Innovative concepts for hospitals by Schneider Electric and Flaktwood

The three years of collaborative research by Schneider Electric and Geneva head quartered Fläkt Woods have resulted in the development of intelligent, user-friendly and complete solutions for Operating Theatres in hospitals. One solution, catering to the European market, focuses on smart control of airflows to reduce the infection risk OT and increase productivity and includes:

• DIF-OT operating ceiling with laminar airflow for constant and efficient filtration of air supply to the operating area (ISO4 clean room classification).

• eQ Master Air Handling Units with HEPA filter and Econet energy recovery solution in a closed circuit run around coil system to exclude cross contamination (other configurations possible).

• DEC exhaust air grilles (ISO5 clean room classification) for laminar or turbulent air flows.

• Clean room control panel in the operating theatre including connection to the hospital building management system (BMS) for full control and traceability.

In the collaboration, Schneider Electric has contributed with its expertise within control of critical systems and Fläkt Woods with its advanced air treatment solutions. From a customer perspective, the close collaboration reduces the number of people involved for installation and maintenance, which frees more resources for other customer’s activities.

Today operation theatres are running for around 14 hours a day. This puts high pressure on hygiene and air quality. The solution is developed to match the strictest standards for allowed number of particles /CFU’s (ISO 14644-1) and can be installed quickly. The whole Operating Theatre can be controlled and maintained from a touch screen control panel. Every operation requires specific requirements regarding air flows, temperature, gases, etc. and due to the number of pre-set scenarios the controls of the Operating Theatre is simplified and hence operation lead times. When the Operating Theatre is not in use it is set in stand-by mode to reduce the energy consumption.
