What is it?

• Control Panel Co-processing Unit

• Calculates Complex Compressor Performance

• Performance based on exact and/or comparable Compressor OEM Approaches – because Warranty is based on OEM Methods!

• Uses ModBus Communications

• Predicts safety issues before the compressor goes there – not after it has been there!

Where does it go?

Controls Compressor’s Speed and Unloading

Devices

ControlsPressureValves

Controls Engine Fuel, Timing, Safety, etc.

Requests changes to

speed, ask for allowed load, ask for current

load, etc.

What does it Really do?

• Full Compressor Performance Prediction

• Load, Flow, Fuel, etc.

• Rod Loads, Pin Reversals, Crank Forces, etc.

• Safe Start Up Information

• Provides Valid Ranges:

• For Suction Pressure Throttling

• For Speed Adjustments

• Calculations based on OEM Rules for Safely Operating their Compressors

• Provides Safe Next Load Up and Next Unload Down, regardless of complexity of Load Steps

• Provides wide array of data about unit, stages, throws, and cylinder end.

• Review All Load Steps for safety, not just current one.

• Predicts interstage pressures to know if changing load steps is safe.

Why End-users Need It!

• eRCM Express Units Handle:

• 1 to 6 Stages, 1 to 10 Throws, 1 to 12 Cylinders

• Double-acting, Single-acting, and Tandem Cylinders

• Unique OEM-Comparable Approaches are used for OEM-specific models – not via a one standard fits all approach.
