effectiveness. A Filtermist condenser can also be fitted above the wash section for the collection of oil charged water vapour. The drying section of a typical two stage machine is fitted with a full width overhead air knife that can be adjusted to accommodate different component heights and angled to shear off as much residual moisture as possible before entering the inline heater box, operating at 110°C. Parts exit onto a 500mm out-feed extension fitted with a photo electric cell to stop the conveyor when the basket reaches the end.

Washing is achieved in a high-pressure spray-washing chamber with the 100 l/min stainless steel vertical pumps flushing wash solution through directed wash jets. The stainless steel honeycomb belt can take a maximum belt loading of 100kg of components, and provides good access for

Optional extras include an auto-dosing unit fitted to the wash tank to maintain accurate wash strength solution. An external Guyson tramp oil separator can remove the worst excesses of oil contamination from the cleaning solution, thus extending the cleaning solution life and maintaining its
