01
Real plants change
Gas composition, suction pressure and suction temperature often differ from datasheet or shop test reference conditions.
Centrifugal compressor performance software
Predict compressor performance beyond design conditions
CMap is a specialized engineering software developed by IPC to predict, analyze and monitor centrifugal compressor performance under real operating conditions, including changes in suction pressure, temperature and gas composition.
Off-design prediction
Transform OEM reference maps into expected performance maps at actual or forecasted inlet conditions.
Measured vs expected
Compare field data with the correct reference and quantify deviations objectively.
Diagnostics and decisions
Support maintenance, RCA, optimization and advanced monitoring with engineering-grade calculations.
Why CMap
Same machine. Different conditions. Different performance.
Compressor performance maps are linked to inlet gas conditions. When plant conditions change, direct comparison with design maps can lead to misleading conclusions.
02
Direct comparison is not valid
Measured performance must not be compared against maps calculated for different inlet conditions.
03
CMap aligns the reference
CMap transforms reference performance maps to the same operating conditions as the field measurement.
Transformation concept
From OEM maps to real operating conditions
CMap bridges the gap between OEM datasheet or shop-test performance and the compressor behavior expected in actual plant operation.
- Reference performance maps from OEM or shop test data
- Gas mixture, inlet pressure and inlet temperature definition
- Thermodynamic and aero-mechanical prediction
- New maps calculated for actual or forecasted operating conditions
Design → Off-design
Performance maps are recalculated at the same inlet conditions used for field measurements or forecasted scenarios.
Reference conditions
Start from a reliable compressor reference
CMap uses reference performance data, typically provided by the OEM or measured during a shop performance test, to build a compressor model that captures the character of the machine.

Calculate the expected behavior at the conditions that matter
Once the new gas composition, suction pressure and suction temperature are defined, CMap calculates the expected compressor maps for those conditions.
