Smart Factory & Connected Compressors: What It Means in Practice

Smart Factory, Industry 4.0, networked compressors – these terms are ubiquitous. But for maintenance and production management, the practical question is: What are the concrete benefits – and does it pay off?

The focus here is on networked compressors. They make operating data visible and help to objectify decisions.

Smart Factory: Using data to improve availability

At its core, smart factory means: machines and systems generate data that enables decisions to be made. If you record and analyze pressure, temperature, runtime and maintenance status in real time, you can identify problems early on – before they become catastrophic.

Compressed air is often the invisible factor: it is there, nobody thinks about it until something fails. This is exactly where intelligence comes in. With systematic recording of operating data, you can:

• Recognize failure risks at an early stage and plan maintenance in a targeted manner
• Detect energy wastage due to leaks or incorrect settings
• Continuously monitor compressed air quality
• Increase productivity by minimizing downtime

Why compressed air data is valuable

1. energy – the largest hidden cost factor

Compressed air is one of the relevant electricity consumers in many companies. Small inefficiencies add up to noticeable costs over the year. With real-time data, you can see quickly:

• How often the compressor runs in idle mode – unnecessary cycles consume power
• Whether leaks exist – the pressure drops at night despite standstill
• Whether the setpoint pressure has been selected sensibly – too high a pressure increases the energy requirement

The good news is that you don’t have to ‘digitize everything’ – a few, carefully selected data points are often enough to make the biggest levers visible.

2. availability – the invisible productivity plus

A compressor failure costs not only the repair, but also downtime, loss of material and delivery delays. With monitoring, you can detect symptoms before a failure occurs:

• Temperature rise → Radiator clogged?
• Pressure drop → Leakage present?
• Conspicuous running patterns/load changes → Indication of changed operating conditions (depending on the scope of measurement)

Prevention is more economical than emergency repairs.

3. compressed air quality – identifying risks at an early stage

Oil, water or dirt particles in the compressed air can damage tools and products. Operating data such as temperature, pressure and status messages can be used to identify anomalies that may indicate problems with drying or filtration – however, suitable measuring points are required to make reliable statements about compressed air quality.

Four key performance indicators (KPIs) for practical monitoring

KPI stands for ‘Key Performance Indicator’ – in other words, a key figure that quickly shows you in everyday life whether the control, status and consumption are stable. You don’t need a hundred data points. These four variables cover many typical problems:

1. Pressure (current & setpoint): Shows control stability and potential savings
2. Temperature (after compressor): Indicator for cooler status and dew point compliance
3. Operating hours & load-idle cycles: How often does the compressor switch? → Recognize energy waste
4. Maintenance status: filter age, next service due date – centrally documented

Stages of implementation: from local to control room

Level 1: Local recording (low-tech, high benefit)

Depending on the initial situation, networked compressors can start locally or be integrated into control rooms/mobile devices. Modern SCC compressor with touchscreen control: you go on site and see the pressure, temperature and maintenance status directly on the display. Everything is documented. This is already the first big step. No cloud, no IT complexity, simply direct access.

Stage 2: Connection to control room or mobile devices (with additional solution)

The control system provides relevant operating data (e.g. pressure, temperature, running times, status messages). Depending on the IT environment, this data can be integrated into a control room or visualized on mobile devices. Data output is always available on the control unit; an additional solution or software is required for visualization, alarming and integration, depending on the configuration.

Advantage: Real-time alerting and faster response – without having to go to the machine every time.

Stage 3: Permanent web connection / higher-level control (e.g. Airleader) – or temporary measurement

If you need permanent transparency over several compressors and the entire station behavior, a higher-level control system with a web connection (e.g. Airleader) is often the most sustainable way. For specific issues (e.g. new acquisition, expansion or efficiency analysis), a time-limited data logger measurement over a week or so can also be useful – depending on the region in consultation with your SCC partner (dealer/service partner).

What this means in everyday life is best illustrated in typical production and maintenance situations

Practical use cases: Networked compressors in the smart factory

Case 1: Detect leaks, save energy

Scenario: Medium-sized company, electricity bill grows inconspicuously, reason unknown.

With monitoring: data logger shows: pressure drops at night despite standstill. → Leakage verified. A technician checks everything specifically for leaks and uses ultrasound to locate torn hoses or leaking line interfaces, screw connections, couplings and connections in the compressed air network.

Case 2: Optimizing the print ribbon

Scenario: Compressor runs at 10 bar, all consumers work with it – but is this pressure actually needed in the process?

With live data: You can see that the tools are running stably at 8.5 bar. Pressure reduction leads to less energy consumption – without compromising on quality.

Case 3: From reaction to prevention

Scenario: Compressor fails → production stops → expensive emergency service.

With monitoring: Operating hours and operating status are continuously monitored. Noticeable deviations (e.g. unusually high temperatures, changed running patterns or more frequent load changes) can indicate that something is not running ‘normally’ – even before a regular service interval has been reached. This means that maintenance can be scheduled for a planned production gap rather than having to react in an emergency.

Case 4: New compressor design based on facts

Scenario: You are thinking about a new compressor. How big should it be?

With audit data: A 7-day audit provides base load, peak load and their frequency. Design is safe and economical – no guesswork.

Practical introduction in 4 steps

Note: This is a practical framework. The scope and sequence depend on the system, target (energy/availability/quality) and IT environment.

Step 1: Inventory

• Which compressors are installed? (models, age)
• What data sources already exist?
• Who is the contact person? (maintenance staff, IT, production)
• What is the main problem? (Energy, availability, quality?)

Step 2: Start locally (Quick Wins)

• Using modern SCC control: recording initial parameters
• Identify quick wins (e.g. search for leaks)
• Gain an initial understanding of the system behavior

Step 3: Audit/measurement (depending on objective)

• Book audit with data logger (against reimbursement of costs)
• Measurement over one week during normal production (typical)
• Audit report (audit report) with specific recommendations for action received

Step 4: Implement measures & establish a routine

• Realize quick wins immediately
• Making investment decisions on the basis of data
• Establish continuous monitoring

Checklist: Smart factory readiness for compressed air

1. Does the compressor have a digital control with touchscreen?
2. Can you measure pressure, temperature and runtime?
3. Are there documented maintenance intervals?
4. Do your technicians know how to read monitoring data?
5. Can data be transferred to a control room or mobile devices (optional)?
6. Have you defined which data is most important?
7. Can you create a load profile (currently: no, in future: yes)?
8. Which quick wins (leaks, pressure optimization) can be implemented immediately?

Frequently asked questions (FAQ): Smart Factory & Networked Compressors

Do I need a cloud solution right away?

No. Local control with touchscreen is perfectly adequate to start with. You can scale up later. The focus is on meaningful data.

How much does it cost to make the compressor “smart”?

A lot of basic data is already available via the control system. Depending on the system, an additional solution may be useful for alarms, visualization and control room connection. For selective decisions (e.g. new acquisition/optimization), a temporary measurement (load profile) can be organized via your SCC partner. You will receive a concrete assessment after a brief clarification of the objective, inventory and IT environment.

What data do I really need?

Start: pressure, temperature, operating hours. This already covers many typical problems. Optional: flow rate and runtime cycles.

How do I find leaks with monitoring?

Simple: If the pressure drops at night without production, there is a leak. A data logger records this. The technician uses ultrasonic leak detection to find the exact location.

Can I retrofit an older system?

Often yes. External sensors are possible. Costs depend on the age of the compressor. Ask the SCC advice service.

When is a compressed air audit worthwhile?

If your electricity bill is higher than expected, there is a risk of failure or you are planning a new compressor. An audit provides clarity and certainty.
