Low Pressure System with Short Payback

It is common practice to compress the air up to 8 bar(g) or more, even when the required pressure is much lower, for instance 3,5 bar(g) which is less than half of the initial pressure. In such frequent cases, a considerable amount of energy gets lost. In order to optimize the efficiency, the low pressure compressed air could be generated separately using dedicated low pressure compressors. Indeed, it is more efficient to compress the air at the exact required pressure while pressure reducers are appropriate only for little pressure differences or fractions of one bar. Pneumofore promotes the idea of low pressure loop in compressed air systems for the consistent savings achievable with this solution. The cost for the additional low pressure pipeline is normally paid off within few months. It is part of the Pneumofore offer to calculate the dimensions of the compressed air system at no cost for the customer, in order to guarantee electrical power savings in the long term. Operating from 2,5 to 10 bar(g) with a power range from 10 to 630 kW, the A Series air compressors represent a stable and economical solution for low pressure supply.
