ConstaMatic® SC- Cabinet Type Cyclic Corrosion Test Chamber

Liebisch ConstaMatic® A-SC test chambers are specifically designed for cyclic corrosion tests. The device can be configured according to required standards by integrating systems such as S-K-B-W-D-F-R-C-Frost developed by Liebisch.

Unlike ConstaSal® M-SC and ConstaCon® M-SC, ConstaMatic® A-TR is equipped with a programmable touchscreen PLC control panel. The PLC panel, available in multiple languages including Turkish, allows for detailed programming of cyclic tests and offers excellent documentation options. Set and measured values are recorded over time during the test. Optionally, these records can be transferred to a computer via USB or LAN. If any environmental issue arises—such as low air pressure, insufficient pure water level, or power outage—that may affect the reliability of the test, the device records the error and time, stops the test, and waits for operator intervention. Optionally, the device can notify the operator via email, minimizing downtime and maintaining high test quality.

ConstaMatic® A-SC is a cabinet-type device made entirely of glass-reinforced plastic, excluding its inert glass lid. There are no metal components, heating units, or elements inside the test chamber that could be affected by corrosion, ensuring long-term durability in corrosion tests.

The chambers are available in 3 volumes—400, 1000, and 2000 liters—depending on the size and number of samples to be tested. All models are front-loading, making them ideal for various sample sizes. Front loading provides easy access to every part of the chamber and allows for visual monitoring during tests. Optionally, test chamber lighting can be added for better visibility. The lids open sideways in the 400 and 1000-liter models, while the 2000-liter model features a top-opening lid with gas springs, allowing long samples to be loaded easily.

ConstaMatic® SC features specially designed wide heating zones integrated into the side walls, fully thermally insulated to provide highly homogeneous temperature distribution and excellent energy efficiency. These heating zones are completely isolated from the corrosive test atmosphere, allowing the device to operate reliably for years without requiring service. The system includes two separate outlets—one for air exhaust and one for drainage, which is automatically closed during humidity tests—ensuring salt fog is optimally contained within the chamber and does not damage other lab equipment. A removable filter in the drain prevents clogging from corrosion residues, maintaining a reliable and safe testing environment.

ConstaMatic® A-SC is built for long-term cyclic corrosion tests lasting several weeks. However, many customers also prefer the advanced user interface of the ConstaMatic® A-TR for continuous tests such as salt spray and constant humidity. For companies that schedule periodic salt spray and humidity tests using the same equipment, ConstaMatic® A-SC offers space and cost efficiency. It is a fully automatic corrosion test device, requiring no operator intervention other than routine parameter checks during tests.

The ConstaMatic® A-SC is easy to use, with a multi-language interface including Turkish. Parameters for many standard test norms are pre-loaded into the device, and selecting the desired standard from the menu automatically applies the required settings. The test can be programmed to start or stop at a specified time. Sophisticated, calibratable digital dosing pumps are used in the salt spray and humidity steps of cyclic tests. These pumps provide highly stable dosing and are unaffected by hose stiffness, unlike peristaltic pumps, and they require no monthly maintenance or part replacement by the operator.

Before opening the lid at the end of a test or for sample inspection, the operator can activate the ventilation system to introduce fresh air into the chamber, expelling the corrosive fog through the exhaust. Within minutes, the lid can be safely opened without releasing harmful vapors into the lab, thereby protecting surrounding equipment.

Thanks to individually calculated PID control parameters for each chamber size and test type (salt spray, humidity, or cyclic tests), the temperature fluctuation in both the test chamber and humidification tower remains below ±1°C.

If high-quality air, demineralized water, and salt are provided, ConstaMatic® A-SC can operate for many years without requiring maintenance. However, due to potential algae formation in the solution intake line from pure water or contamination in the humidification tower from air impurities, periodic maintenance is recommended. The maintenance interval is annually but may extend up to two years under favorable environmental conditions. Maintenance is performed by Kar Kimya’s local service team in Turkey.
