Hudson Falls Leverages Manufacturing Knowledge for High Pressure Paper Machine Dryers
GL&V’s dryer foundry in Hudson Falls, NY has been manufacturing paper machine steam dryers and high quality iron castings for 157 years.
Since 2005 we have been developing dryers suitable for higher pressures than the typical 125 or 150 PSI (8.6 to 10.3 Bar) ratings found on most North American paper machine dryers from the 1960’s and later.
Higher pressures are enabled by stronger alloys in both gray and ductile iron grades with the incorporation of stress relieving. Since our initial development of high pressure dryers began in 2005, nearly 300 dryers with ratings above 160 PSI have been built, with 175 PSI (12 Bar) being typical and some as high as 200 (13.7 Bar).
Higher pressure dryers enable customers, particularly those making packaging grades, to utilize increased temperatures for higher production speeds without increasing the number of dryers in the section.
