Description

VLM CCT 1000-FL I +60°C Cyclic Corrosion Testing Chamber

Operating temperature from ambient up to +60°C

Compact front-loading cabinet for corrosion testing developed for conducting advanced automatic cyclic corrosion tests pursuant to major corporate standards in the international automotive industry such as:

DIN EN ISO 11997-1:2006 Cycle B (previously VDA 621-415)
VW PV 1210 (external climate module required

This test cabinet is also suitable for performing standard corrosion tests:

Water condensation DIN EN ISO 6270-2:2005 (CH, AT, AHT), ASTM D2247

Salt spray ISO 9227, IEC 60028-2-11 KA

Customer Benefits

The advanced steel design of the chamber allows for fast temperature and humidity transient times making this test chamber perfectly suitable for accelerated corrosion tests – these result in time and energy savings during the operational lifetime

The patented VLM technology allows the best possible reproducibility of the climate conditions being created in the test chamber regardless of the environmental conditions and geographical location
The test chamber made of steel is more robust and less susceptible to damage compared to the competitive products made of glass-reinforced plastic.

Lower cost of ownership compared to the competitive products where the test chamber is made of glass-reinforced plastic (shorter test periods, better energy efficiency, easier for service and maintenance, longer life cycle, more resistive to mechanical damages)

User friendly, menu guided and intuitive control system based on a versatile controller with colour display in which most common standard corrosion tests are already preconfigured

The following Accessories are included:

 6 rods for supporting test specimen
 2 m exhaust hose Ø 50 mm
 2 m drain water hose Ø 18 mm
 1 female connector for compressed air hose (size no. 5)
 1 bag sodium chloride special quality for corrosion testing, accurate weight 5000 g
 1 set of measuring cylinders for measuring the fall our rate
 1 spare filter for the test solution in the reservoir

Applications

Process Control

 User friendly, menu guided JUMO Imago controller with colour graphic display
 Restricted access for operators to three different operating levels
 Memory storage with the capacity to hold up to 50 test programs with the most common corrosion tests already preconfigured in the factory
 The controller steers the external climate module for the tests which require air conditioning (typically PV 1210)
 A full overview of all digital and analogue inputs/outputs

Operating System Salt Spray (according to ISO 9227)

 Electronically controlled diaphragm pump for accurate flow control of the test solution with automatic monitoring of the presence of the air in the pump system
 Adjustable high-performance acrylic spray nozzle for an optimal generation and distribution of the salt fog
 Transparent humidifier made of heat resistant Borosilicate glass with a replaceable PE air filter
 Safety air pressure valve on the humidifier
 Over-temperature protection of the humidifier
 Air purge function for rapid evacuation of the salt fog out of the chamber
 Accessories: 210 L PE storage reservoir for test solution (level indicator optional)
 Option: Aeration with warm air (WA)
 Option: Nozzle for washing the test chamber after the salt spray test is finished

Operating system High Humidity with Controlled Water Condensation - CWC (according to ISO 6270-2 CH)

 CWC system is the patented VLM technology which regulates the temperature gradient of exactly ΔT=1°C between the bottom and the roof of the test chamber – this is essential for an optimal condensation process in the test chamber at 100% RH regardless of the environmental conditions outside the test chamber
 Flat heaters under the bottom of the chamber and behind sidewalls allow for uniform and rapid heating of the water in the trough
 Temperature stability in the chamber ±0,5°C
 Air fan with adjustable

Operating system Forced Air Drying / Aeration

 Aeration with environmental air (aeration with warm air is optional) during the forced air drying phase
 Adjustable air distribution system inside the test chamber for uniform drying of the test specimens
 Fan with controllable rotation speed
 Option: Air conditioning module for providing standard climate acc. to DIN 50014: ambient air at 23°C ±2°C and 50% ±5% RH
