TSI 8631-CRC-P Room Pressure Controller
The Model 8631-CRC-P PRESSURA Clean Room Pressure Controller is designed to maintain a constant pressure differential in clean rooms. The Model 8631-CRC measures the actual room pressure differential using TSI’s unique bidirectional pressure sensor. It modulates the exhaust dampers or variable frequency drive to maintain the proper pressure differential.
The Model 8631-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 Model 8631-CRC will activate audible and visual alarms. An adjustable alarm delay avoids nuisance alarms when a door is opened. The Model 8631-CRC easily integrates to the building management system, using LonWorks®, an analog output of the measured pressure differential and alarm relays.
