Trident™ Spin Rinse Dryers

Spin Rinse Dryers (SRD) for 75-200mm Substrates

The Trident family of Spin Rinse Dryers (SRDs) provides the state of the art in cleaning, rinsing and drying wafers after wet processing. The systems' non-contact heating results in cleaner N2 because it places a filter after the heater and eliminates direct contact between N2 and heater.

Trident SRDs also use ultra-pure valves and fittings throughout, and all systems include a comprehensive facility panel to precisely control all pressures and flows. These are typical of the design advances and efficiencies that give Trident Spin Rinse Dryer its uniquely attractive performance-to-price value.

ClassOne Trident Spin Rinse Dryers are available in bench-top and roll-around single-stack units and in dual-stack configurations, for processing up to 50 substrates per batch in sizes of 75mm to 200mm, depending upon the model, bowl size and rotor used.
