Inert-gas Retort Furnaces Retort furnaces are suitable for heat treatment processes that must becarried out under a defined atmosphere, such as bright annealing, tem-pering or soldering. The product program includes chamber furnaces aswell as pit-type furnaces. Retort furnaces are electrically or gas heated Retort Chamber Furnaces KM 25/11/R – KM 250/11/RT max 1100 °CGas-tight retort furnaces in rugged design with horizontally inserted retortRetort made of highly heat-resistant steelHeating from several sides (both sides and bottom), thus providing uniform temperature distribution in the retortDoor with water-cooled flangeSuitable for various inert gases, e.g. nitrogen, argon, forming gas 95/5Very low gas consumptionOptions:Retort with gas circulation (T max 900 °C)Automatic gassing systemVacuum pump for cold evacuation of the retortProcess control by means of thermocouple in retortCooling fan with exhaust flap control for fast cooling of retort
