Systems with multiple compressors are designed to use more sophisticated controls to orchestrate compressor operation and air delivery to the system. A multiple compressor control has two types: network controls and system controls. Network Controls These controls use the on-board compressor controls’ microprocessors that are linked together to form a chain of communication that makes … Continue reading The Basics of Multiple Compressor Control →

WHY Process plants consist of hundreds or thousands of control loops all networked together to produce a product to be offered for sale. Each of these control loops is designed to keep some important process variable such as pressure, flow, temperature, level, etc. within a required operating range to ensure the quality of the end … Continue reading How Valve-Based Control Systems Operate →

Air compressor controls are designed to match the delivery of compress air demand by maintaining the compressor discharge pressure within a specified range. This discharge pressure should be set as low as possible to minimize energy use. There are six basic types of air compressor controls:   Start/Stop This control is the simplest one available. … Continue reading Controls for Air Compressors →

There are three types of compressors: rotary scroll, reciprocating and centrifugal (or dynamic). Unlike rotary and reciprocating air compressors, a centrifugal air compressor is a dynamic system. It increases air pressure using impellers (rotating disks) as well as a diffuser to convert velocity energy to pressure energy. It is important to make sure that when … Continue reading The Benefits of a Centrifugal Compressor →

The rotary scroll compressor is another popular type of compressor. It is commonly used in freezers and fridges to pump around the Freon. It can also be used to compress air in factories or workshops. If you have been wondering how this certain type of compressor works, then wonder no more! Read on to know … Continue reading How a Rotary Scroll-Type Compressor Works →

There’s a growing demand for higher-quality compressed air in chemical and process engineering applications. Compressors come in a variety of types and sizes. Just like everything else, both oil-lubricated and oil-free compressors have their own advantages and disadvantages. For this article, let’s focus on the advantages of a lubricant-free compressor.   Quality Air When it … Continue reading Advantages of a Lubricant-Free Compressor →
