Horizontal Air Flow Cabinet Ovens
Horizontal Air Flow Cabinet Ovens
Horizontal air flow ovens provide exceptional temperature uniformity as air flow passes heated air across each shelf level for closely controlled production work.
Horizontal Air Flow 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.
