Centrifugal air compressors are known for reliable longevity, but at some point, end- of- serviceable- life decisions must be made. Your centrifugal compressor has been the lifeblood of the factory for upwards of twenty-five years, or longer, but it is finally showing signs of giving up the ghost. Much like when the aging family automobile continues to rack up increasingly more expensive repair bills, operators of aging centrifugal compressors face the decision to repair or replace the machine when the maintenance costs reach a certain threshold.
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.
In late October 2023, professionals from around the world gathered at the Best Practices 2023 EXPO & Conference at McCormick Place in Chicago, Illinois to source and learn about Sustainable, Safe and Reliable On-Site Utilities Powering Automation including compressed air, blowers, vacuum, pneumatics, motors and cooling water systems.
FS-Elliott and FS-Curtis are a combined force, yet each comes to the table with well-established and highly reliable brands of compressed air products. This means they’re fully prepared to tackle customers' goals individually or by working together seamlessly and all with the backing of Fusheng Industrial and parent company Fusheng Group, a Taiwanese-based corporation with annual sales in excess of $2 billion and 20,000-plus employees.
Kaeser Compressors’ President Frank Mueller held a ribbon cutting ceremony, with local and regional dignitaries attending, and in his address to the gathering said, “This 50% increase in office space, the new Rooftop Café, and the warehouse expansion are all dedicated to the well-being, health and productivity of our employees who continue to fuel our growth.”
When selecting a mixing technology, wastewater treatment plants (WWTPs) and their consultant engineers must consider numerous factors, balancing specific treatment demands with plant priorities and ultimately choosing the technology that best suits their needs and specifications. Compressed gas mixing (CGM) is often the best solution, allowing designers to circumvent many challenges that alternative technologies either create or cannot overcome.
This is a two-part article looking at factors impacting decisions on whether to use air or water-cooled air compressors. It also provides heat recovery guidelines for both situations. Part 2 will provide a review of alternative cooling water system options and their approximate operating costs.
To continue meeting demand for air compressors, Doosan Bobcat invested heavily in U.S. manufacturing facilities including its one-million-square-foot manufacturing operation in Statesville, North Carolina. The $70 million expansion of the facility amplified its operations, where it now employs 930 people in office and factory positions and manufactures its line of portable air compressors from 185 cfm to 1,600 cfm, in addition to other Bobcat products like compact tractors, generators, light towers and mini track loaders. It also assembles and stocks the expanding line of Doosan Bobcat industrial air compressors.
“The AICD enjoyed a record turnout of exhibitors,” said Jeff Brennan, President, AICD. “We’ve added over 20 member companies this year and our membership again has delivered a strong turnout at this year’s event.” Participating distributor members and guests enjoyed a few days of networking events, trade show, speakers, the AICD Golf Tournament and more.
This is a two-part article looking at factors impacting decisions on whether to use air or water-cooled air compressors. It also provides heat recovery guidelines for both situations. Part 1 will provide a brief history on air compressor cooling, a review of cooling water sources and costs, and some cooling cost comparisons between air and water-cooled air compressors.
When Hitachi Industrial Equipment Systems Co., Ltd. (HIES) announced Sullair, Hitachi, and Champion Compressors (Australia) have come together under the umbrella of Hitachi Global Air Power (HGAP), many wondered what it would all mean.
