To prevent this damage GLASBAU HAHN offers a range of active climate control systems. All systems operate with a common principle: filters absorb dust and pollutants, continuously “rinsing” the exhibition space with this filtered clean air. Thus, a slight overpressure is created within the display case, and unfiltered air from the outside is unable to enter the case interior.

With GLASBAU HAHN’s new HAHN RK-2-MOL^® CLEAN-Process harmful germs, spores and particularly corrosive vapours like sulphur dioxide within the ambient air are significantly reduced or destroyed prior to entering the display case. This way, material damages caused by airborne pollutants are prevented.

The key technology of the HAHN RK-2-MOL^® CLEAN-Process is a heterogeneous catalytic converter introduced into the water bath of the HAHN RK-2 Unit by means of a wire mesh. Under proper operation it will provide an air purification level fully satisfying conservatory demands. The independent Institute DTE Dr. Tauchnitz Engineering and the certified testing lab Mattersteig & Co Engineers have reviewed and tested the process and its excellent results.

The device has been GS certified.

The HAHN RK-2-MOL^® CLEAN-Process is also introduced to the temperature and Nitrogen modules when a constant relative humidity is desired.

RK-3-N2-F-T*
Nitrogen-/ Relative Humidity and Temperature Module	Prevention of dust and pollutants from entry into the display case with a very dry nitrogen-climate; no corrosion or oxidation. Creation of a desired constant relative humidity and constant temperature environment.
The climate control devices are modular. They can be connected to our software program HAHN CON-TROL which registers the relative humidity and temperature data which can then be checked from remote locations. *All devices are equipped with the HAHN RK-2-MOL® CLEAN-Process.
