How many compressors do I need for my plant?

Through developing a comprehensive understanding on plant performance, operators can determine how best to meet their compressed air needs. One of the critical questions that must be answered within this process is ‘How many compressors does the plant need’? The answer to this question depends on a range of plant factors. And within this post, we’ll examine this question and help explain how to meet plant capacity through compressed air systems.

Setting the Minimum Ensures Energy Efficiency

It’s important to establish the minimum required number and size of compressors to meet the plant’s energy requirements. This means plant operators must first establish the maximum, minimum and average flow requirements within their facility and applications, and then review the difference between the requirements of certain shifts, as well as the pressure levels within the plant.

Factors that Play a Role in Determining Compressor Capacity

To ensure optimal analysis of their compressor capacity, plant operators must take into consideration a broad array of factors. The system’s altitude, relative humidity and inlet air temperature must all be analysed closely to gain an understanding on compressor capacity requirements. Another element to take into consideration is future compressor demands. For example, equipment might have to go through repairs over the long-term future. This might necessitate the procurement of a rental compressor and therefore operators should consider adding a connection to the primary receiver, as well as a valve to ensure streamlined performance can be achieved should system enhancements or repairs be required.

Consider Mean Air Consumption

The maximum air capacity within any compressed air system should always exceed the maximum air consumption. The functionality of the compressed air receiver plays an important role in managing the consumption process. Receivers should be chosen based on the higher end of the demand scale. And if receivers are unable to handle the difference between the maximum and the average demands for the duration of the peak demand period, compressor capacity must be increased. This means that compressor capacity should be analyzed carefully along with the capacity of the receiver to ensure both pieces equipment have the capacity for optimal compatible performance.

Through careful analysis of their plant’s compressed air demands, as well as a review of the conditions within their plant and applications, plant managers can make effective decisions on the number of compressors their systems require.
