Class A Batch Oven
Blue M Class A Batch Ovens are mechanical convection electric chambers that include safety features recommended in NFPA Bulletin 86 as standard for the processing of alcohol, solvent mixes or other volatiles. The design of the Class A oven chamber concedes that the element temperature may be well above the auto-ignition point of some flammable materials, but this is mitigated by maintaining a non-explosive mixture through the use of higher than normal exhaust rates. Increased heating element kW compensates for this exhaust factor. A negative pressure is maintained in the work chamber, ensuring that all hazardous vapors will be expelled through the exhaust duct and not through the oven door, blower shaft seal or apertures.
