Large Capacity Bench Ovens
Large Capacity Bench Ovens
Low cost, large capacity Bench ovens for shelf processing at temperatures to 400°F. Designed to handle a wide variety of applications such as baking, curing, drying and preheating.
Large Capacity Bench 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 our contact us us for more information.
