Every piece of industrial machinery, no matter how advanced, requires occasional troubleshooting. As the foremost engineering manufacturer in the Netherlands, EVER POWER believes in empowering our clients. This guide covers the most common alarms and operational issues you might face with water-injected compressors, and how to resolve them rapidly.
1. Product Overview: Engineered for Diagnostics
Water-lubricated systems substitute complex oil circuits with advanced water purification loops. When a fault occurs, it is almost always related to water quality, temperature, or air intake restrictions.
- Quick Industry Applicability: Facilities with dedicated maintenance teams like pharmaceutical plants, breweries, and packaging facilities.
- Core Advantages Summary: EVER POWER controllers provide clear, text-based diagnostics (not just cryptic codes), allowing your onsite technicians to isolate issues rapidly without calling expensive OEM support.
2. Technical Parameters (Diagnostic Baselines)
To troubleshoot, you must know what “normal” looks like. Here are the baseline operating metrics for our EP-WI series.
| Parameter | Normal Range | Warning Level (Alarm) | Shutdown Level (Trip) |
|---|---|---|---|
| Discharge Temperature | 35 to 50 degrees C | > 55 degrees C | > 60 degrees C |
| Water Conductivity | < 30 µS/cm | > 50 µS/cm | > 100 µS/cm |
| Water Pressure | 2.0 to 3.5 bar | < 1.5 bar | < 1.0 bar |
3. Working Principle (Why Things Go Wrong)
The system constantly circulates RO water to cool the rotors. If the tap water feed is cut, or if the RO filter gets completely clogged by hard water minerals, the internal water level drops. Without water, the rotors experience friction and the temperature spikes rapidly. The intelligent controller will instantly trip the machine to protect the bronze housing and polymer rotors from catastrophic melting or seizure.
4. Top 5 Troubleshooting Solutions (Card Layout)
🌡️ High Discharge Temp Alarm
Cause: Blocked cooling radiator or low internal water level.
Solution: Clean the external cooling fins with compressed air. Check the main water supply valve and ensure the internal water filter is not blocked.
💧 High Conductivity Alarm
Cause: The RO membrane has failed, allowing minerals in.
Solution: Immediately replace the RO filter element. Continuing to run will cause scale buildup on the rotors.
🌬️ Low Output Pressure
Cause: Intake filter clogged or intake valve failing to open.
Solution: Replace the paper air intake filter. Check the solenoid controlling the intake valve for proper pneumatic pressure.
⚠️ Main Motor Overload
Cause: Severe scale buildup causing rotor friction, or phase imbalance.
Solution: Check incoming voltage across all 3 phases. If electricals are fine, the air-end may require descaling due to poor water maintenance.
💦 Continuous Drain Leaking
Cause: Debris stuck in the automatic drain valve.
Solution: Isolate the compressor, depressurize, and clean the electronic drain valve mesh strainer.
5. Structure and Repairability
Unlike complex dry screw machines that require sending the entire air-end back to a factory for a rebuild, EVER POWER designs for onsite maintainability. The water filter housings use spin-on or quick-release clamps. The bronze housing and stainless steel piping are highly resistant to threading damage during maintenance. The electrical cabinet is cleanly laid out with standardized contactors and VFDs, allowing local electricians to troubleshoot power issues effortlessly.
6. Typical Application Scenarios (Troubleshooting Context)
The environment directly dictates what goes wrong:
- Dusty Warehouses: The most common alarm will be high temperature. Why? Dust clogs the external cooling fins. Regular blow-downs of the radiator are required.
- Cold Environments: If installed near an open loading bay in winter, you might face “sensor fault” alarms if the internal water lines begin to freeze and restrict flow. Always maintain ambient temps above 2 degrees C.
7. Selection & Installation Preventative Guide
The best troubleshooting is prevention. During installation, ensure:
- Proper Ventilation: Ensure there is at least 1.5 meters of clearance around the cooling fan exhaust. If hot air recirculates into the intake, the machine will constantly overheat.
- Dedicated Power Supply: Do not share the compressor’s breaker with heavy welding equipment or massive motors. Voltage drops will cause erratic controller behavior.
- Water Pre-Filtration: If your tap water has sediment, install a cheap $50 pre-filter housing before the water reaches the compressor. This protects the expensive internal RO membranes.

9. Quality Certification & Support
Constructed in accordance with CE and ISO 9001 standards, EVER POWER systems are built for resilience. However, when you do need help, our Netherlands-based engineering team provides remote technical support. Because our software is open, we can guide your onsite electricians via video call, drastically reducing downtime.
10. Global Case Studies (Field Fixes)
📍 Client: Paper Mill in Sweden
Application: General pneumatics.
Feedback: “We had a recurring high-temperature alarm. EVER POWER support guided our tech to check the water pressure regulator. We found a piece of pipe tape blocking it. 10 minutes to clean, zero cost. Brilliant support.”
📍 Client: Brewery in the UK
Application: Fermentation tank aeration.
Feedback: “The conductivity alarm sounded. We ordered standard RO elements locally and swapped them out using the clear manual provided. No need to wait 3 days for an OEM technician. EVER POWER respects its users.”
📍 Client: Plastics Extrusion in Canada
Application: Mold cooling air.
Feedback: “We appreciate the simplicity. When our intake valve stuck due to severe factory dust, the mechanical layout made it incredibly easy to unbolt, clean, and re-install.”

12. Frequently Asked Questions (FAQ)
Q1: If the machine shuts down for high conductivity, can I bypass the sensor to keep production running?
A: We strongly advise against this. Bypassing the sensor allows mineral-heavy water to enter the air-end, which will rapidly calcify and seize the rotors, turning a $100 filter replacement into a total air-end failure.
Q2: Why does water leak from the air receiver tank?
A: Water-injected compressors produce air with 100% relative humidity. If you do not have a functional refrigerated air dryer installed after the compressor, that vapor will condense into liquid water inside your receiver tank and piping.
