Change over from one size of tubing to another required moving the existing hot wall furnace curing system to gain access to the extruding head
Wasted Time
The existing hot wall furnace had a very slow response time and took a minimum of two hours to heat up and stabilize when changing the temperature for a different product.
Wasted Energy
The long heat up time for the existing heat source used a significant amount of energy without producing any tubing.
Poor Quality
The limitations of the existing heat source did not consistently produce quality tubing.
Limited Space
The manufacturer needed to reclaim some of the floor space used by the 12 foot (3.7 meter) long existing heat source for other processes.
Solution
Heat
A Model 4069-12-38 Parabolic Clamshell Heater provided the precise amount of heat needed to cure the silicone tubing.
Vertical Installation
Using vertical burn lamps, the Parabolic Clamshell Heater was installed vertically.
Power Control
The Parabolic Clamshell Heater was controlled with a Model 664F Phase Angle SCR Power Controller.
Instant On/Off
The Parabolic Clamshell Heater heated up and cooled down instantly based upon signals received from the SCR Power Controller.
An optional quartz tube liner was inserted in the Parabolic Clamshell Heater to keep its reflectors clean and address the manufacturer’s concern that a break in the line would cause a fire.

Benefits
Compact Heat Source
The Model 4069 Parabolic Clamshell Heater did not have to be moved when the extruding head needed to be accessed.
Increased Production
The responsiveness of the Parabolic Clamshell Heater allowed the manufacturer to increase production output.
Saved Energy
The instant on/off capabilities of the Parabolic Clamshell Heater did not require significant amounts of energy to be consumed for heat up.
Improved Quality
The uniform heat applied by the Parabolic Clamshell Heater consistently produced quality tubing.
Reclaimed Floor Space
By installing the Parabolic Clamshell Heater vertically on the line, the manufacturer was able to reclaim valuable floor space for other processes.
