Did you know that switching from traditional pressure switches to digital controllers can reduce your compressor’s energy consumption by up to 40%? For facility managers and industrial engineers managing compressed air systems, choosing the right pressure control technology can have a dramatic impact on both operational efficiency and bottom-line costs.
Understanding Pressure Control Basics
Pressure control is the heart of any compressed air system, regulating when compressors turn on and off to maintain desired system pressure. Without proper pressure control, systems can suffer from excessive energy consumption, premature equipment wear, and unstable air pressure that affects production quality.
The primary function of pressure control is to maintain consistent system pressure while minimizing energy consumption. This involves monitoring system pressure and controlling compressor operation to match air demand. System pressure directly affects both energy consumption and compressed air quality – for every 2 PSI increase in system pressure, energy consumption increases by approximately 1%.
