These cabinets are equipped with the working systems:

• Salt spray “SAL”
• High Humidity “CON”
• Aeration “AIR”

SAL/CON table top test chambers
The SAL system is strictly separated from CON/AIR by a PLC, so the high humidity test will not be interfered by salt spray under no conditions. Whereas conventional combined cabinets are primarily made for conducting salt spray tests and hence are well insulated. However, high humidity tests requires heat losses thus there is a permanent intensive condensation of the vapour. This goalconflict has been eliminated by our unique design of VLM corrosion test cabinets.
We do not apply immersion heaters but surface heaters mounted below the bottom of the chamber. Compared to conventional full plastic chambers the heat conductivity of the ECTFE-coated bottom of our cabinets is far higher. Hence, the water bath is heated up very evenly compared to our high humidity cabinets.
The second unique feature is the double-shelled roof the table top cabinets are standardized furnished with. This insulates the chamber during the salt spray test . However, when the high humidity system is working ambient air is sucked through the inner space of the roof in order to take the heat from the chamber
away.
The patented CWC-System the table top cabinets are furnished with allows to control the temperature in the upper part of the chamber thus there is constant controlled condensation aof the vapour. Consequently these cabinets offer most reproducible climate conditions for high humidity tests as well as for salt spray tests.
The table top cabinets can also be furnished for conducting Kesternichtests simulating industrial pollution climates with SO2. The CWC-System is also available for chest type HD models provided the stainless steel system has been selected.
The combined cabinets can be upgraded easily only by exchanging the control box into one with a PLC, thus cyclic corrosion tests such as VDA 621-415 can be run automatically.

• SAL/CON 400-S : Capacity 400 L
• SAL/CON 1000-S: Capacity 1000 L

SAL/CON chest models HD
These cabinets are supported by a robust stainless steel frame and therefore offer best predonditions for heavy specimen which can be loaded into the chamber by means of a jack. For that reason the acrylic glass cover can be opened very wide. Opening resp closing is supported by gassprings.
The testsolution reservoirs of 130L or 210 L capacity can be placed on the right hand or left hand side of the cabinets. Cabinets for the reservoirs are available as an option. In case there exists a central testsolution supply the cabinets can be equipped with an automatically working testsolution feeding system comprising a 16 l intermediate reservoir.

• SAL/CON 600-T : Capacity 400 L
• SAL/CON 1000-T: Capacity 1000 L

SAL/CON chest models EC “Economy”
These cabinets are designed for every day use. They are economically priced and thus meet small budgets. However, this does not mean any renunciation of the high quality standards VLM stands for. The walls are made of polypropylene and so is the whole body besides the bottom.
This is made of stainless steel coated with ECTFE a fluorine polymer commonly used in chemical engineering. Therefore the chamber can be heated up quick and evenly as well as the HD chests.
