Blue M 146 Series Inert Gas Mechanical Convection Oven

The Blue M Inert Gas Mechanical Convection Oven, which we pressure-test at
normal operating levels, is ideal for industrial oven applications that involve curing,
heat treating and packaging of electronic components as well as other applications
which require controlled atmosphere environment.

Benefits of the Blue M 146 Series Inert Gas Mechanical Convection Oven

  • High quality design and simple operation
  • Prevents oxidation
  • Impervious barrier between the process chamber and the insulation material
  • Easily maintain inert atmosphere
  • Horizontal air flow assures uniform thermal performance under all loading conditions
  • Differential Air Pressure Switches alert you if loss of pressure or airflow is detected
  • Multiple model options for custom test needs
  • Quick access for simple inner chamber cleaning
  • Easy to use controller

Oven Features

  • All welded and sealed construction assures continuously low oxygen levels
  • Door switch (disables heat and circulation blower upon door opening)
  • Adjustable inert gas purge system including a flowmeter, two-way gas control
    valve, cycle start-up high flow purge, low flow adjustment, chamber pressure
    gauge and supply connection. This feature allows for consistently low oxygen
    PPM levels within the work chamber
  • Adjustable shelf levels
  • Fiberglass insulation to ensure safe cabinet skin temperature
  • Heavy-duty door - double-wall, insulated construction
  • Independent, over-temperature protection (high limit controller) included
  • Corrosion resistant, stainless steel (type 304) interior
  • All-welded, heavy-duty exterior with heavy-gauge, reinforced, cold-rolled steel
  • Baked on white powder-coated enamel finish on exterior for long-lasting
    corrosion protection
  • Every oven is fully assembled and individually factory tested
  • Circuit breaker provided for ground fault protection as standard
  • Single or three phase operation available in 50 Hz or 60 Hz

The following inert gases are approved for these ovens.

  • Argon
  • Carbon Dioxide
  • Helium
  • Nitrogen
