Application · CNC coolant filtration

Coolant filtration
for CNC machines.

CNC coolant can carry chips, metal fines, tramp oil, and settled sludge. Select filtration and separation equipment by contaminant, or use C.R.O.S.S. for shop-wide coolant recycling.

Equipment selection by contaminant

Match the equipment to the coolant condition

Each technology addresses a specific contaminant or maintenance requirement. Select the condition to review the corresponding equipment and performance range.

01 · Tramp oil
Free oil collects on the sump surface, supports bacterial growth, creates odor, and shortens coolant life.
Recommended equipment
T.O.S.S.
Sump-side coalescing separator for one sump or a few. Skims continuously, holds tramp oil below half of one percent.
<0.5% RESIDUAL · 2–50 GPM

T.O.S.S. T1
The portable single-sump unit that wheels between CNC machines, on shop air.
2 GPM · PORTABLE

When tramp oil occurs with suspended particulate, rising disposal volume, and high coolant consumption, evaluate a shop-wide recycling system.

Shop-wide coolant recovery

Address multiple coolant contaminants

When tramp oil, particulate, coolant consumption, and disposal volume increase together, central recycling can replace separate corrective measures. C.R.O.S.S. pre-filters large particulate, separates free and loosely emulsified tramp oil, and captures fine particulate. The proportioner mixes concentrate and water at the required concentration, while the system maintains clean coolant for immediate use 24/7/365 at 99% or greater uptime.

Compare operating results

Performance differs by product and contaminant. Use your quoted investment and current fluid, disposal, labor, and maintenance costs to estimate simple payback.

Common application questions

  • 01

    Do I need a full recycling system, or a separator or filter?

    A single contaminant in one or several sumps may require only a T.O.S.S., magnetic separator, or paper-bed filter. Where multiple contaminants affect several machines and coolant and disposal costs are increasing, C.R.O.S.S. provides shop-wide coolant recovery.

  • 02

    Will it handle my coolant and metal mix?

    EdjeTech engineers review your fluid before any equipment is proposed. Send your fluid type and brand, your machine count, and the metals you cut.
