Many of you have asked how we are doing here in Bend, Oregon, because of all the fires on the US West Coast. Thank you for your concern! We are all OK.
Here's a live view of the fires' status.

Water Vapor Desorption Products

UVC-based and IR-based water vapor desorption / oxidative hydrocarbon removal systems for vacuum chambers.

Get more information...

RBD's desorption products utilize shortwave IR, and UVC radiation to desorb layers of water vapor in vacuum chambers without the intense heat of IR or a radiant bakeout. Using UVC to desorb water vapor is ideal for chambers that have Viton O-ring seals, which pump down in the range of the low 10-6 to low 10-7 Torr. Benefits include faster pump down times and a lower ultimate vacuum.

For more information on water vapor and it's effects on vacuum chambers, please see this collection of articles (compiled by Normandale Community College) by the late Phil Danielson (formally of The Vacuum Lab).


VB Series

VB Series

The VB Series of vacuum bakeout packages are designed for systems that can take the heat of shortwave IR. High-power infrared heating effectively removes water vapor from vacuum chambers.

The VB-1 operates on 120 VAC, and the VB-2 is available for 230 VAC.

The IRB-600 IR Emitter and BC-3 Bakeout Controller can be purchased separately.


The BC-3 Bakeout Controller provides total control of your vacuum chamber bakeout process. It not only controls the power to the heat source, it also uses thermocouple feedback to regulate the temperature of the vacuum chamber


The IRB-600 Infrared Emitter Assembly provides 600 watts of shortwave infrared heating to the inside of vacuum chambers to effectively remove water vapor from the chamber walls.




UVB-100 Chamber


The UVB uses UVC radiation to desorb water vapor without heat. The emitter extends into the vacuum chamber.

Flange Mounting Options
The UVB-100 comes standard with 2.75 CF or NW40 (K150) KF mount.
Other flange mounts are available on request.





The miniZ is ideal for solving water vapor problems in compact vacuum chambers such as the Kimball Physics Multi-CF line of spherical chambers, mini ALD chambers, pressure cells and load locks.

Remote Control Options

The miniZ power supply is simple to use – just turn it on! A remote ON/OFF option is available if you want to operate the miniZ by a process controller or set point.
