Class 100 Clean Room Cabinet Ovens

For processes where eliminating particle contamination is required, such as sterilization, depyrogenation, curing and drying. These electrically heated ovens feature a low particle count Class 100 atmosphere inside. Exterior construction minimizes particle generation. Heavy duty units equally suited for pharmaceutical or industrial applications.

Class 100 Clean Room Cabinet Ovens Model Specifications:

CAUTION:  Ovens processing combustible material are required by National Fire Protection Association 86 Standard for Ovens and Furnaces (NFPA 86) to have a fire suppression system.  If flammable solvents or vapors are present in an oven, OSHA requires conformance with NFPA 86 Class A Oven requirements.  A powered forced exhauster and other non-standard safety equipment must be added.  See Class A Oven Equipment for Solvent Processing resource page, reference our FAQs or contact us us for more information.

    Electrical modification adding an SCR Power Controller. Features:

    •Silicon controlled rectifier power controllers are completely solid state industrial controllers that ensure precise proportioning of electric power to the heating elements.

    •Oven temperature is maintained smoothly and evenly over the entire temperature range of the unit.

    •SCR power controllers minimize maintenance, as there are no moving parts or electrical contacts to wear out.

    •Heating element fatigue is reduced since the elements do not cool between releases of electric power.

    •Zero voltage firing, including the first one half cycle of voltage, minimizes radio frequency and electromagnetic interference.

    •Transient voltage suppressor networks are included, and the units are provided with protective fusing.
