Profile: MDC Vacuum Products, LLC specializes in producing vacuum components. Our products include flanges & fittings, valves, roughing components, viewports & glass components, electrical & fluid feedthroughs and chambers. The Del-Seal™ CF flanges are 100 percent Conflat® compatible metal-seal flanges suitable for the UHV applications. Its CF metal seal flanges are available in a wide range of sizes that can accommodate 1/8 to 14 inch tube diameters. For tube sizes above 14 inches and up to 24 inches in diameter, our wire seal flanges are recommended. Molecular sieve traps containing type 13X synthetic zeolite effectively prevent oil backstreaming and trap water vapors at room temperature. Type 13X zeolite will adsorb molecules with critical diameters up to 10 angstrom. A valve should be used to isolate the evolved gas from the system during the bakeout cycle. During bakeout a mechanical pump removes the evolved gases from the sieve trapping material. To minimize down-time, bakeouts can be conducted, with the aid of a timer, during system off-hours. Oils trapped by the sieve material will not be evolved by baking. Periodic replacement of the sieve material is required whenever the sieve material exhibits evidence of hydrocarbon saturation as determined by empirical observation. The sieve trapping material is easily replaced through a port fitted to the top of the trap. Molecular sieve traps can be mounted in a vertical or horizontal position. A trap's built-in heater requires customer wiring to a 115VAC wall outlet. Once turned on, the heater reaches and maintains a self-regulated and constant 150°C temperature. Bakeout time depends on the amount of water vapor loading of the zeolite and can range from 4 to 12 hours. Standard chamber line features spherical chambers, D-shape chamber, horizontal cylindrical chambers in 304L stainless steel or 6061-T6 aluminum and box.
