Product Features (Atmosphere Sealed Box Furnace)
- Large-capacity furnace chamber, five-sided heating
This box-type atmosphere-sealed box furnace has a furnace chamber size of 1000×1000×800mm (depth×width×height). The heating elements use imported Kanthal resistance wire, evenly distributed around the furnace chamber and at the bottom, forming a five-sided three-dimensional heating field. There are three temperature control points (one on the left and right, one at the front and back, and one at the bottom), with a furnace temperature uniformity of ±5℃ and a temperature control accuracy of ±1℃.
- Electric lifting furnace door, pneumatic locking
The furnace door uses an electric lifting mechanism and is equipped with a pneumatic locking mechanism. A handle switch controls the opening and closing height. The furnace body is completely sealed, making operation convenient and the seal reliable.
- Hot air stirring system, uniform temperature
The top of the furnace chamber is equipped with 310S stainless steel fan blades, which rotate to stir and regulate the temperature inside the furnace chamber. The stirring motor is water-cooled, and its speed is infinitely variable via a frequency converter, with an additional switch for individual control. Effectively eliminates temperature stratification, ensuring uniform temperature distribution within the furnace.
4.2P Chiller with Water-Cooled Sealing Ring Protection
The furnace opening and top sealing areas are CNC machined and feature a water-cooling structure to dissipate heat from the sealing rings, preventing damage due to overheating. The furnace power interface uses vacuum electrodes to ensure a durable seal.
- Vacuum Sealing Structure
The furnace body seal uses high-temperature fluororubber rings, providing excellent overall sealing performance. The furnace body and door are manufactured through polishing, grinding, pickling, phosphating, powder coating, and high-temperature baking, resulting in a novel and attractive appearance with advantages such as oxidation resistance, acid and alkali resistance, corrosion resistance, high-temperature resistance, and easy cleaning.
- 10-inch Touchscreen Control
Equipped with a 10-inch touchscreen, allowing for temperature curve setting and audible and visual alarms upon program completion. Operation is intuitive, and data recording is complete.
- Multi-Intake System
Eight air inlets are evenly distributed across the left and right sides of the furnace chamber. Two flow meters are integrated into one air inlet, and the air intake switch can be controlled by a PLC program to stop and start. The vent is located at the top (DN30) and is adjustable with a valve.
