Estimate monthly and annual compressor electricity cost in South African rand.
Enter your operating assumptions and calculate.
The percentage field is an assumption for average electrical demand. Controller data or a power logger provides a better estimate, especially where a fixed-speed compressor spends time unloaded or a VSD compressor follows a variable load.
The formulas are provided as planning aids. Receiver calculations use an ideal-gas storage approximation with atmospheric pressure of 1.01325 bar. Final design must be verified for the selected equipment, control method, pressure rating and application.
