Liquid Cooling Cast-In Band Heaters vs. Cool TO-THE Touch Air Cooling Shroud Systems
Liquid Cooling
A Change Is In The Air
Up to now Liquid Cooling Cast-In Band Heaters have been the
predominant method of controlling the melt temperature of
extrusion barrels. Although effective in removing heat from
the extrusion process, there are a number of drawbacks that
are primarily maintenance related.
Extruders using liquid cooled Cast-In Heaters can be subject
to unpredictable and untimely failures of the cooling tube
assemblies, resulting in extremely costly downtime to the
processor. Inherent maintenance problems include stress
corrosion cracks, linear thermal expansion of the heater body,
and clogging of the tubes due to accumulation of mineral
deposits. Additionally, Liquid Cooled Cast-In Heaters require
an expensive cooling tower or heat exchange system,
extensive plumbing systems and labor for installation.
Tempco-designed air cooled systems have evolved
considerably and become more thermally efficient as a result
of geometric changes and implementation of sophisticated
shrouding and air flow techniques. Optimized direction and
ducting of airflow, coupled with selection of the proper
blower CFM, are important to ensuring that the air cooling
technique removes the proper amount of heat from the
extrusion barrel. Air Cooled Cast-In Heaters are virtually
maintenance free and therefore, when properly installed and
applied, have the capability to far outlast and perform their
liquid cooled counterparts.

Cool TO-THE Touch Extruder Heat/Cool System
Tempco's Cool TO-THE Touch extruder heat/cool systems are
custom engineered to provide optimal heating and cooling while
providing personnel safety with a Cool Touch perforated outer
layer. These systems are designed with finned cast-in heaters that
optimize overall system efficiency.
The reflective inner layer of the shroud decreases the heat-up
cycle, reducing energy consumption. The "maxi-flow" unrestricted
blower port directs inlet air to the hottest part of the casting and
distributes it evenly over the entire cross section of the zone.

Multi-Versal Shroud System
®
Multi-Versal Extruder Heat/Cool System
Tempco's Multi-Versal extruder heat/cool systems are designed
for efficient heating and cooling. The shroud systems can be used
with a many styles of band heaters. Due to the single layer design,
the Multi-Versal shroud system has a low profile OD.
The reflective interior of the shroud decreases the heat-up cycle,
reducing energy consumption. The unrestricted blower port
directs inlet air to the hottest part of the heater and distributes it
evenly over the entire cross section of the zone.
2 – Multi–Versal Construction
Multi-Versal Extruder
Solid, Stainless Steel
Single Layer Shroud
Usage Requirements
A highly adaptable single layer shroud,
suited for retrofit and/or new
applications regardless of the type of
barrel band heater being used.
