eRCM Pro™ is the industry standard, commercial software package for modeling reciprocating compressors.

erc pro software

eRCM Pro™ features:

Users specify compressor geometry (frame, cylinder, stage, throw, valving, etc.), operating ranges, gas analyses, and unloading devices. eRCM Pro then calculates and displays unit performance outputs such as powers, flows, pressures, and temperatures.

While unit performance is very important, safety is even more critical. eRCM Pro software models unit safety according to how the OEM of that equipment expects it to be modeled. Since OEM calculation methods and limits vary between OEMs, your specific equipment needs to be modeled according to its manufacturer’s safety requirements.

eRCM Pro also helps end users decide on hardware changes. Over time, typical operating pressures may change at a station. Within seconds, a user can model adding a new fixed-volume clearance pocket to a cylinder to identify if that proposed change provides sufficient unloading to accommodate the new operating pressures.

No compressor performance program is complete without an ability to improve its predictions. eRCM Pro accepts results from analyzer data and then uses this real-world data to tune performance predictions to better accommodate the effects of pulsation, pressure drops, effective clearances, actual valve and parasitic losses, friction losses, and more.

  • One File for All Units at Station
  • Create Generic or OEM-specific Models
  • Create Single Service or Multiple Service Models
  • Uses Advanced Thermodynamics (ProSim™)
  • Loads Older eRCM Models
  • Loads Exports from Ariel, Cooper Machinery Services, Siemens Energy, LeROI, NGSG, Arrow Engine, and more.
  • Fully International Aware (numbers, text, etc.)
  • Supports Wide Array of Units of Measure
  • Professional Reports
  • Dynamic Point Performance and Curves

  • Creates P-V plots, Force Plots, Torque Effort Plots, etc.

  • Supports Side Streams In and Out, Including Gas Mixing
  • Easy Creation of Load Step Sequences
  • Creates Wide Array of Tables and 3D Plots
  • Support for variety of load control devices: Fixed and Variable Clearance Pockets, End Deactivators, Timed-valve Closing Devices, Gas Stepless Devices, and even Variable-stroke Devices
  • Files can be used throughout company, from edge/PLC/Monitoring (MMS Sentinel, Monico eRCM Express) to Gas Control (DNV’s Synergi Gas) to Big Data Analytics (Process Innovation Plugins), and more.
  • And still, eRCM Pro generates the fastest performance and graphs in the industry!
