Class A Batch Oven

Product details

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.

The Blue M Batch Series Class A Mechanical Convection Ovens are complete systems. No additional equipment or customized procedures are required to meet the recommendations of NFPA 86 for processing hazardous workloads.

Uniform, Accurate and Reliable Temperature Control

  • Available with profiling or single set point temperature controls
  • Horizontal air flow assures uniform thermal performance under most loading conditions
  • Exclusive Blue M Eterna heating elements – the most reliable available, with heavy-gauge high temperature nickel chromium wire and low-watt density for longer service life
  • Direct drive, multi-blade, centrifugal blower with high-volume air delivery and dynamically balanced for noise reduction

Available Oven Options

  • Stainless steel slotted shelves 
  • 24-hour, 7-day digital process timer
  • Temperature recorders (paper or paperless)
  • Programmable controller, Ethernet and USB communications 
  • Data logging and trending 
  • Reverse door hinge 
  • Special truck channel or flat uninsulated floor for customer-designed racks 
  • Stainless steel, roll-in rack 
  • Stainless steel, roll-in rack shelves
  • Variable frequency drive on circulation blower
  • Exclusive, adjustable, semi-pierced duct walls for tuning of airflow
  • Lead-in ports (various locations available)
  • Electro-mechanical or pneumatic door lock
  • Light tower assembly with audible alarm
  • Maintenance lock-out system
  • Main power fused disconnect switch
  • Redundant over-temperature protection (high limit controller) 
  • UL508A labeled control panel 
  • Alternative exterior finishes 
  • CE Mark
