Chamber volume
Customised

In the medical industry, an oil filling oven (sometimes called an oil-heated drying oven or thermal processing oven) is used for heat treatment, drying, sterilisation or curing, with oil as the heat-transfer medium instead of air or electric heaters.

Advantages

  • Uniform temperature distribution: oil as a medium reduces hot spots.
  • High temperature stability: ideal for processes that need tight temperature tolerances.
  • Energy efficient: better thermal transfer than air ovens.
  • Non-contaminating: closed-loop systems avoid exposure to fumes or particles.

Hydrogen Furnace (ATF)

Hydrogen Furnace (ATF)

Max. temperature
Up to 2,700 °C
Atmospheres
Wet or dry H₂, inert gas, vacuum
Hot zone
Round or square

Basai hydrogen furnaces, also known as our ATF Series (Advanced Technology Furnace), are designed for high-temperature processing of materials in wet or dry hydrogen, fully dissociated dry ammonia, inert gases or vacuum, and meet the highest safety standards in the industry. Full refractory-metal hot zones and radiation shields give a clean processing environment and the highest vacuum performance.

Rapid heating and cooling enable high throughput for economical processing of high-end products. All systems have side heating elements, with optional top and bottom trim heaters for excellent temperature uniformity throughout the hot zone.

The configuration is tailored to the application, vertical or horizontal, with front, top or bottom loading. The most common is a bell-jar style, where the material stays stationary while the chamber is raised for access. High vacuum, ultra-high vacuum, wet or dry hydrogen and rapid cooling options are easily accommodated.

Standard design features

  • Round or square hot zones.
  • All stainless steel chambers.
  • Stainless steel gas plumbing.
  • Fully automatic operation.
  • Automatic data logging.
  • High-quality refractory metals.
  • Rapid vacuum pump-down.
  • PLC and touchscreen HMIs.
  • Over-temperature control.
  • Monitored water circuits.
