Walk-In Ovens Combination Air Flow Rear Mounted Heat Chamber

These ovens produce heated air that is provided from full coverage supply duct work at each side of the work space and sweeps upward through the load to a return duct at the top of the work space. Ideal for large parts placed directly on oven floor or loaded on a truck. Rear heat chamber for easy handling, low profile equipment.

Walk-In Ovens Combination Air Flow Rear Mounted Heat Chamber 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.
