Tempco Custom Heater Manufacturing

Capabilities IconOur CapabilitIes

Tempco's design and manufacturing capabilities allow us to produce the highest quality Electric Heating Elements, Temperature Sensors and Temperature Control Products.


CNC Lathes with Automatic Barfeeders

Need a custom fitting for your application? No problem! Tempco streamlines the design and manufacturing process by making our own fittings with our 12 CNC Lathes.

Foundry Melting Capabilities

Our electric reverb and induction furnaces are used to minimize gas inclusion into the molten metal, thereby producing a denser, higher quality casting.

Roll Reducing Mill and Exo-Gas Annealing Furnace

Elements are fed into the roll reducing mill to compact the MgO insulating powder. After rolling, the elements are annealed in the conveyor belt furnace seen in the background.

CNC Machine Shop

When a tolerance or geometric shape cannot be achieved as cast, we utilize our full service state-of-the-art machine shop. Our CNC machine tools include our lathes, 12 CNC Mills and Boring Mills that can perform all of the precision machining a design may require with repeatable accuracy. We also utilize our machine shop to build and maintain permanent mold tooling for our Casting processes.

Waterjet Cutting Machine

This machine is used across many of our product lines to cut sheet metal for custom panel designs, band heaters, plates for non-pressure flange heaters and other custom heater designs.

Sheet Metal Fabrication

Along with the waterjet, additional Sheet Metal Fabrication machines Tempco utilizes in our manufacturing processes are:

  • Fiber Laser
  • CNC Turret Presses
  • CNC Press Brakes

Filling Machines

Our carefully researched manufacturing methods include tubular heating element filling machines that allow us to methodically fill the heating elements with the MgO insulating powder.

In-House Welding Professionals

We use Manual Welding, Heli-Arc Welding and Brazing and Robotic TIG Welding in our manufacturing processes.

Pattern Shop

Our In-House Pattern Shop builds and maintains the wood or plastic patterns required to produce castings with no bake sand molds.

cULus Certified Panel Shop

We offer general purpose or custom engineered power control panels built in our certified shop, backed by over 45 years of experience in the process heating industry. We can meet all of your requirements from the simplest single zone panel to the most complex thermal loop system.
Our Panel Shop Certifications include the following cULus Listings:

Tilt-Pour Gravity Feed

When medium to high volume Aluminum cast-ins are produced, the Tilt-Pour Gravity Feed is used.  It will accommodate simple shape castings and moderately complex shaped castings, producing good dimensional accuracy and surface finish.

  • Ordinary Locations - Safe Area:  UL508A File # E307875  (NITW, NITW7)
  • Intrinsically Safe:  UL698A  File # E364504   (NRBX, NRBX7)  NFPA 70
  • Hazardous Locations:  Pressure-Purge, Explosion Proof UL1203  File # E364503  (NNNY, NNNY7)  NFPA 496

No-Bake Sand Molds

This process for low-volume Aluminum, Bronze and Brass Cast-Ins is ideal for large, irregular shapes and thermal platens.

Our Employees

Perhaps our most important "capability" is our expert and detail-oriented work force. Much of the custom manufacturing, like the assembly and wiring of the custom E-mitter panel you see here, cannot be done without our dedicated employees.

Additional Manufacturing Capabilities:

  • Ceramic Molding
  • CNC Bending
  • Coil Winding
  • Induction Brazing
  • Kilns
  • Plasma Cutters
  • Swaging Machines
  • Vulcanizing

Hydrostatic Pressure Testing

To ensure the quality of our Process heaters, we can perform integrity testing of welds on our flange and screw plug heaters.

Heater Life Cycle and Materials Testing Lab

Let our engineering team assist you in determining what will best suit your application by utilizing our life cycle and materials testing lab.
