Industrial Utility Efficiency
When selecting an air compressor for your manufacturing operation, the common choice is the industry-standard rotary screw compressor. Known as the work horse of compressed air machinery, the rotary screw compressor comes in a multitude of sizes and power levels. However, centrifugal compressors have seen some exciting technological progress in recent years and offer a wide range of pressures, flow and turndown. Long known for their longevity and durability, they offer higher efficiency, even qualifying for energy rebate programs offered by local utilities and all, notably, produce Class 0 oil free air.
The use of high performance boosters to raise low pressure air (100 psig) to high pressure air (500-600 psig) for blow molders is very power efficient and offers good operating performance and reliability when well applied.
Compressed air is used in all the company’s plants and is often the single largest energy end use within them. As a result, compressed air energy-saving measures are often replicable across the company and offer significant positive impacts. One area of focus is with compressed air leaks since they are “the best low hanging fruit to focus on and they always keep popping up and waste energy”.
The pulp and paper industry depends on reliable sources of energy, water and compressed air; maintaining cost-effective supplies of these utilities is important to every successful business. Within paper making processes, a clean, oil-free air supply is essential for the reliable operation of pneumatic equipment and a high-quality end product. For one manufacturer in Italy, the selection of an oil-free turbocompressor enabled both operational and maintenance costs to be reduced.
The Association of Independent Compressor Distributors (AICD) held its annual show at the Westin Savannah Harbor Golf Resort & Spa in Savannah, GA in May of 2022. Participating distributor members and guest enjoyed a few days of networking events, trade show, speakers, the AICD Golf Tournament and more.
Today Kaishan USA, operates its global manufacturing and engineering center in Loxley, Alabama. The goal of the company, said compressed air industry veteran and Kaishan USA CEO Keith Schumacher, was to put the right pieces in place from the very beginning.
“To that end, we’ve invested $20 million in our facility and created a team allowing us to develop technologies and manufacture products not only for the Americas, but also for export globally,” Schumacher said.
Centrifugal air compressors efficiently convert energy utilizing a series of stages to compress and cool the air as it continuously flows through the unit. A centrifugal compressor imparts kinetic energy into the airstream by increasing the velocity of the air using a rotating element and then converts this kinetic energy into potential energy in the form of pressure. In between each stage of compression, the air is cooled, and excess moisture is removed to further increase the efficiency and air quality.
In order for a compressed air system to be designed properly, altitude must be taken into consideration. In order to calculate the demand profile, tool air consumption must also be adjusted for altitude.
Conventionally when we talk about oil lubricated screw air compressor maintenance, it is mostly about replacing consumables such as filters and lubricant on time. While these consumables have a defined usable life and have a direct effect on the efficiency and the life of the air compressor itself when not replaced on time, there are a few critical valves in the air compressor that require maintenance as well.
Just as many ambient air issues with regard to the actual equipment operating environment are created by personnel and can be corrected by personnel, inlet air contamination is always created by humans and there is almost always a correction that will either eliminate the issue or mitigate the effect.
Growing awareness of the importance of food grade lubricants for consumer safety and Hazard Analysis and Critical Control Point (HACCP) regulations, as well as increasing consciousness about Kosher and Halal registrations triggered an increasing demand for high performance food grade lubricants.
