Walk-In Ovens Horizontal Air Flow Rear Mounted Heat Chamber

These ovens produce heated air blown horizontally across the work space between full coverage duct work. For shelf truck loading applications with densely loaded shelves, solid bottom trays or flat sheets where heated air can only pass sideways above and below each level. Rear heat chamber for easy handling, low profile equipment.

Walk-In Ovens Horizontal 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.
