Proper heat exchanger unit maintenance is critical for preventing costly downtime in data centers. This comprehensive checklist covers 90% of common failure points, helping technical and procurement teams optimize performance and extend equipment lifespan. Discover key maintenance procedures from Liangdi Energy's experts to ensure your heat exchange systems operate at peak efficiency.

Why Heat Exchanger Maintenance Matters in Data Centers

In the rapidly evolving new energy sector, heat exchanger units serve as the circulatory system for liquid-cooled data centers. A single malfunction can cascade into 12-48 hours of unplanned downtime, costing enterprises an average of $9,000 per minute according to Ponemon Institute research. Shandong Liangdi Energy's field data reveals that 73% of premature failures stem from preventable maintenance oversights – particularly in high-density computing environments where our Rack-Mounted CDU solutions operate.

Quarterly Maintenance Checklist (ASHRAE-Compliant)

• Thermal Performance Verification: Measure ΔT between primary/secondary circuits using infrared thermography. Deviations exceeding 5°C indicate fouling.
• Flow Rate Calibration: Confirm secondary side circulation matches design specs (2.7-6.0m³/h for 30-90kW models) via ultrasonic flow meters.
• Electrochemical Corrosion Inspection: Check SUS30408 stainless steel surfaces for pitting or galvanic corrosion at bimetallic junctions.
• PLC System Diagnostics: Validate Modbus/TCP/IP communication integrity and touch display responsiveness.

Annual Overhaul Procedures

Our engineers recommend these critical annual interventions for heat exchanger units in mission-critical applications:

Case Study: Tier IV Data Center Optimization

A hyperscaler implementing our 60kW heat exchanger units reduced maintenance costs by 40% through predictive analytics. By monitoring secondary side pressure drop trends (maintained at ≥1.2bar) and automating deionized water quality checks, they extended service intervals from 6 to 9 months while improving energy efficiency.

Common Maintenance Missteps to Avoid

1. Overlooking Fluid Chemistry: Deionized water/(CH₂OH)₂ mixtures require monthly conductivity testing (target: ≤5μS/cm).
2. Ignoring Seasonal Load Variations: Adjust primary side temperature settings (35-45°C design range) based on ambient conditions.
3. Improper Torque Application: Plate pack compression bolts must be retightened to manufacturer specs during reassembly.
