Class A Batch Ovens |
Blue M Class A Batch Ovens are mechanical convection electric chambers that include safety features recommended in NFPA Bulletin 86 as standard.
The design of the 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.
In addition to meeting NFPA recommendations, this oven design has exceptional exhaust capabilities for handling solvents. A negative pressure is maintained in the work chamber that ensures that all hazardous vapors will be expelled through the exhaust duct and not through the oven door, blower shaft seal or other apertures. These ovens are complete systems. No additions are required to meet the recommendations of NFPA Bulletin 86 for processing hazardous work loads.

The industrial batch oven design has exceptional exhaust capabilities for handling solvents. The design of the chamber concedes that the element temperature may be greater than the auto-ignition point of some flammable materials, but a high exhaust rate mitigates the auto-mitigation risk by maintaining a non-explosive mixture. A negative pressure is maintained in the work chamber that ensures that all hazardous vapors will be expelled through the exhaust duct and not through the oven door, blower shaft seal or other apertures.
These ovens are complete systems. No additions are required to meet the recommendations of NFPA Bulletin 86 for processing hazardous work loads.
These Class A industrial batch ovens have Pro-Tronix I solid-state digital indicating control with time proportioning zero crossover performance. Setting and indication accuracy is 1/2%. Large LED display indicates both setpoint and actual chamber temperature at the touch of a button. Separate F.M. approved indicating type instrument provides over-temperature protection.
