2022 New Design Hydrogen Combustion Vacuum Furnace

  The GWL series range of GWL-ZQLB high-temperature vacuum muffle box type furnaces consists of metallic furnaces made of Silicon carbide rod and Silicon molybdenum rod.

  The GWL range is available in 8 different sizes. The smallest designs with a capacity of 4.5 liters and 30 liters are typically employed by laboratories for research and development. The 420-liter furnaces are predominantly used as pilot manufacturing systems or for large-scale production.

  The metallic furnaces permit the greatest possible purity of inert atmosphere and final vacuum level in the vacuum region (-0.1 Mpa). Upon request, an ultra-high vacuum can be configured. Common gases that are typically used include Nitrogen, Argon, Hydrogen, or mixtures. 

  Application Examples

  The carbon-free atmosphere, metal injection molding (MIM), metallization, sintering


Standard features

  • Vacuum furnaces provide a precisely defined atmosphere with the highest possible purity (6 N or better)

  • Vacuum furnaces offer the best possible vacuum

  • Hydrogen partial pressure operation if requested

  • Precisely controlled vacuum pumping speeds appropriate for powders

  • Data recording for quality management

  • Pressure protection

  • Less atmosphere influence 

  • Hydrogen automatic ignition device (New added)

  • Water Cooling machine

Technical details

  Inside the chamber, heating elements are possibly customized based on customer requirements and positioned at the bottom, left, right, and top sides of the furnace chamber allowing for improved temperature uniformity. For larger volumes, Multi-face heating can maintain excellent temperature uniformity. 

  The heating element's long-term working temperature will change during the different atmospheres, more details please confirm with us before ordering.
