High Temperature 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.
