Chamber furnaces

Chamber furnace with air circulation

Oven temperaturemax 350 °C
Batch weight2.000 kg
Batch size1,200 x 2,000 x 2,000 mm (L x W x H)
HeatingDirect electric heating

The compact chamber furnace can be loaded by forklift as well as by movable furnace grate. The furnace door can be moved and pressed on by electric motor. The chamber furnace forms the core for the following modular expandable equipment:

  • Air quench / air shower
  • Water/polymer quenching
  • Charging equipment
  • Chamber furnace line

Chamber furnace with quenching bath

Oven temperaturesmax. 560 °C
Heating capacity1.200 kg/h
Batch weight1.500 kg
Batch size1,200 x 1,500 x 1,500 mm (L x W x H)
HeatingDirect electric heating

The furnace system is fed via the water quench bath using a forklift truck. The water quenching bath has a hydraulic lowering platform and can be tempered between 40 and 85°C by means of electric heating and tube cooling. The batch is transported from the chamber furnace to the quenching bath by means of a push chain. The conversion time is less than 25s. The furnace system is used for solution annealing of aluminum parts.

Chamber furnace with protective gas generator

Oven temperaturesmax. 750 °C
Heating capacity1.100 kg/h
Batch weight2.000 kg
Batch size2.000 x 2.000 x 2.000 mm (L x B x H)
Heatingdirect electric heating
Furnace atmospherevia exogas generator
CO = 1 - 5 %
H² = 1 - 5 %
O² = max. 5ppm
N² = remainder

The furnace system consists of a gas-tight chamber furnace and an exogas generator. The furnace has an air-to-air tube cooler. The furnace door is opened laterally by an electric motor and can be pressed on pneumatically to make it gas-tight.

Activation furnace

Oven temperaturesmax. 500 °C
Heating capacity250 kg/h
Batch size800 x 700 x 400 mm (L x W x H)
HeatingDirect electric heating
Process gasAmmonia
Process fluidTetrachloroethene
Safety purge gasNitrogen

The activation plant is used to remove the passivating metal oxide layer from stainless steel workpieces. This is necessary in order to be able to carry out a nitriding process and obtain a hard surface. Depending on the shape and size of the workpieces, they are brought into the treatment room in baskets or charging racks.
