High humidity test chamber
ISO 6270-2, ISO 6988 VLM GmbH

VLM corrosion test cabinets provide best conditions for the conduction of high humidity tests due to its unique design. The bottom, rear wall and roof are made of stainless steel coated with Halar® (ECTFE), a fluorine polymer used in chemical apparatus engineering. Hence there is a quick transfer of the heat from the heaters below the bottom into the water bath. So the water evaporates and condensates very evenly. The best reproducibility of the climate is achieved by the patented CTD-System
VLM CON cabinets for alternating water condensation tests are equipped with the working system “AIR”. That means that ambient air is introduced into the chamber by a fan. The air is evenly distributed to the chamber by a perforated pipe in order to dry the specimen evenly.

We offer a variety of table top models with a chamber capacity of 300 L and 400 L as well as 1000 L cabinets for conducting of tests requiring:

Condensation atmosphere with constant humidity
