Test chambers are designed to examine various types of materials in many different ways for a wide scope of applications. Chambers may be required to measure corrosion or to test components to destruction. Their primary function is to speed up the processes to simulate time in an environment with certain characteristics.
Finding the long term resistance to corrosion of materials requires the speeding up of corrosion by using certain substances. For example, a salt spray testing chamber would recreate the effects of a harsh offshore environment to evaluate the corrosive properties of supplies, such as, paint coatings and phosphated surfaces. This will simulate the effects of years of exposure to salt spray. By testing in a chamber the variables can be controlled to ensure the measure of corrosion is as accurate as possible. Components are subjected to a corrosive environment without introducing other contaminants into the test area.
Chambers are often designed to test for compliance with standards. When components or surface finishes pass testing, they are considered compliant with corrosion resistance standards such as, MIL-STD-202H, BS EN 60068-2-52 or ASTM-B117.
As the environment in the chamber is designed to corrode metal or similar materials the extract system will also corrode if metal fans and metal ductwork are used. We can offer polypropylene fans suitable for this type of application as they are resistant to corrosion. Our fans are the single inlet centrifugal type complete with a pedestal for floor or wall mounting. We have different materials for our pedestals depending on the setting.
We can also offer fans for other types testing in chambers such as, heat testing and humidity testing. This type of equipment has a wide range for which we can offer different types of fans.
