Maintech’s dryer section solutions are designed to reduce deposits on dryer fabrics, rolls, dryer cylinders and calender rolls, helping paper and paperboard mills improve runnability, drying efficiency, fabric life and product quality.
Dryer section contamination remains a persistent operating issue for paper and paperboard mills, affecting sheet stability, drying performance, energy use and maintenance requirements. Maintech positions its technology around this specific production challenge, focusing on troublesome deposits that build up on dryer fabrics, rolls, dryer cylinders and calender rolls.
For mills, the issue is not only cleanliness. Deposits in the dryer section can contribute to sheet breaks, unstable runnability, reduced drying efficiency, quality defects and increased manual cleaning. These problems can directly affect production output, steam consumption and machine availability.
Maintech says its solutions are based on 30 years of experience, with more than 1,000 applications on over 300 paper machines worldwide. The company’s focus is on helping mills reduce dryer section sheet breaks, improve runnability, increase drying capacity and extend dryer fabric life.
The operational case for deposit control is especially relevant in paperboard and corrugating medium production, where machines often run at high speeds and where dryer section stability is central to productivity. Maintech’s published case examples refer to corrugating medium machines operating at widths of 7.2 metres and speeds of 800 to 1,000 metres per minute.
A key part of Maintech’s approach is its DSP technology, which the company compares with conventional passivation approaches in dryer cylinder and dryer fabric applications. In the case examples provided by Maintech, its DSP treatment is shown at a lower application rate than competing passivation methods, with the company highlighting improved surface conditions and chemical transfer to subsequent dryers.
The potential benefits are directly linked to mill performance. Maintech identifies reduced steam consumption and pressure, improved paper quality, defect reduction, smoother paper surface and improved moisture profile as possible outcomes of better deposit control in the dryer section.
The technology also has a maintenance and safety dimension. Reduced operator cleaning with aggressive chemicals can lower manual intervention around the machine and support more consistent operating practices. For mills facing labour constraints, tighter maintenance windows and pressure to reduce downtime, this is an important part of the value proposition.
Maintech describes its approach as a combination of chemical, equipment and application technologies. That integrated model is important because dryer section deposit control is rarely solved by chemistry alone. Application consistency, equipment reliability and correct placement on the machine all influence results.
For paper and paperboard producers, the relevance is clear: dryer section performance affects production stability, energy efficiency, sheet quality and maintenance workload. Maintech’s focus on deposit control places the company in a practical area of mill optimization, where incremental improvements can have measurable effects on daily machine performance.
