Features of the VHP pass box
Features of the VHP pass boxThe VHP pass box is widely used in many fields, not only because of its advanced sterilization principle but also because of a series of practical functional features.The real-time monitoring function is like the "smart eye" of the pass box. With high-precision sensors, it can continuously monitor key parameters such as temperature, humidity, pressure, and hydrogen peroxide concentration inside the inner chamber 24 hours a day. This function is crucial in the sterilization process because an abnormality in any parameter can affect the sterilization effect. For example, temperatures that are too high or too low may alter the chemical activity of hydrogen peroxide, reducing its sterilization capacity; Changes in humidity can cause microorganisms to survive in humid environments, increasing the risk of contamination. Through real-time monitoring, operators can detect these anomalies in time and take appropriate measures to adjust them, ensuring that the sterilization process is always carried out under the best conditions. The light prompt function provides the operator with an intuitive indication of the working status. When the VHP pass box is in different working stages, it will be displayed through different colored lights. In the sterilization stage, a red light may be lit to remind the operator that high-intensity sterilization is being carried out inside the pass box at this time, do not open it at will; During the ventilation phase, blue lights come on to inform the operator that the equipment is being ventilated to remove residual hydrogen peroxide gas. This simple and effective prompt method greatly reduces the risk of misoperation of the operator and improves work efficiency. The application of Siemens PLC's automatic control system provides a solid guarantee for the operation stability and reliability of the VHP transfer window. It is like the "smart brain" of the pass box, which can precisely control the various aspects of the device. From the speed and concentration of hydrogen peroxide gas to the start and stop of the ventilation system, each step is precisely regulated by the PLC automatic control system. It not only ensures that the equipment runs stably according to the preset program but also has a powerful fault diagnosis function. Once the equipment fails, the PLC automatic control system can quickly locate the problem and issue an alarm in time to provide detailed fault information for maintenance personnel, which greatly reduces the downtime of the equipment and improves production efficiency. In addition, some VHP pass boxes have real-time printing capabilities. This function can print out the relevant parameters of each working process, such as sterilization time, hydrogen peroxide concentration change curve, temperature, and humidity data, in the form of paper documents. These printed records not only provide a detailed traceability basis for the production process but also facilitate quality management personnel to carry out quality control and data analysis; At the same time, during the maintenance and maintenance of the equipment, they also provide important reference materials for technical personnel, which helps them better understand the operating status of the equipment, discover potential problems in time and deal with them. |
