GFDM Energy Monitoring Package from Festo
Compressed air is one of the most expensive sources of energy on the plant floor of a modern manufacturing facility. Surprisingly, this is generally not a well-known or accepted fact among manufacturers. However, there are certain steps that can be taken by manufacturers to significantly increase the efficiency and economy of their facilities. If compressed air usage is closely monitored, this could not only result in substantial cost savings but could also reduce machine downtime and improve the life expectancy of the machinery.
Manufacturing of compressed air is expensive; 79% of the manufacturing costs are caused by the cost of electrical energy, while 15% and 6% are the costs for capital investment and maintenance respectively. The US Department of Energy uses 18-30 cents per 1000 cubic feet of compressed air as an economic estimate. An internal survey at Festo revealed that 70% of users of compressed air were not even aware of how air is consumed in their facility. 80% said that they had not implemented air consumption reduction programs. With these statistics, it is clear why air consumption reduction is of prime importance.
