For practical purposes, ITAR regulations dictate that information and material pertaining to defense and military related technologies (for items listed on the U.S. Munitions List) may only be shared with U.S. Persons unless authorization from the Department of State is received or a special exemption is used. U.S. Persons (including organizations) can face heavy fines if they have, without authorization or the use of an exemption, provided foreign (non-US) persons with access to ITAR-protected defense articles, services or technical data.

RBF is a true proactive periodic preventative maintenance and repair program. This program is designed to obtain critical operational information in regards to chamber performance. This monitoring system catches problems and allows repair scheduling before they become failures. This program greatly reduces unscheduled downtime and addresses the customer's requirements for critical processes. A detailed service report of action items is issued after the periodic maintenance is completed and required repairs are scheduled based on a three Tier priority level. This allows the customer to address the immediate need and schedule most repairs based on their production/engineering schedule. The customer controls the downtime.
