The current generation HTI Spectra HE ultra drying system from Heat Technologies Inc., Atlanta, has been installed at a customer plant to dry heavy water- and solvent-based coatings.
The approximately 4' long system fully replaced the customer’s existing 56' dryer.
Yet, at the same coating and adhesive coverage, and for water-based
applications, the Spectra HE provided the required drying without use of
external heaters, says the manufacturer. Average operating temperature of the
hot air delivered by the system is lower by about 50 to 70°F (28 to 39°C) than
the hot air delivered by the existing system.
Other applications for the drying systems include critical surface control
materials and components; food processing; printed electronics; high-barrier
laminations; papermaking and converting; cold-seal applications; molded fiber;
and substrate cooling.
