The BCE Hem Sealed Heater™ incorporates both the cartridge heaters’ wire wound resistive element encased in a metal sheath and the vacuum compatibility of a feedthrough. Furthermore, the BCE proprietary epoxy seal allows the heater to pass strict electrical tests ensuring the purity of the dielectric materials and hence, preventing shorting. The BCE Hem Sealed Heater™ outperforms as heat flows uniformly from inside the cartridge directly to the heated bodies.


A very compact, fast responding electric heating element for liquids and gases for all clean, fuel cell, bio-med, laboratory, food, and pharmaceutical applications. Designed for heating of clean gases and liquids with the medium not exposed to chromium flakes or electrically charged resistors. High wattages and various voltages are available.


Industrial process tools used for memory devices, transistors, crystal silicon, microprocessors, photovoltaic (PV) cells, and thin film PV cells. All these applications required a shrewd knowledge of temperature, BCE continues to innovate and provide customer specific thermal solutions that are critical to next generation equipment and processes. Electric heaters that provide a very high level of temperature uniformity across the semiconductor wafer to ensure consistent quality plus highly repeatable and efficient wafer processing.

  • Immersion heaters using 316 Stainless Steel
  • Alumina heaters
  • Pedestal heaters
  • Bake/Chill Platens
  • Vacuum Ring Heaters
  • Bake/Chill Pedestals
  • Brazed in Vacuum Chamber Heaters
  • Clamp-in Coil Heaters


Heaters that are used in the electron ionization in gas chromatography and mass spectrometry to ionize and fragment analyte molecules before mass spectrometric analysis and detection. A typical electron ionization source exposes the analyte, under vacuum to a stream of thermionic electrons produced from a resistively heated-gas weldment assembly.  Gas heated up to 450°C.  Built-in thermocouple for precise temperature control is incorporated in the gas body assembly.


The SMARTFLOW liquid heater with its Reservoir Design is for applications where fast heating of liquids is required. All parts exposed to liquid flow are constructed of 304/316SS (other materials available). All units have built-in Type J or K TC with potential of added adapter for outlet flow. Wetted parts constructed of 316 stainless steel with liquid flow passing over an enclosed heated body. All threaded fittings are available such as NPT, SAE, BSP, VCR & more.


This specialized category of electric heating element is designed to provide extremely uniform temperature profiles across the length of the GC column. This uniformity accommodates a stable temperature environment for the capture of repeatable and consistent data between runs. Gas chromatograph heaters allow for very precise temperature ramping and set point control to very tight tolerances. This is critical because the slightest fluctuation in column temperature during analysis will have significant effect on analysis outcomes.
