เครื่องทดสอบการเร่งสภาวะแวดล้อมแบบวนรอบ ประกอบด้วย Swaying spray bar salt spray, Salt fog, Wetting, Drying และ Control humidity สามารถรองรับมาตรฐานใหม่ที่แพร่หลายในกลุ่มยานยนต์ในปัจจุบัน เช่น Ford CEPT L-467, Scania, GMW และ Japan CCT-1 , JASO M609.

The AtmosfärLite test chamber has been specifically designed to facilitate fully automatic testing in accordance with highly demanding laboratory-accelerated corrosion tests, which have become increasingly popular,particularly in the automotive industry.

Such tests standard include:

  • Ford CETP 00.00-L-467 / Volvo VCS 1027,149 (ACT-1) / Volvo VCS 1027,1449 (ACT-2) / Volvo STD 423-0014 / Volvo STD 1027,1375 / Scania STD431
  • GMW14872
  • CCT1 & CCT2
  • VDA621-415
  • ISO 16701

Features :

  • Swaying spray bar
    Set high in the chamber, spray nozzles oscillate backwards and forwards to produce a fan shaped spray pattern that ensures test samples are ‘swept’ uniformly with spray of salt solution.

  • Separate air conditioning unit
    Combines refrigeration and dehumidification to extend the range of temperature and humidity control (down to 20°C/68°F under programmable control
  • High velocity vertical air-flow
    High velocity air, from the separate air conditioning unit, passes vertically though the test samples, evenly from top to bottom, during the climate controlled testing phase.

  • MAG-DRIVE™ – magnetically coupled
    Spray bar drive system Enables quick spray bar removal from the chamber if conventional salt spray testing is required. With no drive shaft passing through the chamber wall, there is no risk of salt solution leakage and it is safe as it will stall if the spray nozzles are obstructed.

 

  • Psychrometric Humidity Measurement Module

A mechanism unaffected by frequent cycles of extreme humidity, ensuring lifetime integrity of measurement. Provides a wider operating envelope, with improved performance at humidity levels around 95%RH.

  • For added flexibility, Atmosfär chambers also retain the ability to perform conventional salt spray tests and Cyclic Corrosion Tests (CCT) in accordance with a wide range of international test standards.
