Heating Solutions for the Medical Device OEM

Product Announcement from Thermal Circuits, Inc.

The medical electronics industry demands precise solutions to highly sensitive applications. Thermal Circuits, Inc. etched foil heaters provide the OEM with the inherent advantage to distribute wattage infinitely and exactly. Combining this feat, with Thermal Circuits' skill in material science and the industry’s broadest selection of element and dielectric materials, often yields a competitive advantage for the OEM.
Thermal Circuits etched foil heaters are used in blood analyzers, dialysis instrumentation, DNA analysis, genetic testing systems, invasive probes, life support fluid warmers, sterilizers, tissue processors, transportable incubators, thermal cyclers, and hybridization ovens.
 Whether or not an application evolves into a final product, the OEM’s scientists, engineers and managers can be assured that Thermal Circuits team of application engineers are the best choice to meet their individual design challenges. Through research, development and innovation, Thermal Circuits provides effective solutions incorporating conductive surface heaters, convective air/gas heaters, and infrared heater assemblies.

Thermal Circuits Inc is a manufacturer of surface heaters, air heaters, molded heaters, heater assemblies, and infrared panel emitters. We service a wide variety of markets and geographic areas and, through continuous quality improvement, strive to maintain world-class leadership in all aspects of our business.

"Firsts" from Thermal Circuits continued during the 1970's and 1980's. We designed, prototyped and produced heaters and assemblies for the first etched foil-heated cafeteria food service stations, infant incubators, hospital warming cabinets, automobile side-view mirrors, kitchen electrics(mini-skillets, deep-fat fryers), and personal care appliances(mist hair setters, styling wands).

This growth prompted the construction in 1996 of a single-storied, 52,000 square foot building and remains Thermal Circuits' home. Still in Salem, the company is owned by its corporate partners and is the anchor company in a newly-developed industrial park. This facility is state-of-the-art and second to none.  Due to continuing growth, in 2017 and 2018 Thermal Circuits expanded its manufacturing and office spaces to 88,000 square feet.

Core Competencies:

A “solution” designer and manufacturer of custom, etched foil heaters and assemblies, would welcome the opportunity of creating an affordable heater designed to your application’s requirements.

Our core competencies for these conductive, convective and radiant heaters include:

  • Application Engineering that is responsive and experienced. You can be assured that we will provide an optimal, reliable solution. Let us help you turn your company’s opportunity into a competitive advantage.
  • Thermal Uniformity is attained by varying the heater’s watt density, thereby, compensating for heat losses.
  • Thermal Responsiveness is a function of the heater’s low mass. Heating and cooling are virtually instantaneous.
  • Repeatability through Thermal Circuits’ photo etch process that sustains part-to-part consistency.
  • Innovative Manufacturer

    -Recognized for using the broadest range of materials

    -Dielectrics compatible with integration and challenging environments.

             -Element/alloys developed for increased capabilities and lower costs.

  • Integrated Sensors

             -Thermistors, RTDs, semiconductor-type, thermocouples, thermostats and thermal fuses.

  • Turnkey Assemblies

              -Metalwork, heat sinks, wire harnesses and flex circuits.

  • Space and Weight Efficient

               -As thin as 0.004”.

  • Energy Efficiency

               -70% of the surface area is covered with an active element. This enables the element to run cooler and with longer wavelengths of light, which transfers heat more effectively.

               -The etched foil element’s inherent low mass has less thermal inertia, which enables lower operating costs.
