PEC-X1

Recently the importance and benefit of controlling differential pressure between rooms (fine differential pressure control in particular) have been recognized, resulting in an increasing number of diverse applications.
It is now being used for high-precision equipment in a variety of areas from the pharmaceutical industry to infectious disease laboratories, hospitals and clean rooms, as well as for preventing odors at garbage disposal facilities.
With the expansion of applications, the use and installation methods of the room pressure controller (PEC-X) have become more diverse, leading to the following responses:

• Some users wish to install a separate motor (EEP series) to open/close an air conditioning damper and a PEC-X, while others wish to install them together at an air conditioning damper as an integrated unit. We can easily satisfy both requests.
• A communication module for a PEC-X is used when the user prefers to monitor the room pressure control and provide the necessary instructions by transmitting and receiving signals between the PEC-X and the central control board of the air conditioning system.
  (Please note that the communication module is an option.)
• If accurate room differential pressure control between rooms is required even when the door is opened or closed, door opening/closing signals can also be used in that control.
• The requests for the greater speed response of a damper and for more torque can be responded to by changing the type of motor (EEP series).
  (Although it depends on the details of your request, the requests for greater speed response and more torque are special specifications.)
• We can also respond to requests for replacing existing equipment as follows:
  If an existing system has a constant air volume (CAV) valve on the air supply side, no change is required on the air supply side, and what is required is just easy work of connecting a power supply and a room pressure detection tube to the PEC-X.
• The PEC-X constantly controls the differential pressure between two rooms, and therefore can prevent any influence of mutual interference, even when a single air supply/release system is used to control the room pressure of a number of rooms.
• The differential pressure between rooms can be maintained even when the airflow varies at the start of operations or when the PEC-X is operated with reduced airflow during, for example, non-operation.
• The standard differential pressure control between rooms is to control only the exhaust air. Please contact us if you require simultaneous control of both the air supply and exhaust to further improve the accuracy.
