ATEX Pan Washers

Rotajet manufactures a range of mobile mixing vessel washing machines, the machines are used for washing vessels both internally and externally.

ATEX Pan Washing Solutions

The machines typically use heated an alkaline detergent to wash the vessels, after caustic washing the vessels are then rinsed with water and flashed dried to be put back into production, ready for a new batch of ink or paint to be mixed.

Loading the Vessel for washing

The contaminated vessel is wheeled or loaded onto the Rotajet PW1500 vessel washer, the operator then closes the interlocked safety door. This allows the vessel to be raised into the cleaning position and also closes and seals the door for safety.

Cleaning Cycle of the vessel washer

Once in position, the operator starts the washing cycle, the initial wash stage uses a heated (65-70°C) alkaline detergent to remove the surface contamination from the mixing vessel; typically the cycle time is around 10 minutes for standard paints and inks. For harder to clean contamination butyl glycols or dibasic esters can be used to increase the cleaning performance of the washing media.

The wash solution is held in a 2000 litre conical tank located at the rear of the machine. When the washing cycle is taking place, the used wash solution is filtered and returned to the wash storage tank for reuse in the Rotajet vessel washing machine.

After the wash cycle, the machine automatically rinses the vessels using a water rinse; this removes any caustic residues that may be present. The rinse solution is stored in a 1500 litre conical tank at the rear of the machine. The used rinse solution is filtered and returned to the storage tank for reuse in the Rotajet vessel washing machine. PH probes can be added to the storage tank to monitor pH.

Drying the mixing vessel

After the wash and rinse cycle the extraction fan on the Rotajet vessel washing machine engages and the vessel flash dries. The vessel is automatically lowered and the operator removes the clean dry vessel and replaces it with a contaminated one, and starts the cycle again.

Typical users of this machine are:

  • Paint manufactures:    ATEX washing paint or raw materials from mixing vessels for reuse.
  • Ink manufacturers:      ATEX washing paint or raw materials from mixing vessels for reuse.
  • Resin Manufacturers:  ATEX washing resin or raw materials from mixing vessels for reuse.
  • Adhesives:                   ATEX washing resin or raw materials from mixing vessels for reuse.
