STA Coalescers (DPS) – Static Tramp Oil Separation
Tramp oil separation · Stainless steel
STA DPS plate separators remove large amounts of free tramp oil from coolant emulsions, washing and degreasing baths, and wastewater. They work only with gravity and coalescence: as the liquid flows through the plate pack, small oil droplets merge into larger ones, rise to the surface and run off continuously.
This works whenever the two liquids differ in density by at least 5% – for example hydraulic oil in a coolant emulsion.
Key features
- Static unit with no moving parts – completely wear-free
- No consumables and very low operating cost
- All stainless steel, suitable for hot and aggressive fluids (pH 3.5–14, up to 90 °C)
- Automatic level monitoring for unattended operation
- Complies with the German Water Resources Act (WHG §19)
- Options: thermal insulation or heater, mobile base frame
- Pairs with STA centrifugal separators for complete bath care – the separator removes solids, the coalescer removes tramp oil
