1200°C LGO Element Box Furnaces

The versatile LGO™ Series Box Furnaces feature the latest technical advances in heating elements, insulation and temperature control, all integrated into a self-contained cabinet. The patented LGO heating element (light gauge overbend) delivers maximum radiant heat energy to the process load. The LGO element is embedded within Blue M exclusive Moldatherm® insulation, combined with unique double shell construction to provide optimum temperature uniformity, energy efficiency, fast response, quick heat-up and rapid cool-down.
