Fields of application:
The room pressure regulator type CRP is suitable for room pressure regulation by maintaining a constant room pressure.

Function:
The room pressure regulator model CRP can be used for pressure regulation of laboratories of safety classes S1 and S2 and in clean rooms of purity classes C and D (EG-GMP). Clean rooms or laboratories must be kept at a constant degree of overpressure or underpressure compared with adjacent rooms (e.g. corridor). Depending on the application, this prevents the penetration or emergence of contaminated or polluted air with an excessively high proportion of dust.
The CRP is suitable for the independent compensation of over- or underpressure in the room. The setpoint value input can be analog (0... 10 V DC), or be generated by parameterisation using the SVM 100 service module or optionally via the LON network.
The CRP automatically detects the opening of doors and windows and automatically delays compensation of the required room pressure by a parameterisable time (standard = 10 sec). If, for instance, the door is closed again within this period, control only takes place after the door has been closed. This new control concept from SCHAKO reduces unnecessary control cycles, thus significantly increasing the service life and operating reliability of the equipment.
Parameterisation of setpoint values and actual values is possible via the LON network using standard variables (SNVT). Faults (e.g. room pressure level is not reached, level drops below or exceeds limit values, etc.) are detected and signaled via the LON network.
LON networking offers maximum flexibility and reliability. Link-up to the building controller system (BCS) allows complete air-related control and monitoring of all laboratory rooms and remote maintenance of the LabSystem product range.
