Is more kilowatts and more air better?

Like so many industries, the compressed air industry is in full swing. Not least driven by efficiency improvements with regard to energy consumption and therefore indirectly also with climate change. If you are going to buy a new compressor, you will of course pay...

IGV or IBV ? , that is the question…

In the 20th Century inlet butterfly valves (IBV) on centrifugal air compressors were the standard. But as there came more demand for better energy efficiency the application of IGV’s rose. IGV stands for inlet guide vanes, this technology was adopted from the turbine...

What is real oil free air ?

  There are applications in industry that require clean air. And by clean we mean very clean. So the degree of purity.This purity is laid down in an ISO standard. This ISO standard is 8573-1: 2010. It describes 7 classes that indicate how many solid parts (for...

Pressure Dew Point (PDP) Explained in compressed air systems

Pressure Dew Point (PDP) Explained in compressed air systems

The measure of how much water vapor there is in a gas is called dew point temperature. Not to be mixed up with pressure dew point. The term “pressure dew point” is used when measuring the dew point temperature of gases or compressed air at pressures higher than...

Compressed air energy storage (CAES)

Compressed air energy storage (CAES)

Compressed air energy storage  is a method to buffer energy generated at times of overcapacity for use at another time. This means that energy generated during periods of low demand (off-peak) can be utilised to meet high demand (peak load) periods.Traditional...

Avoid high ambient air temperatures and save money !

Avoid high ambient air temperatures and save money !

During the summer period operation costs for compressed air installations rise unnecessarily. Due to high ambient temperatures in the compressor room decreases the efficiency of compressors and dryers dramatically. At the same time the number of technical failures...
