Salt-Water-Freeze-Thaw Test machine
for the tests according to EN 13867-1 "Determination of thermal compatibility - Part 1: Freeze-thaw cycling with de-icing slat immersion" and simmilar.
The change between the freeze-thaw cycles takes place automatically. Thus the test in aqueous solutions can be carried out automatically, whciht previously could only be done manually.
The samples can be stored in a test room with a dimensions of approx. 85 cm x 200 cm x 50 cm. The SWF machine allows to storage the samples alternately in saturated soline solution at -15 °C and in water with the temperature in the range of +5 °C to +60 °C. The change of liquids takes place automatically as well. The sample no longer have to be transported by hand.
The water and the soline solutuion are stored at a pre-set temperature in thermally insulated storage containers.
All components of the machine that come into contact with the soline solution are equipped with the appropriate salt-resistant materials to ensure the longevity of the appliance. The test room is made of plastic. The built-in valves are made of high-quality stainless steel or some are made of titanum.
The machine is equipped with two refrigeration systems. With the exception of an annual inspection, the SWF machine is largely maintenance-free. The annual leak test can be carried out by any certified professional.
The SWF machine is fulli netoworkable and is controlled with a computer using a web browser. The user interface is a web page in a web browser, whcih also allows a graphical representation of the measured values.
