Compressed Air Cost for Coating with compressor power for coating of 30 kW: a worked example
This scenario runs the compressed air cost for coating calculation on the strong side: compressor power for coating of 30 kW, with every other input held at its documented default. Use this calculator for practical powder coating or surface finishing planning, quoting, troubleshooting, or line setup.
The inputs for this scenario
- Compressor power for coating: 30 kW (raised for this scenario; the documented default is 12)
- Coating air runtime: 8 hr (unchanged)
- Energy rate: 0.12 $ / kWh (unchanged)
- Parts coated: 1,000 parts (unchanged)
Working through the calculation
- Applying the documented formula (Energy cost = connected load × runtime × energy rate) to the inputs above produces each figure below.
- At this operating point the engine returns 28.8 $ / shift for energy cost, the number this scenario is built around.
- At this operating point the engine returns 240 kWh for energy used.
- At this operating point the engine returns 0.03 $ / piece for cost per piece.
- At this operating point the engine returns 3.6 $ / hr for hourly cost.
How this compares with the baseline
- Against the tool's baseline example, where compressor power for coating sits at 12 kW and the headline result is 11.52 $ / shift, this scenario comes in 150% above the baseline at 28.8 $ / shift.
- Use it when building a per-part cost model or hunting for finishing-line energy savings and leak-reduction ROI. Treat this as a target state: the delta against the baseline quantifies what the improvement is worth before you commit to chasing it.
