High precision room pressure controller
What is a room pressure controller?
It is mainly used in pharmaceutical factories that are subject to GMP (Good Manufacturing Practice). In 2005, the revised Pharmaceutical Affairs Law made GMP a necessary condition for manufacturing pharmaceuticals. One of the requirements is "prevention of product contamination." To cope with this, it is necessary to manage the differential pressure between rooms (room pressure management) for air conditioning equipment. In addition, pharmaceutical factories are required to undergo "validation*" depending on the product being manufactured. For quality control in the manufacturing process, "room pressure control" is required. Okaya Seiryu Kogyo Co., Ltd.'s "Room Pressure Controller" has been highly rated at sites where differential pressure between rooms is required.
*Validation refers to verifying that a manufacturing facility's equipment, procedures, processes, and quality control methods produce the expected results, and documenting this.
usage environment
- Pharmaceutical factories: sterile preparations, solid preparations, clinical trial laboratories, highly active agents (explosion proof)
- Regenerative medicine (CPC)
- hospital
- semiconductor factory
- Food/processing factories
- Equipment manufacturer (equipment internal pressure control)
Product Features
- Realizes highly accurate and stable differential pressure between rooms
- Unlike the general PID control method, it uses deviation proportional speed control. Since hunting and overshoot can be suppressed, highly accurate control results that are extremely close to the target value can be obtained.
- Reduced time for room pressure adjustment
- Deviation proportional speed control skillfully changes motor speed in response to deviation. Therefore, it has excellent room pressure return performance.
- Easy installation work
- It is self-contained (self-contained) and does not require a control panel.
- Can be used by simply connecting the power line and pressure piping.
- Maintenance is easy because it is self-supporting.
- Communication with the outside world is also possible by incorporating optional functions.
-
- For the motor that operates frequently, use a robust motor with a proven track record for combustion control.
- The control system's ability to maintain the differential pressure between rooms can reduce the frequency of alarms for customers.
- It can be said to be an essential item for pharmaceutical factories both domestically and overseas.
