eRCM Express™

Powered by eRCM™ Modeling Software

Empowers UCP with dynamic speed and pressure safety limits
Predicts safe performance across unit’s full operating map
Calculates full rod loads and pin reversals per throw
Simple — just connect the power and Ethernet cables
Provides OEM-compatible modeling
Improves capacity and reduces costs
Models single and multi-stage units

Remove operating map constraints from your reciprocating compressor. Allow it to achieve its full performance.

eRCM Express™ is an industrial computer that powers proven eRCM™ reciprocating compressor modeling technology, conveniently packaged in the robust and field-proven Monico mCore SDR hardware platform.

eRCM Express can be DIN rail mounted, or mounted with angle brackets inside your existing Control Panel.

eRCM Express receives real-time unit operating point data inputs from the PLC. In response, it returns eRCM™ based compressor performance and safety advisor outputs that are critical to safely and efficiently controlling the compressor:

Safety and availability of Next Step Up, Next Step Down, and Ideal Load Step, regardless of complexity of the load step matrix
- Checks for safety issues for all Load Steps, not just current one
Full set of Compressor Performance Predictions:
- Base: Load, Flow, Fuel, etc.
- Safety: Rod Loads, Pin Reversals, Crank Forces, etc.
- Detail: Available data covers unit, all stages, all throws, and all cylinder ends
Provides Safe Start Up Information for setting Load Step before Closing Bypass
Provides dynamic ranges for safely adjusting Suction Pressure during operations
Provides dynamic ranges for safely adjusting Speed during operations
Provides data useful for Condition Monitoring:
- Gas Slippage Rates per cylinder (to know when valves/rings are leaking too much)
- Appropriate Interstage pressures (to know when a serious issue is affecting system)
