Testkamer voor corrosietests SK400C

Deze informatie is helaas alleen in het Engels beschikbaar, maar onze Nederlandse collega’s helpen u graag verder als u vragen in het Nederlands heeft.

With the SK400C corrosive gas test chamber, we have successfully integrated this corrosive gas dosing system into a CTS climatic chamber to ensure standardised climate simulation and thus enable reproducible induction of corrosion.

Its refrigeration technology is designed entirely with CO₂ compressors, making it particularly environmentally friendly and compliant with the latest version of the F-Gas Regulation.

With its outstanding performance and a test volume of 400 litres on up to 3 levels, the SK400C corrosive gas test chamber allows you to efficiently scale up your corrosion tests, making it one of the highest quality corrosive gas test chambers on the market.

Simultaneous dosing of up to 4 corrosive gases

The SK400C is characterised by a removable container made of transparent, corrosion-resistant plastic (PMMA) and can be equipped with up to 4 individual dosing lines. This enables both corrosion testing with individual gases and the simultaneous dosing of up to 4 corrosive gases. The CTS climatic chamber can also be used flexibly for other tests by removing the PMMA container.

Our corrosive gas dosing system can be easily adapted and integrated into different climate chambers of various sizes. Thanks to this adaptability, we can offer you extremely versatile solutions that can be customised precisely to your specific requirements and the conditions of a wide range of test environments.

Highly environmentally friendly refrigeration technology

The refrigeration technology of CTS climate chambers is designed entirely with CO compressors and is therefore particularly environmentally friendly.

Background is the newest version of the F-Gas Regulation, which will ban the commercialisation of “self-contained refrigeration systems” with a GWP value >150 from 2025.

This means that refrigerants used to date (R23, R452a, R449a, etc.) will no longer be allowed. The only non-flammable refrigerant allowed will be CO₂.

The CTS CO₂ solution offers the following features and benefits

  • Cooling with natural refrigerant CO₂ (R744)
  • CO₂ is non-toxic, non-flammable
  • CO₂ is easily and unlimitedly available worldwide and very inexpensive
  • Proven technology
  • No static cooling required
  • Low filling volumes
  • No leak test required for CO₂ refrigerant circuit

Key facts

  • Ideal results thanks to high-precision corrosive gas dosing using a high-quality mass flow controller
  • Ideal injection of the corrosive gases in the carrier gas free jet and homogenization by diffuser expansion before entering the test chamber. As a result, even the smallest concentrations in the range of 10 ppb are homogeneously mixed and brought into the test chamber in the specified concentration.
  • Continuous monitoring of the air exchange rates and gas concentrations by three independent parameters with automatic switch-off when the process parameters are exceeded. These must include the recording and control of the test chamber internal pressure, the carrier air inflow rate, the supply air rate of the corrosive gas dosing and the fan characteristics in relation to the speed
  • Regulation of the air exchange rate by means of a flow sensor at the inlet of the corrosive gas test chamber. This ensures correct concentrations in accordance with the corresponding standard when the corrosive gases enter the test chamber, preventing concentrations from increasing above the standard value.
  • Software specially developed for the application of corrosive gas testing, which guides the user through the individual process steps in a user-friendly manner
  • Clear view of the test material thanks to high-quality acrylic glass windows (polymethyl methacrylate) that enable transparent observation
  • Compliance with industry-leading test standards such as IEC 60068-2-60, IEC 60068-2-42/43 and others to ensure reliable test results

Performance characteristics

  • Possible test gases: hydrogen sulphide (H₂S), sulphur dioxide (SO₂), chlorine gas (Cl₂) with carrier gas N₂, nitrogen dioxide (NO₂) with carrier gas synthetic air, and others
  • Dosing of up to four corrosive gases with 4 corrosive gas dosing lines in the range 1-100 ml/min
  • Pressure monitoring as an integrated safety device for reliable operation
  • Connection for gas sampling for further analysis
  • Testing of the corrosive gas concentration optionally possible with dry air or nitrogen
