BVX AerOheat Heater

Phn: 800-237-6725 

Features:

· Ultra low heat generated in cold sections.

 

· Electrical connections sealed inside of electrically isolated metal sheath.

 

· Variety of sizes and lengths

         possible for customers needs.

 

· Reduction in heat at cold end allows moisture seals to survive even in extreme process temperatures.

 

· Vacuum sealing “O” rings can survive when sealed against the BVX cold section.  Previous cold sections could generate enough heat to melt silicone and viton seals.

 

· All welded construction to minimize any possible contamination to customers system.

 

· Available in stainless steel and Inconel 600 outer metal sheaths.

 

· BVX offered as direct replacement for traditional BXX series heater designs

 

· BVX heaters have been successfully

         used at over 100W/Square inch on the   
         heated section.

 

TESTING SERVICES OFFERED AT ARI:

 

ARI’s own metallurgical laboratory offers
analysis levels that go beyond the norm.




Internal features of the cables structure are revealed with X-Ray’s that show what hides within.  ARI strives to offer you the customer the newest format of digital X-rays with on site historical storage that can be retrieved if needed in the future.  Secure FTP upload for large files that eliminates the bottle neck of email file limitation.


ARI offers helium leak testing to insure the highest integrity of our products outer sheath and any attached hardware. 

 

NIST traceable  helium leak standards are maintained to  insure our abilities to  calibrate our system to the extremes
(9 range leak standards).

 

We have high pressurization options (bombing) available for our cable (up to 5000 PSI).

Testing after such pressurization insures the integrity of the cable/heaters that we produce.

ARI’s new BVX series AerOheat heaters offers a vast improvement in heated cable to cold end efficiencyARI’s  AerOheat heaters have always provided outstanding high temperature electrical heating.  Today’s demands in semiconductors and aerospace have driven us to take a very successful product and built upon it’s current features and improve them beyond where current heaters fail. 

The new BVX series of AerOrod heaters allows the end user to focus the heat where the customer wants it.  After the heated section a cold section that extends away from the heated section provides only a fraction of the heating that previous heaters generated. 

Old to new comparison example: 
Current BXX series heaters offer a 10 to 1 ratio on heating vs cold cable.  1 Ft of heated cable that generated 50 watts would generate 5 watts/Ft in 1 Ft of the cold section cable.  The new BVX series heaters in the same application would generate only 0.5 to 1 watt of heat in 1 Ft of cold section.  Values shown are nominal values and can vary with standard tolerance ranges. 

Customer applications benefit from the focused heat in the area where they want it without introducing heat into unwanted areas.  Unwanted areas could be in the insulation barrier that surrounds the heated section, or even passing through a vacuum  where heat is not wanted on the cold section

Power connections remain much cooler when using the improved cold sections.  Previous high voltage cold sections generated excessive temperature to point where ceramic insulations were needed at the potting adapter to lead wire.  Typical moisture seals at the ends of the cold cable can withstand 250°F (121°C), and 500°F (260°C).  

Environmental seals when exiting vacuum chambers are not exposed to excessive temperature
generated from the cold ends of  the BVX series.    Typical seal temperature ratings are:

                 Buna “O” ring seals are rated for 176°F. (80°C)
                 Viton seals are rated for 356° F. (180°C)
                 Silicone “O” ring seals are rated for 400°F. (200°C). 

Do you need to go beyond what flexible seals can offer?  No problem.  Our AerOheat heaters offer a
100% sealed outer surface that can be easily be used with a conflat vacuum flange. 

Radiant heat is the best form of heat transfer in a vacuum.  Electric heaters need to be over 1000°F before metal surfaces start to radiate heat away from the surface of the heater.  Keeping that heat in the area of the process and away from the cold section of cable brings a new generation of efficiency to vacuum process heating.  

Vacuum applications act like heat traps until radiant temperatures are achieved.  Sensing temperatures from metal heater surfaces in a vacuum can also be difficult. 

 

ARI offers high temperature furnace brazing of sensors to attach thermocouples directly to the metal sheath.  Proper Sensor attachment allows the parts to remain in contact in a vacuum and not rely on radiant heat transfer.   Having that sensing point for feedback to the control system allows excellent repeatability for process control and

management.

 

The BVX Heaters can be made as direct replacements for the BXX series of cable heaters currently in use around the world.  Custom shapes and custom bend formations can be developed for your application

specific needs (see above design sketch).

 

BVX example sketch is shown below:

ARI offers heaters from 0.0335 inch O.D. &  larger.  Custom sizes and lengths are available to meet  your applications needs.   Contact our sales/engineers for any questions, or pricing inquiries. 

 

Due to the formability of the heater cable the shapes we can offer an incredible variety of shapes and watt densities from these shapes to put the heat where you need it in the AMOUNTS you need it in.   Our engineers and model makers bring years of experience into making the complex a reality in our products.
