Compressed air

Compressed air energy is used in the majority of industries and it is converted into mechanical work through either linear or rotary motion using a piston or a pneumatic motor. Only between 4 and 10% of the electricity consumed is used to compress the air, the rest is mainly lost through the heat that has been produced and to a lesser extent through distribution losses, misuse, treatment, etc. for which energy saving measures can be taken to save up to 25% of the energy consumed.

ENERGY SAVING AND EFFICIENCY MEASURES

– Reduce the leaks in the pipe system   (Saving more than 2%)

The air lost in the pipe systems is lost energy and therefore it is an economic loss that all companies must avoid.

– Reduce the air pressure to the minimum  (Saving 1%)

The pressure that must be supplied to the connected equipment must not be higher than the minimum pressure allowed to run the equipment with greater existing minimum pressure of all the pneumatic devices of the industry.

– Supply the compressor with cold/fresh air

Cold air is denser, therefore when air that is colder than room temperature is supplied to the compressor, its mass flow rate increases and therefore its output increases as well.

– Other energy saving measures

• Use compressors with high efficiency motors and frequency inverters that adjust the speed of the motor to the required pressure.
• Choose the right compressor for the required operation without oversizing.
• Use multistage compressors to improve the air compression stage.
• Use the heat produced in other production processes of the company.
• Improve the air flow in the pipes to stop pressure being lost due to friction.
• Service the equipment properly.
• Avoid any unnecessary use of the equipment.
