Bosch - Model CHP CA 570 NA - Compressed-Air-And-Heat System
Compressed-Air Production Without Electricity: In most companies, the supplies of compressed air, heating energy and process heat represent a large cost factor. Production halls must be heated, and products dried or heated for manufacture. Compressed air is utilised in many ways in modern industries, and accounts for around 10 % of total energy costs. This causes high operational costs, which depend on energy and gas prices as well as political conditions. Conventional systems are thus becoming increasingly uneconomical.
A Cost- and Energy-Efficient Solution
Bosch KWK Systeme has developed the innovative CHP CA 570 NA compressed-air-and-heat system to save on operational costs. It combines an oil-injected screw compressor with a gas engine. To use the energy as efficiently as possible, almost all of the heat produced is transferred to the heating circuit.
Versatile Application Possibilities
Our combined heat, power and compressed air system meets a variety of requirements:
- The compressor output is continuously variable (above 60 %) via engine speed
- Maximum output pressure 8.5 bar
- Feed temperature to heating system: constant 90 °C
Our first compressed-air-and-heat system was installed in an industrial company in 2015. At 90 per cent annual utilisation in the year, a savings of over €50,000 was calculated, the carbon footprint was halved, and after less than 3 years, the investment has paid for itself.
- The compressed-air-and-heat system is worthwhile in many ways:
- Energy costs are reduced
- Overall efficiency increases
- Carbon footprint shrinks
- Independence on political
