  • pressure controller TSI
The Model 8630-CRC PresSura Clean Room Pressure Controller is designed to measure the actual room pressure differential and maintain a constant pressure differential in clean rooms. It modulates the exhaust dampers or variable frequency drive to maintain the proper pressure differential. The Model 8630-CRC can also control the supply air to a constant volume, ensuring proper ventilation of the clean room.

If the pressure differential is too great, too small, or the wrong direction, the 8630-CRC will activate audible and visual alarms. An adjustable alarm delay avoids nuisance alarms when a door is opened.

The 8630-CRC easily integrates to the building management system using a low alarm relay, an analog output of the measured pressure differential, or digital communications. The 8630-CRC supports the open MODBUS protocol.
