Best possible protection
of patients and staff

WCD2-c stands for Water Cleaning & Disinfection Device and was developed for cleaning and disinfecting the heating and cooling water of heater-cooler units (hypothermal devices) .


Heating and cooling water from hypothermia devices that are contaminated with bacteria (germs) pose a danger when used in cardiac surgery. For example, when the water hoses are connected and disconnected, water can leak and bacteria can be spread. This increases the risk of infection during heart surgery, especially for patients.


The WCD2-c revolutionizes product safety for patients and staff and is a highly efficient, sustainable alternative to ensure the required drinking water quality of the heating / cooling water.

The new WCD2-c model is available on the market since October 1st, 2023. The WCD2-c is designed exclusively for water purification and disinfection.

Heating/cooling water contaminated with bacteria presents risks at hospitals

Hypothermia devices are used in cardiac surgery to regulate blood temperature during surgery or to warm/cool a patient's entire body.

The risk of infection posed by bacteria-contaminated heating and cooling water in hypothermia devices is not insignificant. It becomes particularly dangerous if this water leaks in a sensitive area (e.g. operating room). Bacteria-contaminated aerosols can pose a high health risk for patients.

Risk of infection for staff

In addition to the patients, the staff is also exposed to a danger that should not be underestimated from the heating and cooling water contaminated with bacteria.

The cleaning and disinfection of hypothermia devices is usually carried out by perfusion technicians. These inevitably come into contact with contaminated heating and cooling water and are therefore always exposed to the risk of illness.

The WCD2-c ensures that the heating and cooling water is of drinking water quality when used regularly. Installation, operation and uninstallation are easy to perform. Wearing protective equipment such as gloves, masks, protective suits, etc. is not necessary.

Quality that creates safety

The WCD2-c not only increases safety for staff, but also makes everyday work easier thanks to its convenient use. The WCD2-c is therefore a sustainable and safe method for water purification/disinfection without chemicals.

Confirmed disinfecting effect

Scientific studies show: The required disinfection performance is clearly achieved with the built-in pro aqua diamond electrode.
