LORA

tube furnace for reducing atmospheres up to 1800 °C

With the "LORA" series, HTM Reetz GmbH offers a very versatile model of tube furnaces.
The essential part of the furnace is the working tube made of sintered aluminum oxide. The molybdenum heating conductor is directly wound on the working tube. The interior of the working tube forms the usable space.
The space around the working tube is the heating conductor chamber which is hermetically enclosed in a steel housing. To protect the heating conductor, this chamber is purged with protective gas.

• Maximum temperature up to 1750 °С, for a short period of time up to 1800 °C;
• Temperature is measured directly at the sample;


• Enables operation in reducing, inert and oxidizing atmospheres;
• High heating rates;
• Low power consumption at highest temperatures;


• Little space required;


• Can be operated in any position;
• Separate control unit.

Options

• Gas-tight working space;
• Furnace version with insertion working tube available for operation in vacuum or for specialist applications;
• Furnace version with a water cooled outside wall available;


• "LORA/i" version which enables an easy and quick replacement of the working tube;


• Multi zone furnace versions;
• Optimized heater winding to achieve a long zone with uniform temperature;


• LORA/i" version which enables an easy and quick replacement of the working tube;
• Gradient furnace version, with gradients of
  10 - 100 K/cm, up to temperatures of 1700 °C;


• Versatile "LORA" accessories.
