High Temperature Universal Ovens
High Temperature Universal Ovens
Front-to-back horizontal air flow accommodates virtually any oven loading without restricting air passage. Work can be shelf loaded or placed directly on the optional reinforced work space bottom. Designed for annealing, sintering, hardening or any other application where a dependable source of heated air with higher temperatures is required.
High Temperature Universal 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.
