Blue M Ultra-Temp Standard Convection Oven

The Blue M Ultra-Temp® Standard, High-Temperature, Industrial Oven is ideal for annealing, heat treating, stress relieving and a number of other high-temperature processes that require temperatures above 350°C.

General Ultra-Temp Oven Specifications

  • Temperature range: 15°C (27°F) above ambient to 704°C (1299°F)
  • Control Accuracy: +/- 1.0°C (+/- 1.8°F)
  • Resolution: +/- 0.1°C (+/- 0.2°F)
  • Workspace capacity: 1.6 to 24.0 cubic feet
  • Uniformity: Blue M can provide varying levels of uniformity; if you have a specific tolerance or specification which must be met, please contact us with your requirements so we can ensure the equipment is designed, tested, and adjusted to meet those requirements

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, adjustable, semi-pierced duct walls for tuning of air flow
  • 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
  • Air flow switch provided as standard to protect oven and product
  • Adjustable one-pass air flow system – tempered air passes over heater(s) and through chamber only once if necessary – readily adjusted to suit a broad range of product loads and operating requirements. Motorized damper available for automatic operation
  • Multi-blade, centrifugal blower with high-volume air delivery and dynamically balanced for minimum noise
