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.
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.
This article will be of particular interest to industrial system operators unfamiliar with tankless (primarily closed) systems who may be considering either installing new systems without tanks or removing existing open tanks. The topics covered step through an understanding of tankless systems while also including tank system pointers and insights on converting systems with tanks into tankless systems.
The Cooling Technology Institute’s (CTI) four educational sessions drew standing-room-only crowds. Representatives from BPEARSON Consulting, SPX Cooling Tech, Eurovent and Baltimore Aircoil Company presented Fundamentals of Water Treatment; Cooling Tower Fundamentals; System Sustainability? Prove it with Certified Performance; and Fundamentals of Adiabatic Heat Rejection. Owners and operators of heat rejection equipment can join the CTI and attend its annual conference to meet the several dozens of technical experts with hundreds of years of combined experience capable of assisting with your next project.
With efficient heat exchange an important requirement in the design of an HVAC system, the type of cooling tower you specify to support your project’s unique cooling goals requires careful consideration. After determining the process parameters required for your application – tonnage, range, and approach – cooling tower capabilities can be analyzed.
A large manufacturer of consumer glassware products in the North East sought a solution for injecting cold compressed air into its refractory furnace. Doing so would minimize the internal corrosion thereby extending the life of the furnace lining and their annual maintenance interval. The manufacturer opted for a unique solution from Aggreko Engineering featuring a rental, oil-free rotary screw air compressor combined with a heat exchanger and chiller. Installed in 2019, the solution is expected to save the company \$9 million monthly given the ability to maintain extend furnace maintenance from one year to two years – and boost plant uptime.
The Best Practices EXPO & Conference held from October 13-16, 2019 in Nashville, Tennessee, saw a significant increase in attendance growing by 15 percent to 850 attendees from 20 countries. End user (factory personnel) attendance grew by 60 percent! The EXPO was also truly international showcasing 115 exhibitors from 16 countries and EXPO attendance was free for qualified industry personnel. This SHOW REPORT EXTRA Part 2 complements our 2019 Best Practices EXPO & Conference Show Report and the Show Extra Part 1 Report.
The event brought together technology experts, systems assessment professionals, and manufacturing leaders – all of whom shared best practices and ideas manufacturing plants can use to save energy, improve sustainability initiatives and increase the overall reliability and quality of on-site utilities.
Held September 16-19, 2018 in Chicago, the first-ever event drew 750 attendees who came together to learn and share ideas about the countless ways to achieve efficiencies with compressed air, blower, vacuum and cooling systems – and in the process – save energy and improve profitability.
As a result of compressed air awareness training and a focus on energy management, two facilities in different parts of the world have reduced their compressed air demand substantially by removing vortex style cabinet coolers from some of their electrical panels and reworking the cooling systems. These facilities were previously unaware of the high cost of compressed air and how much could be saved if other methods of cooling were used. This article describes some of their efforts in demand reduction.
As the population continues to grow in the United States, industrial water use will need to continue to fall to help offset the increases in public-supply water use. Water-cooled compressed air systems provide an opportunity for sustainability managers to reduce associated cooling water consumption and costs. If switching to air-cooled air compressors is not possible, understanding the costs and the alternative types of liquid cooling systems is important.
