Significant energy savings for workpiece cleaning in machine processing thanks to small turbo compressors

Electrical energy consumption cannot be neglected as part of the cost in production. In the years to come, this trend will escalate affecting nearly all industries.

Saving electricity remains a pressing interest in energy-intensive industrial manufacturing processes. One example of energy saving is the cleaning of machined workpieces by removing chippings and other waste-like cooling lubricants.

Cleaning workpieces from chippings and contamination tends to be done with compressed air from a central compressor (reciprocating compressor, screw compressor, or similar) using a distribution network to provide the required air at the workpiece. An often-overlooked variable is the low efficiency of the compressor in comparison to the compressed air required.

The following concept provides an attractive alternative: a decentralised, small, and efficient turbo compressor that delivers compressed air where it is needed – 100 per cent oil and lubricant free.

Estimated savings are based on a compressed air requirement of 6,000 standard litres per minute (SLPM). A centrally reciprocating compressor that distributes the compressed air over a distribution network requires 18 kW to create the required airflow volume. The decentralised turbo compressor (Turbo Compressor CT-22-12000.GB), with its small form factor can be installed next to the machine, requires only 9 kW for the same airflow volume. The difference per hour in a two-shift environment with 250 working days per annum, using an average electricity price of EUR 0.165 per kWh (Germany), is a staggering EUR 6,000 per year.
