Energy efficient compressed air solutions

Avelair 15-37kw compressors

Improving compressed air efficiency for an engineering company in Essex

Overview

Client: Engineering company
Location: Essex
Industry: Engineering and manufacturing
Solution: Compressed air energy audit, leak reduction, pressure optimisation and upgrade to Avelair variable speed air compressors

An established engineering company in Essex approached Avelair to reduce rising energy costs and improve the reliability of its ageing compressed air system. Following a detailed on-site assessment and performance logging, Avelair delivered a clear strategy to increase efficiency, reduce waste and future-proof operations.

The challenge

The company was operating with 10-year-old fixed speed air compressors that were:

  • Consuming excessive electricity
  • Running at unnecessarily high system pressure
  • Suffering from increasing breakdowns and repair costs
  • Causing uncertainty around long-term maintenance budgets

Compressed air is widely regarded as the fourth utility. In engineering environments, it is critical to daily operations. However, inefficient systems can quietly erode profitability through wasted energy and air leaks.

The business required measurable improvements, cost certainty and expert guidance on compliance and system performance.

The solution – Data-led optimisation and modern VSD technology

Step 1 – System monitoring and analysis

Avelair installed energy monitoring equipment to log pressure and air demand over a full week. The detailed report identified:

  • Significant air leaks within the pipework
  • Excessive system pressure
  • Inefficient compressor operation

This data-driven approach ensured all recommendations were evidence-based and financially justified.

Step 2 – Efficiency improvements

Following analysis, Avelair implemented:

  • Targeted air leak reduction
  • System pressure optimisation
  • Upgrade from fixed speed units to new Variable Speed Drive (VSD) air compressors

The new Avelair compressors, manufactured in Bury St Edmunds, Suffolk, were supplied with a comprehensive five-year warranty. This provided the client with predictable servicing costs and eliminated the risk of unexpected repair bills.

The results

Reduced energy consumption

The introduction of VSD air compressors allows motor speed to adjust to real-time air demand, significantly reducing electricity usage.

Lower operating costs

Leak reduction and pressure optimisation immediately improved system efficiency, cutting wasted energy and lowering overall running costs.

Increased reliability

Replacing ageing equipment reduced breakdown risk and improved operational continuity.

Budget certainty

The five-year compressor warranty (and eight-year airend warranty) provided confidence and accurate financial forecasting for maintenance.

Ongoing compressed air support in Essex and East Anglia

Beyond installation, Avelair provides comprehensive compressed air system support across Essex and East Anglia, including:

  • Energy efficiency consultancy
  • Leak detection and system design optimisation
  • Guidance on compliance with Pressure Systems Safety Regulations 2000
  • Advice on air quality requirements for engineering, food and breathing air applications

As a long-standing member of the British Compressed Air Society, Avelair operates in line with industry best practice, ensuring every compressed air system is safe, compliant and efficient.
