Temperature Uniformity of Spectra HE™ Ultra Drying System

During one of HTI’s recent installations of heavy coating on temperature-sensitive films, a temperature uniformity and distribution across the web were measured and documented. The thermal image shows difference in temperatures on the web operator side, the middle of the web, and the drive side, does not exceed 1ºC. All measurements were taken at the exit of the HTI Spectra HE™ Ultra dryer (shown on the right hand side of the image, web is moving from right to left).

HTI delivered three complete drying systems for drying 3D products, such as single use food containers, coated with barrier food grade coatings.

Each dryer system is an organic part of a complete production line.   It is capable of producing up to 150000 products a day (24h)
