Compressed Air Best Practices - November 2008 - (Page 27) Compressed Air Industry STEEL & METALS | 11–12/08 | Energy Calculator By choosing an efficient compressed air system the potential savings that can be achieved on a machine can reach up to 60%. Traditional piping systems, made of steel or copper and that are still in use, are known not to be energy efficient, through loss of power and considerable leakages. Difficult to trace and repair, they can have a huge impact on operating budgets. Therefore, Legris Transair has developed an energy calculator that enables system designers to determine the precise savings to be made by using Transair in comparison to other systems. Thanks to this software, contractors/end users can immediately calculate the potential savings that can be made by opting for a Transair solution. On the basis of compressor related data such as pressure, flow rate, annual hours of operation, the type of dryer and data from the characteristics of the network and the local cost of electricity, the Transair energy efficiency calculator software defines the savings and the duration of return on investment. The return of investment is based on the pressure, power or throughput, the number of annual service hours, the type of dryer, plus data from the network, such as length of the main circuit, the type of open or closed circuit, the pipe material used and the local cost of electricity, including inflation factor. The results speak for themselves and show that Transair is the best performing system and the best long term choice, no matter whether the project is for an extension, the modification of an existing network or a new installation. To make the calculation using the Transair Energy Calculator, you will need: p p p The results will show estimations of: p p p Total annual cost for a traditional network and for Transair Total of money saved for 1 to 10 years using Transair The payback period of the initial investment in Transair products An additional “Financial report” will allow you to export and print a chart with a cost comparison, year after year, in order to give all the data to the decision-maker. The software is user friendly. Financial Report. Conclusion In industry today, we face many challenges including the high cost of energy and foreign competition. Your electricity bill is part of your cost and it is a cost that can be controlled in part by using a high-efficiency compressed air pipe system.
