How oil and coolant separate —
and when to clean the filters

Rather than relying on chemical agents, GREEN ECO PRO uses structural design to speed up oil-water separation and the settling of contaminants. Below is how our four in-house technologies work and the conditions each one suits.

Four types of contamination, four ways to handle them

01

Oil mist and fumes

Atomised during machining and left hanging in the air around the machine. Extracted at source, trapped by layered filter media, and the separated liquid drains back to the tank.

02

Surface tramp oil

Leaked oil floating on the coolant surface, where anaerobic bacteria breed. A float skimmer follows the liquid level to draw it off, then it is separated physically, leaving the coolant concentration unchanged.

03

Settled metal chips

Iron chips, aluminium sludge and tungsten powder settling on the tank floor and eating into usable capacity. Drawn out continuously under vacuum and caught in a stainless basket that is rinsed and reused.

04

Suspended fines

Very fine powder from grinding and EDM, dispersed through the fluid and too small for a basket to hold. Removed by precision filtration with media rated at 5μm.

Four in-house developments

All four were developed in-house. The S.T.P.M module and the float skimmer are stated as patented designs in the product documentation; the other two are presented as design features. Patent numbers, jurisdictions and scope are available from GREEN ECO PRO for verification.

STPM

Patented

Oil-Water Coalescing Separation Module

Structural design accelerates the settling of suspended solids, while its non-oleophilic material allows fast, continuous oil-water separation. One-piece injection molding and a special star-shaped design increase surface area without altering coolant concentration.

Patented

Float-Ball Skimmer

An anti-twist design keeps the float ball balanced on the water surface and the piping flowing smoothly, automatically adjusting to the water level, with a minimum operating height of just 5 cm.

What We Develop Next

GREEN ECO PRO continues to focus on in-house development. Building on our existing oil-water separation, chip handling and precision filtration, we adapt module designs to different machining conditions so the equipment solves shop-floor problems at a practical price.
