Wishing you a happy holiday and a wonderful New Year.
Best wishes from everyone at BCE.
The application involved using environmentally friendly electric heat replacing a gas burner type system. The engineering request was to conform to a direct replacement 3” stainless tubing while utilizing BCE’s Mini Clean Flow In-line design. The challenge was building the right inlet and outlet fittings in-line for a seamless change in the air heating process (gas to electric). Electrically isolated elements in the air stream were required with a high temperature thermocouple assembly near the outlet.
BCE produced a highly effective Mini Clean Flow heater meeting the delta “T” requirements during the final testing. We were able to pressure test the part to 90PSI @ 20⁰C-25⁰ without any visible leaks in the weld or braze joints. A thorough quality inspection was completed on the heater source with final cleaning using isopropyl alcohol and dry air.
With the existing chip shortage, an atomic layer deposition (ALD) application up to 360⁰C was the focus of the latest BCE Vacuum Heater Chuck. A compressed assembly was used with many vacuum holes and grooves in the bottom plate to allow the gases to escape during pump down of the vacuum chamber. No surface anodizing was required.
BCE produced a highly effective vacuum heater which reached an atmospheric temperature of 360°C in under 30 minutes. The reduced mass on the bottom plate provided proper gas elimination with a quicker initial ramp time. Due to this decreased ramp time in atmosphere, a reduced wattage may be an option for the next iteration of the 450mm Vacuum Heater Chuck.
Sunrods have a unique hot tip that allows you to reach any part of your operation that requires heat.
When activated, the split sheath design of SunRod forces its opposing legs to extend into contact with the surrounding bore for optimal heat transfer resulting in reduced operating temperature and an extended operating - by up to five times!
SunRod elements contract when de-energized, breaking contact with the bore and allowing slide-out removal. SunRods are never going to seize!
You may now apply heat whenever you want! Drill a small bore to the area that requires heating and insert a hot tip SunRod.

The new Vertex line of feedthroughs was born out of the necessity of making right-angle feedthroughs robust enough to handle the high vacuum requirements, voltage, amperage, pin dimensions, and challenging space constraints. BCE responded with the Vertex feedthrough.
The feedthrough utilizes precise beaded welds and multiple cure times of the BCE epoxy. After each cure, a vacuum leak test is performed to spec, ensuring feedthrough integrity. Chemical cleaning is BCE’s standard procedure for the Vertex.
In a recent test the BCE Copper Molybdenum (CuMo) Vacuum Heater Chuck performed admirably past its stated rating of 850º C up to 900º C during ramp-up and heater stabilization.
The BCE Copper Molybdenum capability of 850º C clearly outperforms aluminum heater chucks temperature threshold of 450º C by a large margin, and also provides the benefit of more uniform heat distribution.
