Autonomous tramp oil removal to below 0.5%
T.O.S.S. operates autonomously at a machine sump, parts washer, large reservoir, or coolant pit. It removes free and dispersed tramp oil and returns clarified coolant by gravity without interrupting the machine.
More than surface oil removal
A floating skimmer draws the oil-rich surface layer through a bag filter and into a polypropylene coalescing pack. The media separates free and mechanically dispersed tramp oil before clarified coolant returns to the reservoir by gravity. Tank, media, skimmer, pump, and discharge are integrated on one skid.
Skim, filter, coalesce, return
The skimmer removes the oily surface layer, the bag filter captures solids, and the coalescing media separates tramp oil before clarified coolant returns by gravity.
Skim the surface
A floating skimmer rides the level and pulls the oily top layer off the surface.
Filter the solids
The supply pump sends it through a bag filter (100µ supplied, 1 to 200µ available) to drop suspended solids.
Coalesce the oil
Droplets attract to the polypropylene plates, combine, and rise into an oil layer that overflows to the trough and gravity-drains to your drum.
Return clarified coolant by gravity
An adjustable weir maintains the oil layer while clarified coolant returns to the reservoir by gravity. Separated oil drains independently without an oil pump.
Compatibility requirement: chemically emulsified oil cannot be removed through coalescing, and emulsifying cleaners should not be used with the unit. When separation behavior is unclear, run the 30 to 60 minute bottle test or request a fluid-compatibility review.
Tramp-oil control for one or multiple reservoirs
Use a standard T.O.S.S. model for dedicated treatment at one sump, reservoir, pit, or parts washer. Use the portable T1 when multiple independent reservoirs can share one separator on a planned schedule. Continuous oil loading, reservoir volume, fluid chemistry, and required treatment rate determine the configuration.
MT2 through 50
Floor-standing units sized by loop rate. Carbon-steel divided tank, air or electric pump, V-bottom and bag-filter solids options, optional pre-filter, casters, and extra leg length. Standard and custom sizes.
T.O.S.S. T1
To treat one reservoir at a time and move between locations, the T.O.S.S. T1 provides the same coalescing separation in a portable, skid-mounted configuration available in six builds.

Options include a pre-filter assembly, V-bottom, casters, extra leg length, electric pump, vertical or ballast skimmer, and an ozone generator. Ozone replaces routine biocide dosing with automated bacteria control and odor neutralization. Routine ownership care centers on condition-based filter service and planned cleaning of the accessible separator components. Request the full data sheet →
Select the skimmer for the reservoir
The sump shape determines which skimmer fits.
Vertical floating skimmer
A stationary float that clamps to the side of the reservoir, skims the surface, and rides the level up and down. Built for shallow, hard-to-reach sumps; the reservoir must not drop below the float's lowest point.
Ballast floating skimmer
For deep open sumps with large level swings or turbulence, such as central filtration systems and coolant pits. Water-ballasted on site so the suction pipes sit right at the surface.
Separation performance and operating results
volume hauled
by volume
Holding tramp oil below half of one percent helps extend coolant service life. Recovered oil with 1% to 2% water content may be suitable for reclamation or reuse, subject to composition, waste classification, and recipient requirements.

Product and ownership questions
- 01
How does T.O.S.S. differ from surface skimming or top-suction filtration?
Top suction describes where fluid is collected, not how the oil is separated. Equipment that only collects or filters the oil-rich surface layer may leave mechanically dispersed droplets in the fluid. T.O.S.S. draws from the surface, filters suspended solids, and passes the fluid through coalescing media that separates free and mechanically dispersed tramp oil before clarified fluid returns to the reservoir. The media separates 99% of 20-micron oil droplets on the first pass.
- 02
Will it work with our fluid?
T.O.S.S. is compatible with water-based coolants, synthetics, and alkaline wash water carrying free, dispersed, or loosely emulsified oil. Chemically emulsified oil cannot be removed through coalescing. When separation behavior is unclear, request a fluid-compatibility review.

What routine maintenance is required?
T.O.S.S. operates autonomously without interrupting the machine. Routine ownership care is limited to condition-based bag-filter service and planned cleaning of accessible separator components. EdjeTech supplies replacement media, parts, and technical support by model.
- 04
Can fluid compatibility be confirmed before selection?
Yes. An EdjeTech engineer reviews the fluid chemistry, separation behavior, contamination, and operating conditions.
Request an application review → - 05
What support is available after purchase?
EdjeTech supplies replacement skimmers, coalescing media, bag filters, drawings, operating guidance, and troubleshooting support for installed systems.
Review support resources → - 06
Can we feed it with a pump we already own?
Only a progressive-cavity or air-diaphragm pump. Never a centrifugal pump: a centrifugal impeller shears tramp oil into fine droplets and disperses it back through the coolant, undoing the separation.
Skimmer floats, coalescer packs, bag filters
Replacement skimmers, coalescing media, and bag filters are available by model, together with manuals and technical support for installed systems.
