ConstaCon® TR – Condensation Humidity Test Chamber

Chest-Type Humidity Resistance Test Chamber

Liebisch ConstaCon® M-SC test chambers have been developed for condensation humidity tests in accordance with standards such as DIN 50017 and TS EN ISO 6270-2. The cabinet-type device is made entirely of glass-fiber reinforced plastic, except for the glass lid. There are no metal parts such as heating elements inside the test chamber that could be affected by corrosion, ensuring long-term durability for corrosion testing. ConstaCon® M-SC chambers are available in three different volumes—400, 1000, and 2000 liters—depending on sample size and quantity. The front-loading design is ideal for test samples of various sizes and provides excellent access to all areas of the chamber. It also allows for easy monitoring of the test in progress. Optional internal lighting can be added for enhanced visibility. The lids on the 400 and 1000-liter models open sideways, while the 2000-liter model features a gas-spring-supported top-opening lid, enabling easy loading of longer samples.

The specially designed wide heating cells in the ConstaCon® M-SC are located in the side walls, completely thermally insulated, and ensure highly uniform temperature distribution with excellent energy efficiency. These heating cells are fully isolated from the corrosive atmosphere in the chamber, allowing the unit to operate reliably for many years without requiring maintenance. The ConstaCon® SC is equipped with separate outlets for air exhaust and drainage, helping to contain the salt mist within the chamber and preventing damage to surrounding laboratory equipment. A removable filter at the drain prevents clogging due to corrosion residue, ensuring a safe and reliable testing environment.

ConstaCon® K – M-SC is specifically designed for continuous 24/7 operation cycles such as DIN 50017 KK and TS EN ISO 6270-2 – CH. In many facilities, these units have been operating non-stop for years, with daily monitoring and rotation of test samples. The manually operated ConstaCon® K – M-SC can optionally be equipped with a cycle timer for alternative temperature cycles such as DIN 50017 – KTW and TS EN ISO 6270-2 – AT. Although opening the lid after 8 hours of testing, as specified in some standards (DIN 50017 – KFW and TS EN ISO 6270-2 – AHT), can achieve cycle completion, the ventilated ConstaCon® KB M-SC model is better suited for this purpose. The ConstaCon® KB – M-SC enables automatic air ventilation at the end of the programmed cycle, eliminating the need for operator intervention. ConstaCon® M-SC includes a constant water level control system and automatically draws water from a pressurized demineralized water line.

Operating the ConstaCon® M-SC is very straightforward. The chamber temperature is set according to the relevant test standard. For KB models, heating and ventilation times can be programmed weekly. Once the ON switch is activated, the unit automatically fills the chamber base with water to a preset level and then begins heating. Heating will not start if there is insufficient water, ensuring safety. When equipped with the optional data recording system, all test conditions can be documented for traceability and compliance.

The chamber temperature in the ConstaCon® M-SC is regulated via the Liebisch Temperature Controller. The temperature sensor is mobile and should be placed at the center of the chamber. It can be repositioned as needed for large samples. Thanks to precisely calculated PID control parameters for each chamber size, temperature fluctuations remain under ±1°C. While a timer is standard for KB models, it can be optionally added to the K model for stopping the test after a preset duration.

ConstaCon® M-SC is designed to operate reliably for many years with minimal maintenance. However, periodic maintenance is recommended to prevent issues such as limescale or algae buildup due to poor water quality or clogged drains due to lack of regular cleaning. The recommended maintenance cycle is annual but may be extended based on environmental factors and proper operator care. Maintenance is provided locally by Kar Kimya’s service team in Turkey.

Plastic Body

Liebisch® ConstaCon® SC is manufactured entirely from glass-fiber reinforced plastic.
The chamber walls, sensors, sample-carrying structures, and sample holders are all made of plastic, ensuring minimal interaction with the corrosive atmosphere.

Easy Access

The glass lid of the ConstaCon® SC allows easy access to every part of the chamber thanks to its front-loading design. Its ergonomic structure enables the operator to load even heavy samples comfortably, while also allowing visual monitoring of the test chamber during operation.
