There are two sizes of Atmosfär chamber each offered with various choices of refrigeration system and the choice of air cooled or water cooled sub-zero units, making a ten model line-up in total. They are: 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.

The chamber is a package deal and includes the following accessories as standard:

• 1 x ACC42 – Wall Wash
• 1 x ACC47 – Ultra rapid ramping heater system to 80C
• 1 x ACC121 – Chamber Logging Software
• 1 x ACC10/2 – 110mm Entry Port
• 1 x ACC102 – Salt Solution Consumption Sensor
• 1 x ACC01 – ECC1 Kit
• 1 x ACC25 – Additional atomisers for 0.5 – 5.5ml fallout range
• 1 x ACC82 – Window Plug (ATPremium Lite only)
• 1 x ACC31 – Oscillating Spray Bar
• 1 x ACC03 – Additional Heater mats to reach 60C During salt spray
• 1 x ACC108 – Fallout measuring kit
• 1 x ACC57/2 – 1 Year consumables kit
• 1 x ACC59/13 – 90L Salt Solution Tank
• 1 x ACC59/9 – 160L Salt Solution Tank

Plus one of the following with Psychometric humidity control:

• ATPremium Lite -  ACC112 & ACC112/INT
• ATPremium  - ACC29 & ACC29/INT

• 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.
