reduced coolant usage as part of overall cost reduction programs.

PROBLEM: Factory management had to overcome significant tramp oil contamination of the company's 30,000 gallon coolant reservoir and the rapid coolant degradation associated with such heavy usage.

SOLUTION: Utilizing a Suparator® to continuously separate tramp oil and coolant returning to the central coolant reservoir, Mobil Oil and Castrol participated in a 90-day trial that closely monitored tramp oil loading and resultant degradation, during which tramp splitting coolant formulations were used with great success.

No coalescing media or filters were required to complete the separation, and the system was able to handle 'spike' and large tramp releases due to line blow-outs.

APPLICATION: TRAMP OIL RECOVERY in METAL WORKING FLUIDS

FINDINGS: Post-installation Suparator® operational findings show:

• with the system settling to a constant, steady state, essentially free from biodegradation, coolant life dramatically improved - from a prior 21 days' cycle - to still being in use at the end of the 90 days' trial period;
• with +/- 2.5% tramp oil content, coolant is repeatedly recycled to the CNC milling and boring operations for re-use;
• the coolant reservoir's much extended 'bath life' yielded considerable savings in consumable costs and liquid disposal costs;
• the operators' handling and work area conditions
