Infusion Preheater

Upgrade Application

Applicable to all Singlefacers and Corrugated Preheat Applications

Upgrade Description

The Infusion Preheater is designed to increase productivity and provide a solution to many runnability problems resulting from insufficient heat transfer. The preheater package is compact and easily installed. The heating element consists of a stationary 20” diameter shell which is heated by high pressure and low pressure superheated steam. Liner passes over the heated shell surface in a frictionless manner and is heated by the hot steam film. The amount of heat transferred is essentially independent of web tension and the maximum paper temperature achieved is around 212° F. even at low speeds. Further, the paper moisture remains essentially the same throughout this heating phase.

Upgrade Benefits

•  More rapid transfer of heat to the moving paper surface
• Easily installed - small compact package
• Self-limiting temperatures paper will not overheat even at low speeds
• Preserves liner moisture for improved warp control and reduced liner cracking
• Paper heating independent of web tension
• Higher operating speeds
• Improved warp control
• Eliminates blisters during web splices caused by low tension
• Reduces liner cracking caused by over-drying
  

Installation Description

This unit can be hung from the bridge, floor mounted, or installed on top of the existing stationary preheater
