Automotive Corrosion Chamber: Ascott Atmosfar
Fully Automatic Climate Chambers
Atmosfär chambers have been specifically designed for fully automatic testing in accordance with highly demanding laboratory-accelerated corrosion tests which have become increasingly popular in some sectors of the automotive industry.
These tests are cyclic in nature and comprise of exposure under controlled and varying conditions of temperature and humidity, with intermittent spraying of a salt solution directly on to the samples under test, from a high level swaying spray bar.
CCT combines the traditional exposure to salt mist with a variety of other controlled climates, including variable temperature & humidity, to create an accelerated simulation of service life conditions. CCT is very well suited to predicting a products total service life expectancy.
A simple touch-screen user interface can be navigated quickly and smoothly through test menus, real-time run parameters and chamber settings.
Humidity and Temperature can be controlled together in multi-step cycles. 4 specific cycles can be created and combined. They are:
- Neutral Salt Spray (NSS)
- Air Drying (PROHESION)
- Controlled Humidity
- Condensation Humidity (SWAAT)
Two sizes are available: 1300 Litre (45.9 cu ft) or 2600 Litre (91.8 cu ft) internal capacity.
This means that even large parts can be fitted without the need to cut smaller smaples pieces. Test entire bumper and bull bar assemblies easily thanks to the vertically-opening canopy.
- Patented "Mag-Drive®" Oscillating spray bar with magnetically coupled drive system, for compliance with the most demanding automotive test standards.
- Integrated air conditioning unit, to achieve demanding temperature and humidity combinations.
- Psychrometric humidity control module, for more exacting control of humidity, especially at levels around 95% RH.
The psychrometric humidity module allows greater degree of control especially at high levels of humidity above 95%RH, it delivers a mechanism unaffected by frequent cycles of extreme humidity, ensuring lifetime integrity of measurement. It utilises two closely matched temperatures sensors, one with the sensing element exposed (called the ‘dry’ sensor/bulb) and one with the sensing element enclosed in a ‘wet sock’ (called the ‘wet’ sensor/bulb). For anything less than a saturated (100%RH) environment, there will be a small difference in the temperature measured by these two sensors. The ‘wet’ sensor will be at a slightly lower temperature than the ‘dry’ sensor due to evaporation from the wet sock surrounding it passing into the air-stream. This difference is called the depression temperature and can used to very accurately calculate the humidity of the passing air-stream.
