Under programmed control, heated immersion liquid (usually salt water heated to a user adjustable temperature up to +50°C/+122°F) is automatically pumped from the holding tank into the chamber, immersing the test samples. The liquid is automatically returned to the holding tank at the end of the immersion period. Immersion is a requirement of standards Hyundai CCT-C, CCT-D, Honda 5100Z & ASTM G44.
AtmosfärPremium test chamber
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.
The Premium version of the Atmosfär Range offers the most extensive and flexible Test Standard scope solution on the market place with increased temperature ranges and faster temperature transition times.
This makes the Atmosfär Premium unique.
CO2 Cooling
Now also available with CO2 Cooling according to EU F-GAS regulation 2024/573
Oscillating spray bar
Oscillating spray bar with magnetically coupled drive system, for compliance with the most demanding automotive test standards.
Smart Control System
7" color touchscreen with intuitive interface. Storage for up to 254 complex test programs.
Remote access via LAN for monitoring and data logging and is compatible with control software S!MPATI from Weiss Technik
Different cooling units from Ambient control
An option of different cooling units from Ambient control (Lite Model) to sub zero at -20 or -40 °C. Water cooled options are also available for sub cooling units where room heat dissipation is an issue.
Psychrometric humidity control
Psychrometric humidity control, for more exacting control of humidity, especially at levels around 94% RH.
Widest application for test norms
The Atmosfar premium range fulfils the widest range of test standards on the market
Vertical airflow
Pre-conditioned air from the separate air conditioning unit, is delivered to the chamber and passes vertically and evenly though the test samples, evenly,- from top to bottom during the climate controlled testing phase
Explore the AtmosfärPremium chamber.
Chamber canopy
The chamber canopy is effortlessly opened/closed using pneumatic cylinders, which are activated at the touch of a button on the control panel. Canopy features a central viewing window to see the samples during test. (Atmosfär Lite only)
Touchscreen Controller
Ergonomically positioned control unit for convenient and intuitive operation. Full-colour touchscreen interface with multi-language function and on-screen graphic of chamber temperatures.
Test Space
Corrosion-resistant test chamber made of Glass Reinforced Plastic (GRP). With easily accessible salt spray atomizer(s).
Dual atomiser salt spray system
Adjustable from ambient to 60°C with a wide fallout range of 0.5 -5.5ml per 80cm² per hour. Required for tests such as VDA 233-102, Renault D17 2028 (ECC1), SAEJ 2334 and RNES-G-0005.
Wall wash spray nozzle
Comprises of a water spray jet nozzles to automatically wash the walls with water for a user adjustable number of minutes, at programmable points within a corrosion test cycle. This test is required for some automotive standards such as Renault D17 2028 (ECC-1). The wall wash assists in generating high humidity whilst driving the temperature down, required by CCT-1 / CCT-2, JASO and many others.
Ultra-rapid ramping heater system
Enables ultra-rapid transition time from 35°C salt spray to 70°C drying within 15 minutes. This is required for Hyundai CCT-A. Also allows for maximum temperature and relative humidity of 80°C and 80% RH to be achieved.
Air Temperature Control Unit (ATCU)
The ATCU is a free standing air temperature and humidity conditioning unit. When required to do so by the program being run, the ATCU will automatically refrigerate air to the required, user adjustable, set temperature. This air is circulated to and from the Atmosfär chamber, by an air circulation fan, via insulated rigid piping. The ATCU requires connection to its own 3 phase electrical power supply. Three versions are available, depending on model ordered.
Communication port
RJ45 communications port for connection to a local area network (LAN) for logging and remote programming via a computer running optional Ascott software (ACC121).
Oscillating spray bar
The swaying spray bar with a magnetically coupled drive system, is set high up in the centre of the chamber, above the test samples. Multiple spray nozzles deliver the salt solution in a fan shaped pattern, to ensure the test samples are ‘swept’ uniformly, directly on to the test samples beneath from a height of over 1M. The spray bar nozzles oscillate backwards and forwards inside the chamber at a user defined speed to optimise pluviometry for specific test standards.
Psychrometric Humidity Control
Psychrometric humidity control module, for more exacting control of humidity, especially at levels around 94% RH.
Salt solution pump and flow meter
During salt spray testing, the peristaltic pump draws salt water into the chamber from the separate salt solution tank, so avoiding the need for a gravity fed system. This salt water is delivered, via a graduated flowmeter, to the salt spray atomiser inside the chamber. The speed of the pump is fully adjustable by the user, to allow the quantity of salt solution atomised and hence the fall-out rate, to be precisely controlled. Two pumps and flowmeters are fitted to 2600L size chambers.
Atmosfär Modes of Operation.
The AtmosfärPremium control system has the widest temperature and humidity envelope in the Ascott chamber range. Not only can the chamber comply with a large number of different less demanding Cyclic and Salt Spray test standard specifications such as, ASTM, Renault’s ECC1, JASO & VDA but can also comply with environmental temperature & humidity testing required by Volkswagen P-VW-1200 & P-VW 1209. Making the AtmosfärPremium chamber truly without equal in the world of corrosion testing.
Our range of standard cyclic chambers come with the ability to create 6 distinct functions to create the most common corrosive environments.
