Supporting Advanced Manufacturing in Milton Keynes with High-Efficiency Compressed Air

With motor sport pioneers such as Red Bull Racing, precision engineering specialists, and vital suppliers for aerospace, electronics, and food manufacturing, Milton Keynes is one of the UK’s leading centres of advanced industry.

At the heart of all of these operations is a silent, ubiquitous utility: compressed air. It is often taken for granted, but when managed effectively, it is a strategic asset that underpins productivity, quality, and compliance. When it is not, it can be a huge, hidden cost.

In this article, we examine how a systematic approach to compressed air management can address the key challenges faced by all manufacturers in Milton Keynes, transforming an excessive operating cost into a competitive advantage.

The Core Challenges Facing Milton Keynes’ Manufacturers

Companies in Milton Keynes, like those in most cities, operate in an intensely competitive marketplace. Energy costs, driven by unstable gas and electricity prices, are the single most common factor cited by national surveys of manufacturers as an issue faced by UK businesses. Other core challenges include the increasing demands of Industry 4.0 digitalisation, the need for 100% product quality, and the mandatory requirements of regulatory compliance. To ensure these issues are not contributing to any problems, regular review of your core infrastructure is essential, and a good starting point is your compressed air system.

Beyond a Utility: Why Your Compressed Air System is a Strategic Asset

It is a mistake to view compressed air like water or grid electricity. It is the “fourth utility, a manufactured energy source that can account for up to 30% of a facility’s total electricity consumption, and its management is an executive concern:

• For the CFO: An optimised system directly reduces operational expenditure through massive energy savings.
• For the COO: System reliability and predictive maintenance increase uptime and protect production schedules.
• For the CSO: A reduction in energy consumption results in a tangible and reportable decrease in the company’s carbon footprint, supporting its Net Zero goals.

Solving the Energy Crisis: VSD+ Technology and Heat Recovery

High energy bills are the primary pain point for most industrial users, but modern compressed air technology offers a direct solution.

• Variable Speed Drive (VSD): Unlike fixed-speed compressors, Atlas Copco’s VSD and VSD+ compressors precisely match their motor speed to your real-time air demand, ensuring that your system never runs at full power when it doesn’t have to. This simple principle, according to Atlas Copco, can reduce your facility’s energy bills by as much as 60%. VSD systems also reduce mechanical wear by enabling soft starts, avoiding energy-hungry hard starts and extending the lifespan of your equipment.
• Energy Recovery: As much as 94% of the energy used by a compressor is transformed into waste heat, which is usually discarded. Energy recovery units can trap this heat and repurpose it to heat water, either for process use or space heating. One reported case of energy recovery unit use saw a UK manufacturer save £14,554 per year on their energy bills, recouping their capital cost in just one and a half years.

Choosing the Right Compressed Air Technology for Your Application

Selecting the wrong compressor can result in higher energy bills, reduced uptime, or poor air quality. Use the table below to compare critical Atlas Copco technologies by type of application, power range, and special features:

Technology	Typical kW Range	Typical Pressure	Best For	Notable Options
Oil-Injected Screw (GA/GA VSD+)	2 – 250+ kW	7.5, 10, 13 bar	General manufacturing, CNC machining, robotics, and automotive assembly.	VSD, Integrated Dryer, Energy Recovery, SMARTLINK.
Oil-Free Screw (ZT/ZR)	15 – 900 kW	4 – 10 bar	Electronics, food & beverage, pharmaceuticals, and painting/coating.	VSD, Heat-of-Compression Dryer (MD), Water-Cooled.
Oil-Free Scroll (SF)	2 – 22 kW	8 – 10 bar	Laboratories, medical technology, R&D facilities, and point-of-use clean air.	Ultra-low noise, compact footprint.
Oil-Free Centrifugal (ZH)	150+ kW	2 – 10 bar	Significant, stable baseload demand for major manufacturing plants.	High efficiency at full load.

Guaranteeing Quality: The Critical Role of ISO Class 0 Oil-Free Air

For Milton Keynes’ most sensitive industries, air purity is non-negotiable. In the production of electronics, food, or pharmaceuticals, even microscopic oil particles can contaminate entire batches of products. This is a critical consideration for any business utilizing compressed air in the electronics industry.

The global standard for air purity, ISO 8573-1, defines different classes of air quality. The most stringent is Class 0. This certification ensures 100% oil-free air. This means that it is provided by compressors that are designed to have no oil in the compression chamber itself, rather than filtering the air downstream of an oil-lubricated compressor. For businesses where contamination is not an option, Class 0 technology, such as an Atlas Copco ZT or ZR compressor, is the only way to eliminate that risk. Our team can provide a complete air quality testing service to document the purity levels in your system.

Driving Uptime and Digitalisation with SMARTLINK Monitoring

Unplanned downtime can halt production entirely. Modern compressors are intelligent, connected assets that integrate directly into an Industry 4.0 framework. Atlas Copco’s SMARTLINK system provides a turn-key solution, gathering and analysing over 30 data points from your compressor in real-time.

The system alerts you when parameters are outside normal ranges, so you can schedule service before a catastrophic failure occurs. Air compressor monitoring systems, like SMARTLINK, offer data-backed insights to optimise machine availability. In addition to predictive alerts, SMARTLINK’s analytics enable you to comply with standards such as ISO 50001 (energy management) and integrate smoothly with broader IIoT and MES platforms, future-proofing your factory infrastructure.

Ensuring UK Compliance: PSSR, ISO Standards, and Air Quality

Operating a compressed air system in the UK carries legal responsibilities. Anglian Compressors will help ensure your facility is fully compliant and audit-ready.

• PSSR 2000: The Pressure Systems Safety Regulations 2000 mandate that most systems with air receivers must have a Written Scheme of Examination (WSE). This is a legal document defining inspection intervals and procedures, which a competent person must prepare. We provide full support for WSE creation and the subsequent inspections. We also ensure that refrigerant dryers are maintained in accordance with F-Gas regulations. Additionally, we specify systems that meet ISO 1217 (performance testing) and ISO 12500 (filtration testing) standards, supporting audit documentation and quality assurance.

PSSR Compliance Checklist

• Is a current Written Scheme of Examination (WSE) in place for your system?
• Are safety valves and pressure gauges regularly maintained and certified to ensure their proper operation?
• Are the F-Gas service logs for your refrigerant dryers up to date?
• Does an oil/water separator treat oily condensate before discharge?
• Are your required ISO 8573-1 air purity levels documented and regularly tested?
