Specific Power: Get more output, use less energy, lower costs

Published:  03 November, 2022

HPC discusses Specific Power: The energy efficiency rating of a compressor is called Specific Power – the lower it is, the more you save in energy and money.

How is Specific Power Calculated?

Specific Power is the ratio of total energy used by the compressor and its compressed air output (at a stated pressure).

The lower the Specific Power, the greater the efficiency, and money savings.

Using this calculation, we can see that HPC’s SM13 Rotary Screw Compressor’s Specific Power is 6.4 KW/m3/min.

                           Energy Used ÷ Compressed Air Output = Specific Power

                                          8.56kW ÷ 1.33m³/min = 6.4 KW/m3/min

Equivalent non-HPC compressors typically have a higher Specific Power, exceeding 7.0 KW/m3/min.

How Does This Save You Money?

The cost saving is calculated by multiplying the Specific Power by the total volume of compressed air, by the cost per kWh:

                                     Specific Power x Total Volume Compressed Air x Cost Per kWh = £

This means that investing in a compressor from HPC saves you money in the long-term.

In fact, HPC saves customers up to £25,000 in electricity costs per year.

HPC KAESER Strategy: “More Air, Less Energy”

HPC compressors are designed to ensure they have the best Specific Power to save customers on energy costs.
