Coolant Filtration Yields Significant Savings
While many shop managers intuitively understand the importance of properly maintaining coolant, it's likely that few have calculated the actual cost savings of doing so. Keller Products says the 80-percent savings realized by one customer after installing pump/skimmer units is typical.

High-Capacity Bag Filters
To prevent deterioration in cutting fluid chiller performance, Keller Products features a line of bag filters that removes virtually all particles as fine as 1 µm from the fluid before it enters the chiller. The bag filters, rated for flows ranging from 30 to 160 gpm, have ¾" or 1 ½" NPT inlet and outlet fittings. The filter bags, available with retention efficiencies from 1 to 100 µm, have high solids holding capacity and are easily changed in a few minutes without tools, the company says.

Separator Solves Tramp Oil Dilemma
Debco Machine, Inc.

About 1 gallon per day of tramp oil enters the 100-gallon coolant sump of this machine.

A Separator Solves The Tramp Oil Problem
With their strong attention to routine housekeeping, it's not surprising that this shop carefully researched all methods for removing tramp oil from coolant in machine sumps. If tramp oil is allowed to build up in the coolant, the resulting shop odor, smoke generation and unpleasant conditions for the operators will quickly undermine all efforts to keep a clean shop and maintain an optimum working environment.
