1 Premise. The main Italian, German, Austrian, Swiss and WHO regulations, guidelines and recommendations, aimed at preventing surgical infections contracted in the operating room, refer in particular to the verification of the operation of ventilation systems and the quality of the air to be ensured especially in the areas at greatest risk. Studies indicate for sure that the main risks for the onset of surgical infections contracted in the operating room depend on numerous factors such as: • Surgical technique • Staff behavior Clothing worn Number of people present From the degree of sterility...

The concentrations expressed in the table are cumulative, i.e. they represent all particles greater than or equal to the indicated size. * Such concentrations involve sampling a large volume of air for classification. You can apply the sequential classification procedure. ** For this size, in relation to ISO Class 5, the macroparticle descriptor M can be used.

The NICFA AirFlow H-Series with handling grid and Acotex micro-perforated fabric stands out for its flexibility and innovative conception in the field of laminar flow diffusers for operating rooms The main features that make the NICFA AirFlow H Series ceiling mount unique and highperformance are: • Mixing chamber for low heights (dimensions inside the false ceiling 300mm) in AISI304 stainless steel with the possibility of feeding on all four sides according to needs, favored by the particular shape of the recirculation unit. Inside the mixing chamber is installed the compression grid of the absolute...

The H14 absolute filters 68mm high with aluminum frame are housed in the stainless steel containment grid AISI304 in a horizontal position reducing manual movement and excluding any use of tools, they are distributed over the entire surface of the diffuser covering 92% of it. The sealing of the absolute filters is ensured by the double sealing grid system with double gasket that eliminates any possible leak. The containment grids, through a special command from the NICFA Controller or from an external control, are moved independently by an automatic synchronized system that guarantees the uniform...

• The GreenTech EC external rotor motor exceeds class IE4 efficiency, maintenance-free ball bearings with long-term lubrication, Max power 0.75kW and Max flow rate 1500m3/h. • Variable displacement motors sized to the size of the operating theater are controlled and visualized by the NICFA Controller system to ensure consistent operation as the quantities measured by the NICFA Probes change.

3 Monitoring system Introduction NICFA® monitoring for controlled environments is an essential element in ensuring the proper operation and safety of critical environments, such as the operating room. This advanced system has been designed to maintain optimal environmental parameters and ensure compliance with current regulations (UNI ISO 14644 and UNI 11425) offering and guaranteeing complete and reliable management of environmental conditions. 9 NICFA srl Via Stefano Vincenzo Bred, 32/5 35010 Limena (PD) [email protected]

Main Features of the System Constant monitoring The NICFA® system uses probes integrated into the NICFA AirFlow to carry out continuous monitoring according to the requirements of the UNI ISO14644-2 standard, performance and environmental parameters. This constant monitoring is crucial to maintain the stability of operating conditions. The parameters monitored include: •Hall and Flow Temperature: Temperature is a critical parameter that affects performance and safety. The system ensures that the temperature is kept within the specified limits to ensure a stable and controlled environment. •Humidity:...

Control System The NICFA® control system captures the information collected by the environmental probes and processes it through advanced proprietary software. This software is able to analyze data in real-time and implement automatic corrective actions to keep environmental parameters within specified limits. Corrective actions can directly affect the NICFA AirFlow or the AHU (Air Handling Unit) machine, ensuring precise and responsive dynamic control of the environment. 11 NICFA srl Via Stefano Vincenzo Bred, 32/5 35010 Limena (PD) [email protected]

Touch The operating room touch screen for the management of environmental parameters allows the control and display of temperature, humidity, filter differential pressure, room differential pressure, flow rates, AHU machine states. It offers an intuitive interface to monitor realtime environmental data and view recorded data, with alarms for out-of-specification conditions. 12 NICFA srl Via Stefano Vincenzo Bred, 32/5 35010 Limena (PD) [email protected]

Anomaly Detection Early anomaly detection is a crucial function of the NICFA® system. Any deviation from the pre-established parameters is immediately detected and reported by the graphic interface to the responsible personnel. This allows you to intervene quickly to correct any problems, minimizing the risk of operational interruptions or damage to the controlled environment. In the event of malfunctions or emergency situations, the NICFA® system is designed to generate immediate alerts and alarms. These alerts are transmitted instantly to both onsite personnel through the graphical user interface...

The NICFA® system is designed to integrate seamlessly with the Building Management System (BMS) via native Modbus TCP communication. This allows for a smooth, constant and continuous exchange of information between the monitoring and control system and the BMS (e.g. Siemens and other manufacturers), improving the overall management of the building and ensuring that all anomalies are promptly reported and managed.
