The Weirich HC3 Water Heater/Cooler revolutionizes temperature control in the operating room. No contamination risk thanks to single-use set system, no heat emission, no noise. Two independent water circuits ensure precise control. Intuitive touchscreen operation and quick readiness optimize the OR workflow.

Maximum Safety Without Contamination Risk
The Weirich HC3 Water Heater/Cooler sets new standards in patient safety. Thanks to its closed water system, disinfection and descaling measures are unnecessary. Disposable tanks and pre-connected tubing sets completely eliminate the risk of germ transmission. This protects not only patients but also the operating room staff, who have no contact with chemical cleaning agents.
Efficient Temperature Control
With two independently controllable water circuits, the HC3 ensures precise temperature regulation. The powerful 3-roller pumps enable continuous adjustment of the volume flow from 1–15 l/min. This allows individual control of the temperature of cardioplegia and oxygenator heat exchangers. This ensures stable extracorporeal circulation and contributes to successful surgical procedures.

No Noise, No Heat
Unlike conventional systems, the HC3 operates without a refrigeration unit. This means: no heat emission to the environment and no disruptive fan noise. The silent operation improves the concentration of the surgical team and creates a more pleasant working atmosphere. Thus, the focus remains on what is essential – precise and safe patient care.
Rapid Deployment
Thanks to the innovative disposable set system, the HC3 is ready for use in the shortest time. Filling with filtered drinking water & ice is quick and uncomplicated. After the operation, tanks and tubes are simply removed and disposed of – elaborate deep cleaning is eliminated. This saves valuable time in the OR process and significantly reduces maintenance effort.
Intuitive Operation
The user-friendly touchscreen of the HC3 enables simple control of all functions. The system calibrates itself automatically and venting occurs independently. Refilling the cold water tank is also possible during operation. The smooth-running casters with foot brake allow flexible positioning in the OR – for maximum efficiency in clinical daily routine.
