Next generation of DSD-series rotary screw compressors unveiled
The next generation of DSD-series rotary screw compressors is now available for flow rates from 14 to 25 mΒ³/min. Featuring all-new airends with high efficiency Sigma Profile rotors and IE4 motors, they deliver improved specific power of up to nine percent as well as up to six percent greater flow rates than previous models. These […]
Compressed air fail: High discharge pressure
By Ron Marshall for the Compressed Air Challenge An automotive manufacturer was having trouble with itsΒ large centrifugal compressors, which were constantly going into surge condition. This is a damaging condition where the air going through the compressor suddenly stops and starts, shocking the fast spinning rotors in the machines and causing stress on the internal […]
New Mi-T-M diesel air compressor/generator combination unit unveiled
Mi-T-M Corp. hasΒ announced the release of the new diesel 30-gal air compressor/generator combination unit. With the convenience of two machines in one, the new air compressor/generator unit is suitableΒ for industrial applications that require electrical power and air. The new air compressor/generator features a 9.1-hp Kohler KD420 diesel overhead valve engine with electric start and glow […]
How important are storage receivers to my screw compressor?
If you have one or more lubricated screw compressors that run partially loaded in load/unload mode, the size of the storage receiver is quite important to the compressor operating efficiencyβand may affect its lifespan. If your compressors run in modulation mode, the least efficient way to run a screw compressor, the compressor efficiency is likely […]
Compressed air fail: Lack of maintenance
A small wood products company was hesitant at first, but after some prodding they allowed a compressed air auditor to have a look at their compressed air system. Instruments were placed on the single air compressor and a flow meter installed. Pressure loggers measured the compressor discharge and plant pressure. When the data was analyzed, […]
Compressed air fail: Missed compressor adjustment
By Ron Marshall for the Compressed Air Challenge A metal fabrication facility ran two separate systems to feed tools and equipment in two shops on their premises. One compressor ran load/unload, the other was a VSD controlled compressor. The plant maintenance engineer attended a Compressed Air Challenge seminar,Β and as a result, came to realize how […]
New Ingersoll Rand Rotary Screw Air Compressors with Variable Speed Drive
Ingersoll Rand has introduced new models to its revolutionary line of Next Generation R-Series compressors, which incorporate the latest advancements in variable speed drive (VSD) technology to increase air flow output by up to 15 percent, reduce energy costs by up to 35 percent and increase system reliability. With the launch of the RS30n and […]
How do I control multiple compressors, Part 2?
To continue this simple question with a complicated answer, in this blog postΒ we will deal with rotary screw compressors, the most common type of compressor found in industrial sites. If you have small reciprocating compressors,Β go back to Part 1 of this discussion. Controlling multiple rotary screw compressors gets more complicated as the number of system […]
How do I control multiple compressors, Part 1?
This is a simple question with a complicated answer. It depends on the type of compressors you have and what your goals are in terms of energy efficiency and pressure control. This first blog post deals with small reciprocating compressors; as forΒ the control of screw compressors, we will save for part 2. If your system […]
