Measure Before You Replace

Compressed air is one of the most expensive utilities in manufacturing. Yet many systems are upgraded, modified or replaced without first understanding how they actually perform.

At West Midlands Compressors Ltd, we believe decisions should be based on measured system performance rather than assumptions.

That is why we now offer compressed air data logging and performance audits, allowing us to analyse how a system behaves over time and identify hidden inefficiencies.

Using advanced monitoring equipment and cloud-based analysis software, we can measure the key parameters that determine the true efficiency of a compressed air installation.

What Is Compressed Air Data Logging?

Compressed air data logging is the process of monitoring system performance continuously over a period of time, typically between 7 and 14 days.

Specialised sensors are temporarily installed on the compressed air system to measure:

• Air flow demand
• System pressure
• Compressor power consumption
• Load and unload behaviour
• Pressure stability across the network

This data is then analysed to build a detailed profile of how the system operates during production hours, idle periods and shutdown times.

The result is a clear and objective understanding of how efficiently the compressed air system is performing.

Why Data Logging Is Important

Compressed air systems are frequently sized using assumptions rather than real demand.

Over time, production changes, new equipment is added and systems evolve. As a result, compressors may become oversized, inefficient or incorrectly controlled.

Without measurement it is impossible to know:

• How much air is actually being used
• Whether compressors are running efficiently
• How much energy is being wasted
• Whether pressure is higher than necessary
• How significant air leaks are

Data logging provides the evidence needed to optimise the system properly.

What We Measure During A Performance Audit

A typical compressed air performance study will analyse several key parameters.

Air Demand Profile

A flow meter measures the actual compressed air consumption across the monitoring period. This reveals peak demand, average demand and base load requirements.

System Pressure Stability

Pressure loggers monitor how stable the system pressure is and identify pressure drops within the network.

Compressor Energy Consumption

Power monitoring allows us to measure the electrical energy used by compressors and calculate system efficiency.

Compressor Load Behaviour

By analysing compressor loading cycles, we can identify inefficient load/unload operation or poor control strategies.

Leak Load Estimation

Night-time data often reveals the true base load caused by air leaks.

Specific Energy Consumption

By comparing air production and electrical consumption we can determine how efficiently compressed air is being generated.

Typical Problems Data Logging Reveals

Performance audits frequently identify issues such as:

• Oversized compressors
• Excessive system pressure
• Significant air leaks
• Artificial demand caused by high pressure
• Poor compressor control sequencing
• Pressure drops across filters and pipework
• Undersized or poorly designed distribution systems

Many of these problems can lead to substantial energy waste and reduced reliability.

Our Data Logging Process

West Midlands Compressors Ltd follows a structured approach when carrying out a compressed air performance audit.

1. Initial Site Review

We assess the compressor installation and identify suitable locations for monitoring equipment.

2. Installation of Data Loggers

Temporary sensors are installed to monitor air flow, pressure and energy consumption.

3. Monitoring Period

The system is monitored continuously, typically for 7–14 days, to capture real operating conditions.

4. Data Analysis

Performance data is analysed using cloud-based monitoring software to identify trends and inefficiencies.

5. Detailed Performance Report

A structured report is produced summarising findings and recommendations for improvement.

Benefits Of A Compressed Air Performance Audit

A data-driven analysis can help businesses:

• Reduce compressed air energy costs
• Identify hidden air leaks
• Improve compressor reliability
• Optimise system pressure
• Plan equipment upgrades correctly
• Avoid unnecessary compressor replacement

In many cases, significant energy savings can be achieved simply by optimising existing equipment.

Compressed air performance audits are particularly valuable for:

• Manufacturing facilities
• CNC machining workshops
• Laser cutting operations
• Food processing plants
• Automotive suppliers
• Packaging and plastics manufacturers

Any business where compressed air plays a significant role in production can benefit from understanding how their system performs.
