Process system S (salt spray)

Process system K (condensed water)

Process system B (ventilation)

Using a two-component nozzle NaCl test solution is sprayed in the test chamber. Humidified compressed air - using demineralized water - sucks in the test solution from a constant level vessel. The fine salt fog is distributed evenly in the chamber. Parts of the system:

• indirectly heated test chamber with electronical temperature control
• one or more two-component nozzle(s)
• supply tank for test solution
• constant level vessel for test solution supply (alternative: dosing pump)
• humidifier system with automatic water refill

For the condensation water test demineralized water is filled in the bottom of the chamber. The bottom is heated indirectly, the water evaporates. Parts of the system:

• indirectly heated test chamber with electronic temperature control
• system for water refill.                  

The process system “ventilation” is used for ventilating, drying and cooling down of the test chamber and test samples. Ambient air passes through the chamber by a fan. The test room temperature decreases to ambient and the rel. humidity is reduced to ambient conditions. The ventilation system is added to the salt spray / condensation water system. 

Process system W (warm air)

Process system F (humidity)

Process system G (gas)

The warm air system is used for heating and fast drying of the test chamber and samples. It operates only in combination with process system “B” (ventilation). The difference to this system is that the ambient air is heated. The temperature can be controlled up to 60°C. You need this system for special combined tests such as Nissan CCT 1 or ASTM Prohesion.

The process system “F” is used to control the rel. humidity in the test chamber. This system can only operate in combination with the systems ventilation (B) and warm air (W). You can control RH between 30% and 100% for temperature range between ambient and 50°C.

The gas process system is used for automatically dosing a defined volume of pollution gas (Sulphur dioxide). To start the test individual concentrations of gas volume are dosed into the test chamber. This system is available only for KBG 400 / 1000 A-SC.

The systems warm air (W), humidity (F) and gas (G) extend the functions of condensation water and salt spray units. They cannot operate individually!
