Our protective gas and carburization modules allow you to upgrade our annealing and hardening furnaces into a compact annealing and hardening system as an economical alternative to expensive vacuum systems and protective gas furnaces. We can recommend different systems based on your application. Our professional R & D department will be pleased to test your product samples in order to specify the right heat treatment equipment for you. Annealing Box Our annealing boxes with lid sealing may be used for carburizing, annealing and hardening in neutral atmospheres, powder nitriding or boriding. Your...

SHS 41 This compact system is very suitable for hardening under protective atmosphere and subsequent quenching of the charge under protective gas in oil. Hence, this system can be used for hardening processes that would otherwise require complex furnace systems. In our modern research center we can carry out tests and experiments with different materials to specify the right heat treatment process for you.An annealing box with protective gas port containing the work pieces is charged into the furnace. After fi nishing the heat treatment, the box is extracted out manually and placed onto the quenching...

TSB 30/30 with Exhaust gas collection at crucible rim TS 40/40 TS 20/15 - TS(B) 70/90 Salt-bath furnaces offer remarkably high temperature uniformity and excellent heat transfer to the work piece. Our salt-bath furnaces TS 20/15 TS (B) 70/90 are especially useful for heat-treating of metals in neutral or active salt baths. Processes such as nitriding after Tenifer treatment up to 600 ְC, carburizing up to 950 C, or bright annealing up to 1000 аC can be realized. Maximum temperatures of 750 C or 1000 аC Bath temperature control Electric (TS) all-round heating, gas heating on demand (Model TSB)...

N 81/MA N 21/M N 321/MA These gas tight retort furnaces are particularly suitable for annealing processes requiring a constant defi ned atmosphere in the furnace chamber. The gas tight furnace chamber is made from heat resistant steel. The door is sealed by means of a rubber sealing gasket. The sealing fl ange is water-cooled. As an option, the furnaces are also available with a gas circulation fan in the retort to further improve temperature uniformity. At ambient temperature, you can evacuate the furnace chamber with our optional vacuum pump, which reduces the gas consumption considerably during...

Annealing retort with gas circulation Annealing retort without gas circulation S 100/R - S 1000/RA These pit-type retort furnaces are particularly suitable for annealing of heavy charges or charge baskets handled by crane which require heat treatment under protective gas in a defi ned atmosphere. Just like the models N 21/M etc., these furnaces can be evacuated at ambient temperatures to reduce gas consumption during pre-purging. Alternatively, furnaces S 500/RA and larger are available with interior retort gas circulation to further improve temperature uniformity. S 100/R - S 1000/R Pit-type...
