PERFECT
RADIANT® TREATER
The Litzler
Perfect Radian® is the next generation of radiant treater. It
advances proven radiant plate technology using electric
energy. This is a major operating and process advantage as it introduces
a clean, safe, reliable energy source with proven radiant technology
for today’s demanding product quality.
How Does It Work?
Radiant heaters in a sealed chamber heat the Perfect Radiant® Plate.
The patented plate precisely radiates energy to the web for even
cross-web treatment.
The oven has three process components:
- Entry
and intermediate components
- Final
zone
- Solvent
removal (purge air)
Entry
and Intermediate Zones
The
zone(s) features low temperature (up to 480°F/250°C) radiant energy
to heat the rigid stainless steel Perfect Radiant® Plate. The radiating
heat is efficiently absorbed by the
web based on the principle of longwave infrared in the electromagnetic
energy spectrum. This
electric radiant technology provides adjustable cross-web temperatures,
resulting in uniform cross-web solvent evaporation and curing.
Operation
-
Electric
heaters heat the Perfect Radiant® Plate which isolates the
heaters from the treatment chamber
-
Perfect Radiant® Plate evenly heats the web
-
Cross-web
zoning gives perfect webtemperature
profile
-
Heater
technology allows quick heat-up time and temperature changes
Final
Zone
The
final zone features eleven cross-web zones with sealed radiant
heaters. These cross-web zones offer infinitely controllable
cross-web accuracy to adjust final product properties such as
melt-viscosity.
The heater’s rapid response and precision supports an
optional closed loop system with gauging or resin cure monitoring.
Operation
Purge
Air
Solvent
concentration is controlled by a purge air system introducing clean,
fresh, heated air at the top of the oven and exhausting it through
the bottom to the oxidizer. Heat recovery from the oxidizer is
the heat source for the clean purge air.
