The STS45 system is a disk-type centrifuge with the efficiency to process entire tanks of juice or wine, including the lees, ejecting solids at such a concentration (~ 95% v/v) that no further product recovery is necessary by lees filter or RDV.
The STS45 offers our clients a superior method to manage solids and to eliminate the need for racking of juices and wines, thus avoiding consequent product losses and quality-value downgrades.

A key advantage of the STS45 system over older centrifuges is a very low oxygen pick-up, as low as 0.02mg of oxygen per litre of wine.
Other benefits include…
- Removes solids from white juice instantly
- Reduced fining and settling time
- No cold settling or SO2 needed
- Removal of yeast to arrest fermentation
- Efficiently removes proteins bound to bentonite
- Increased filter life
- Reduce wine loss to lees
The STS45 will efficiently handle a broad range of winery products…
- Whole juice
- White wine ex primary ferment
- Bentonite lees
- Arrested ferments, late harvest and botrytis styles
- Red wine ex primary ferment
- Gross red lees
- Red wine ex malo-lactic ferment
- Wines ex cold stabilisation
- Coarse polishing prior to cross-flow
The STS45 centrifuge is an effective mobile technology for beer clarification too.
