ProJet received an order for a total 4 ProJet High Pressure Cleaners from PT. Adiprima Suparinta for their PM1. Adiprima PM3 already ordered 8 ProJet Cleaners for their PM3 in July of 2023. The value of the order will not be disclosed. The order was received in October 2023 and will delivered in Q1 2024.
The Cleaners will be supplied along with all auxiliary equipment, pumps, control panels, etc. All pumps are provided with redundant systems for maximum reliability. The new ProJet Power Cleaners will provide maximum cleanliness and permeability to the Dryer Section of PM1.
Power Cleaners for the Dryer Section
Of course, all Power Cleaners for the Dryer Section will be ProJet’s Power Cleaner 2.0, the upgraded version. The upgrade consists of a smaller cleaner head, more nozzles at higher pressure and improved vacuum/discharge system. The combination of all these improvements is an increased cleaning efficiency, exactly what FPC needed for its Dryer Fabrics.
The Power Cleaner cleans the Dryer Fabrics continuously, 24 hours a day, as long as the machine is running. Older technologies are operated in batch cleaning mode, allowing the dryer fabrics to get dirty first, losing permeability, and then trying to restore that permeability again. This leads to uneven permeability profiles over time, mostly leading to paper quality issues and more broke. The above graph shows the advantage of continuous cleaning, leading to a more stable moisture profile, less broke and longer lifetime of fabrics. Dryer fabric contamination is on the rise due to the increasing use of secondary fibres, recycling of coated broke, increasing use of sheet fillers, an increased use of recycled mill water supplies, and the increased use of process chemicals.
