The new microcontroller based MPRCC is a multistage electronic capacity controller for multicylinder reciprocating compressor or rack systems. LCD Based unit has easy to use settings, like Set point -Low pressure (LP), Neutral Zone (NZ), Inter-stage differential (ISD) & Interstage timer. One Analog input ( 4 to 20mA) for pressure transmitter e.g. compressor suction or RTD Pt100 One Digital input (potential free) for Compressor on feedback Four / Six Relay Output for Compressor Capacity Control Solenoid Valves and Compressor trip Adjustable time delay for capacity control solenoid valves Adjustable Neutral Zone, Inter Stage Differential, Calibration Optional RS232 / RS485 port for communication Optional available Software for PC monitoring.
PRCC-04 unit stage control:
Set Point: 2.00 bar
Neutral Zone: 0.15 bar
iner-Stage Differential: 0.10 bar
