BCE Heaters, Feedthroughs, and Control Consoles
At BCE, we understand the need for precision and reliability in industrial applications. That's why our vacuum feedthroughs, electric heating elements, and con are designed to meet the highest standards.
Environmentally Friendly Mini Clean Flow Heater Replaces Gas Burner System
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.
- Temperature 482°C to 648°C
- Internal element must be able to withstand temperature <750°C and be electrically isolated
- 3” outside diameter, no insulation
- A sanitary fitting on the inlet with an NPT on the outlet
- A cold section on the heat source was required with fiberglass leads
- 304 stainless steel material on the heat source and vessel
- Type “J” Thermocouple able to withstand high temp at the outlet
- 480Volt, 7,000Watt (+/-10%)
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.
MEGA CLEAN FLOW Heater: Minimizing Toxic Emissions for Cogeneration
Using a small (~25HP) lean burn natural gas motor for cogeneration, our customer wanted to mitigate toxic emissions on the exhaust. The challenge is reducing Formaldehyde and Benzine output levels as well as reducing all other toxins without air-flow exposure to ni-chrome resistors.
- Exhaust air flow rates from 15cfm to 30cfm
- Inlet 2” NPT, outlet 2” NPT
- Engine loads for 25% to 100%
- Insulation of all inlet & outlet entries as well as process chamber
- Air-flow exposure to 304 or 316 stainless steel only
- Outlet temperature must be <288°C at ALL flow rates
- BCE Controllers needed for operating temp and
- 50 Meg-ohm isolation at 500 VDC
- Hi-pot 2E + 1K at 3mAmp
- ALL TESTS PERFORMED AT ROOM TEMPERATURE

SCOPE
The heater of the apparatus needed to be able to:
- Generate internal temperatures exceeding 500°C
- Ramp to elevated temperatures within minutes
- Operate at low voltage: 24V
- Sustain pressures up to 80 psi
- Assemble easily to a control valve
- Remain operable at a motion of 10 g
- Allow for acute temperature control
- Have a low mass design for efficient heat transfer
- Be compact; allowing the assembly to remain within a 10” envelope
BCE’s MCF heater provided the optimal solution to this design challenge. During pre-heat with no air flow, the internal temperature of the MCF reached 320°C. After an 80 psi air burst and temperature drop, the low mass of the heater was able to achieve an internal temperature of 505°C in just under 90 s during the heat effect. This greatly surpassed customer expectations. Not only was its compactness an asset in maintaining the dimensional restrictions, its unique design with NPT fitting assembled easily to other components. Moreover, the built-in thermocouple type K offered precise temperature monitoring for this sensitive application. Finally, its robust design allowed for continuous operation under the most strenuous pressures and motion.

A Mini Electric Heater for Clean Flowing Gases
The solution? A mini “process air” heater.
These heaters are designed so that the stream of air is heated by passing over an enclosed heated metal surface rather, than directly over resistance elements. This prevents contaminants from entering the flow of gas.
- Designed for applications where streams of high temperature, clean air is needed.
- Air flow passes over an enclosed heated body; not exposed to ni-chrome resistive elements.
- Constructed of 304 Stainless Steel (other material is available).
- High temperatures, ranges and temperature sensors are available.
There are many uses for these clean air process heaters. Some general applications are laminating, drying, baking, shrink fitting, plastic welding, soldering, preheating and metalworking, and packaging.
More specific industry uses are:
Aerospace:
- Combustion testing
- Flow simulation
- Component stressing
- Curing adhesives
- Fuel cell testing
- Paperboard sealing
- Heat shrink installations
- Forming
- Curing adhesives
- Sterilizion
- Pharmaceuticals

| Examples of air heaters (click for larger view) |
You may want to consider an inline "air process heater".
These fabricated (usually custom) electric heaters are self-contained, provide inlets and outlets, wiring, sensors to measure internal temperatures, and are available in a variety of materials.
Air Process heater provide hot air and gas up to 1000oF (540oC) with infinite control by varying the voltage and air velocity supplied.
Units are fitted with a tubing “T” for convenient power lead outlet, while larger diameters can be supplied with post terminals on the sheath for direct electrical connections.
Designs can accommodate male or female NPT threaded fittings, hose adaptors, flanges, or custom fittings to your specifications.
