STA Central Systems – Fluid Management for Complete Production Lines
Central filtration · Turnkey
When several machines share one coolant, wash emulsion or machining oil, a central system stores, cleans and supplies the fluid from a single point. STA builds these as multi-stage turnkey plants from a flexible modular kit, so tank volume and supply flow are sized exactly to your process.

What a central system can include
- STA centrifugal separators for fine cleaning down to 1–3 µm
- Coarse pre-separation (filters, magnetic drums, etc.)
- Lifting stations for the return flow
- Process supply via ring main
- Partial high-pressure supply up to 100 bar
- Heating and cooling units for temperature control
- Dosing units and agitators
- Tramp oil separation
- Data exchange with your production systems – BUS connection as required
Featured: TTS-60 Twin Tank System
- Central closed-loop cleaning system built around the fully automatic A-25 separator
- Flow rates of 1,000 l/min and more
- Cyclone tank design concentrates particles and prevents sludge deposits
- Inverter-controlled pumps keep supply pressure constant
- Easy to extend: top-up system, cooling, bus interface, remote PLC access and more


Typical applications
Grinding emulsion centres · parts-washing lines · bypass fine cleaning on central coolant systems (grey cast iron and Al-Si machining) · glass processing · closed-loop mass finishing.
