Tempco’s Air-Cooled Shroud Systems are highly engineered heating and cooling systems that offer an efficient means to heat and cool the barrels of extruders. These systems are self-contained and can be supplied as ready-to-go, requiring minimum labor and installation cost, and drastically reducing downtime and maintenance upkeep compared to conventional liquid cooling and heating cast-in band heaters.

Inner Stainless Steel Solid Layer Radiation shield that directs the cooling airflow over the heater and holds in heat to reduce energy use
Outer Stainless Steel Perforated Layer Isolates hot surfaces from contact (cool touch) for operator safety
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 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.
Solid Stainless Steel Layer Radiation shield that directs the cooling air flow over the heater and holds in heat to reduce energy use
Tempco’s Multi-Versal extruder heat/cool systems are designed for efficient heating and cooling. A highly adaptable single-layer shroud, they are suited for retrofit and/or new applications regardless of the type of barrel band heater being used. These shroud systems can be used with 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 casting and distributes it evenly over the entire cross-section of the zone.
This rugged shroud design is recommended for installations where the shroud system could be exposed to physical damage, such as instances where the extruder barrel is low to the ground. It is suited to work with Tempco’s specially designed finned cast-in aluminum heaters and cannot be used on any existing finned cast-in heaters.
The Arctic Cast shroud features a vented 1/4" thick cast aluminum layer for durability. The cast-in heaters are designed with a large fin surface area to maximize cooling efficiency. The blower port directs inlet air to the hottest part of the heater, distributing it evenly over the entire cross-section of the zone.
