Cool to the Touch
Dual Layer Shroud with Inner Stainless Steel solid layer, a radiation shield that directs the cooling air flow over the heater and an Outer Stainless Steel perforated layer that isolates hot surfaces from contact (cool touch)
Multiversal
Single Layer Shroud Solid Stainless Steel Layer, a radiation shield that directs the cooling air flow over the heater
Arctic Cast
Single Layer Shroud Vented 1/4″ thick Cast Aluminum layer – directs the cooling air flow over the heater
Blowers
No options available for this section based on your selections
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

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.
