How Energy-Efficient is Your Air Compressor System?

Black Air CompressorProfessionals in industrial pipework recommend using high-quality pipes for industrial purposes and certified process control hardware to ensure energy and operational efficiency of pneumatic-based systems. If you carefully study your process facility’s energy usage, you will notice nearly 10% of the total power consumption goes into running these air compressors.

The big question, however, is: When was the last time you monitored the performance of your air compressors, especially for energy efficiency?

Never? Well, that’s bad.

If you want to optimise the amount of energy you spend on running compressors, it is time to take a closer look at their performance. Here are a few helpful tips.

1. Assessing the cooling system for a more economical solution

If your processing facility is in a tropical region and is already placing a high demand on your air-cooling system, it is advisable you switch to water-cooled compressors. In such areas (also during the hot seasons), water-cooling systems are more energy efficient than air-cooling systems.

2. If you insist on the air-cooling option, consider using cold air intake instead

Power consumption in air compressors changes with a change in the temperature of air intake to the compressors. Statistics have it that you can reduce the amount of energy that goes into running compressors by 1% only by lowering air pressure by 2 psi, which reduces air intake temperature by 13.78°C (about 7.2°F).

3. Reviewing compression pressure

Typically, the pressure requirement for most processing facilities is below 60 psi, while an average air compressor can deliver 100 psi. Using these figures, you will realise matching the rated pressure of your air compressing system with your process facility’s air pressure requirements will help save on the energy that goes into producing the extra pressure.

These options are just among many other changes you can effect into your processing facility to, especially, optimise your air compressors’ energy efficiency. In addition, do not ignore the fact that using quality hoses, industrial pipes, drain cocks, and other air tools can also add to the performance of your air compressors.
