High performance compact dryer for the paper industry
Spooner Industries
Developed in response to the industry's requirement for a high performance drying system with a small footprint, the HPC dryer combines web handling and the mass transfer capabilities of a conventional flotation system to achieve the heat transfer capabilities and compactness of a typical Infra Red system. The web is supported throughout on a dynamic air pressure pad with high clearance, achieving non-contact web handling. This makes the system effective over a wide range of processes and substrates.
The Spooner float nozzles are located above and below the web path and supplemented by an equal amount of air impingement nozzles.
The configuration creates twice the heat transfer of conventional air flotation dryers.
Spooner HPC Technology provides:
* Drying of both low and high tension webs
* Evaporation rates of up to 200kg/m2/h achieved
* Unlimited operating widths
* Operating temperatures up to 450oc
* Operation nozzle velocities up to 70 m/s
* Unlimited machine speeds
* Variable re-circulation
