Calculators and tools

Run your own numbers first.

Standard engineering models, nothing proprietary. They tell you roughly where your system stands; the sensors and the archive tell you why. Results are estimates, not a measurement.

Energy cost

Energy Cost Calculator

What compressed air adds to your electricity bill.

Annual energy—Annual cost—
Energy = kW × load factor × hours × days. Load factor is the share of full-load power actually drawn over the day.
Leakage

Leakage Loss Calculator

Airflow, energy and cost of leaks — from the load/unload test or from an estimated hole size.

Leak flow—Energy lost per year—Cost per year—
Load/unload: leak flow = capacity × loaded ÷ (loaded + unloaded). Hole size: choked orifice flow at line pressure, discharge coefficient 0.65. A typical plant leaks 20–30% of generated air.
Electrical

kW to Amps Converter

Running current for MCC sizing, cable selection and protection settings.

Full-load current—
Storage

Receiver Size Calculator

Receiver volume to ride through a demand event or to limit compressor cycling.

Receiver volume required—
V = Q × t × Patm ÷ (P1 − P2), free-air basis. Round up to the next standard vessel size.
Units

Units Converter

Pressure, flow and temperature in the units compressed-air people actually use.

Being rebuilt for this site

These six tools are moving over from the previous site and will appear here as they are ported.

Compressed Air Score CardBenchmark your system against best practice from power, hours, pressure and tariff.
Isentropic Efficiency CalculatorIdeal versus actual compression — compressor health and degradation.
Heat RecoveryRecoverable waste heat from compressors for water, space or process heating.
Pressure Profile VisualizerPressure drops from generation to point of use.
Moisture EstimatorMoisture content and pressure dew point from operating conditions.
Dryer & Filter Capacity SimulatorRequired dryer and filter capacity for airflow, pressure and temperature.

The numbers raise a question. The archive usually has the answer.
