A new web offset dryer launched by Goss International boasts the promise of cost savings and environmental benefits.
The Ecoset dryer, based on the existing Goss Ecocool technology, includes design elements that can reduce energy consumption and emissions by 50 percent or more, claims the company.
The key is the elimination of the cooling section within the dryer, which traditionally pre-cools the web prior to the chill rolls to reduce solvent
condensation. Due to the cooling capability of Goss’ small-diameter Ecocool chill rollers, a web can move directly from drying to chilling
without condensation. With no cooling section, the overall intake of cold air into the dryer is reduced, with a subsequent reduction in gas consumption and emission.
“We estimate that an Ecoset dryer could reduce energy costs by up to $100,000 per year versus an Ecocool dryer, based on current average energy
rates,” according to Bas Klaver, product manager with Goss International.
“The potential reduction in carbon dioxide emissions due to lower gas consumption is estimated at 364 tonnes per year for a 64-page press and 283 tonnes per year for a 24-page press,” he adds.
The Ecoset dryer has a smaller footprint, and it’s currently available for all web widths between 1460 mm and 2860 mm. Existing Ecocool installations can be upgraded to the new Ecoset concept.
