CoolSkim™ Oil Water Separator
Compact Oil Water Separators for Low-Flow Industrial Applications
CoolSkim® compact oil water separators are engineered to separate oil from water in industrial coolant systems, wash water, compressor condensate, and low-flow process streams where traditional skimming alone is not sufficient.
The CoolSkim from Oil Skimmers, Inc. provides controlled separation, managed oil removal, and durable stainless-steel construction — all within a compact footprint.
When properly applied, a CoolSkim operates as a complete, standalone oil removal solution.
1. When Is a Compact Oil Water Separator Required?
In many applications, a tube-type oil skimmer is the simplest and most effective solution — particularly when oil is freely floating and adequate surface area is available.
A compact oil water separator becomes appropriate when:
- Oil is mechanically emulsified and not readily floating
- Internal turbulence prevents natural separation
- Flow velocity limits retention time
- Sump geometry restricts tube travel
- Surface area is limited or obstructed
- Oil must be transferred to a controlled separation chamber
2. How the CoolSkim® Oil Water Separator Works
Controlled Transfer
Oily water enters via pump or gravity feed. Optional 3-Ball Floating Weir intake allows preferential surface draw when appropriate.
Engineered Separation Chamber
Inside the stainless-steel tank, flow is directed through engineered geometry and coalescing media appropriately sized and selected for your application conditions.
The media promotes droplet coalescence, allowing oil droplets to combine and rise under controlled flow conditions.
Managed Oil Removal
Separated oil is removed using Spin Down Weir® (CS 500–2000) or optional tube-type skimmer integration on CS 4000 incorporating Active Oil Removal®.
Active Oil Removal® continuously removes oil from the surface of the separation chamber, helping prevent oil buildup and supporting consistent performance.

7. Engineering Review Recommended
Oil separation performance is influenced by temperature, viscosity, specific gravity, droplet size, and flow dynamics.
For that reason, CoolSkim oil water separators are sized through application review rather than generic performance tables.
Where is the CoolSkim used?
The compact CoolSkim is an ideal oil removal system for a wide range of low flow rate applications:
- Wash tanks
- Small sumps or pits
- Floor scrubbers
- Compressor condensate
A variety of options and customizations are available to fit your application:
- Pumps
- Floating weir oil skimmers
- Hoses and connections

The CoolSkim is comprised of a stainless steel tank (fittings and valves pre-assembled), baffles, adjustable internal weir, and a see-through removable lid. The following options are available:
Floating 3-Ball Weir Intake
Air or Electric Pumps
Coalescing Media Pack
Brings the surface oil from sump into the CoolSkim
Electric/submersible or air-operated double diaphragm pumps are available
The coalescing media pack facilitates oil separation, making oil rise more quickly and easily. The coalescing media pack is removable for easy maintenance and cleaning.
