Chamber furnaces
Chamber furnace with air circulation
| Oven temperature | max 350 °C |
| Batch weight | 2.000 kg |
| Batch size | 1,200 x 2,000 x 2,000 mm (L x W x H) |
| Heating | Direct 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 temperatures | max. 560 °C |
| Heating capacity | 1.200 kg/h |
| Batch weight | 1.500 kg |
| Batch size | 1,200 x 1,500 x 1,500 mm (L x W x H) |
| Heating | Direct 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 temperatures | max. 750 °C |
| Heating capacity | 1.100 kg/h |
| Batch weight | 2.000 kg |
| Batch size | 2.000 x 2.000 x 2.000 mm (L x B x H) |
| Heating | direct electric heating |
| Furnace atmosphere | via 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 temperatures | max. 500 °C |
| Heating capacity | 250 kg/h |
| Batch size | 800 x 700 x 400 mm (L x W x H) |
| Heating | Direct electric heating |
| Process gas | Ammonia |
| Process fluid | Tetrachloroethene |
| Safety purge gas | Nitrogen |
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.
