High-quality Retort Furnaces for a Wide Range of Applications
Our retort furnaces are ideal for tempering tools and for various annealing processes such as recrystallization annealing, stress relieving, solution annealing, thermal aging, and precipitation hardening. They are also perfectly suited for thermochemical heat treatment processes like gas nitriding and nitrocarburizing, including corrosion-resistant post-treatment (oxidation).
Our systems are available in electric and gas-fired versions. Each retort is custom-built to meet your specific process requirements.

TEMPERATURES
Maximum temperature: 750 °C
HEAT TREATMENT PROCESSES • • Tempering
• Bright annealing / Annealing
• Post-oxidizing
• Nitriding / Nitrocarburizing
• Normalizing
• Pearlizing
• Pre-oxidizing
ADDITIONAL OPTIONS
• SUBZERO: The charge can
be deep-frozen directly after tempering (down to approx. -100°C)
• DIRECT COOLING: The
furnace atmosphere is cooled down as quickly as possible using an additional, separate heat exchanger
• REKU HEAT: The installation of recuperative burners achieves a 20% reduction in heating gas consumption
• NITROMA: Nitriding index control with
hydrogen analysis • DRY: An additional heat exchanger allows the furnace to be operated
without external cooling water • HIGH: Furnace door can be designed as a lifting gate • LINE: Expansion to complete, fully automatic nitrocarburizing lines
