Single Layer Shroud Vented 1/4" thick Cast Aluminum layer – directs the cooling air flow over the heater

Hinge with Barrel Clamps

Shroud is hinged on one side and secured with clamps on the other; designed for ease of installation.
NOTE: Not available on Cast Aluminum Shrouds.

Two Individual Halves

Two-Piece – used where installation space is tight or mounting is difficult
Barrel Clamps are used in sheet metal designs
Bolts are used in cast aluminum designs

Internal Support Straps

On blower mount half of shroud permits shroud to be opened for servicing without removing unit from barrel

Support U-Bolt

On blower mount half of shroud permits shroud to be opened for servicing without removing unit from barrel.
NOTE: Not available on Cast Aluminum Shrouds.

Anti-Rotate Tabs

Used only with Finned Cast-In Heaters to prevent shroud from radial and axial movement around the barrel - Tabs are cast as part of the heater (may require a Terminal Box)

Standard Single Phase Centrifugal Blowers

Tempco standard blowers feature corrosion protected sheet metal housings and impeller wheels. The quiet operation and quick response coupled with high volume unrestricted output results in a field-proven efficient cooling means for extrusion processes. Standard blowers are readily available for single phase 115V or 230V and represent the shortest delivery times.

Low-Profile Single Phase Centrifugal Blowers

Tempco low-profile 115/230V single phase blowers offer a narrower footprint than the standard blowers. The motor is integrated with the impeller so that the motor housing protrudes only slightly from the blower housing. Low-profile blowers are made of die-cast aluminum and galvanized sheet steel and are perfect for applications where space is a concern.

Universal Three-Phase Centrifugal Blowers

Tempco high-end blowers use heavy duty construction for a long service life. They are available with universal three-phase motors for 50/60 HZ operation on voltages from 202 up to 530V. They meet Cenelec standards and are IP41 or IP54 rated with class B or F insulation systems. These low noise, continuous duty rated blowers operate efficiently under higher static pressure loads than our standard blowers.

Blower Extensions

Blower extensions are available for applications where space restrictions do not allow the blower to be mounted directly to the shroud assembly.

Inlet Guard

Available for Single Inlet Centrifugal Blowers

Horizontal Blower

Blower is located at 90° or 270°
NOTE: Not available on Cast Aluminum Shrouds.

Vertical Blower

Blower is located at 0° or 180°
Arctic Cast Shroud Systems: Vertical Orientation is located at the bottom of the shroud; Custom location achieved only by rotating entire shroud system

Custom Location Blower

Blower is positioned per special customer specifications.
NOTE: Not available on Cast Aluminum Shrouds.

Finned Cast Aluminum Heater

Cast Aluminum heater is the standard heater in Tempco shroud system designs with a standard 1/4" gap between heater halves.
Bolt and nut clamping used in cast aluminum shroud designs

Vented Ceramic Band Heater

Thisvented heater was developed to provide another means of heating and cooling high temperature extrusion processes. To reduce the cost and weight of typical shroud systems, Tempco developed a low mass, non-thermally insulated ceramic band heater to work in tandem with a highly efficient stainless steel sheet metal shroud for high temperature heating and cooling extrusion processes. Forced air blowers are used for cooling. The ambient airflow enters the shroud, circulates around the ceramic heater and barrel, removes the heat from the heater and the process and exits the shroud opposite the entrance port.
NOTE: Not available on Cast Aluminum Shrouds.

Maxiband Heater

The channels in the extruded aluminum track are precisely sized to accept a .315 diameter tubular heating element and provide an excellent heat sink for rapid heat transfer and good temperature uniformity.
NOTE: Not available on Cast Aluminum Shrouds.

Power Input Terminal Box
