Midea air‑cooled chiller expertise

Whether you run modular air‑cooled systems, heat recovery configurations, or low‑ambient kits, we service the full stack—controls, power, and refrigeration—so your equipment meets load without costly downtime.

• Advanced diagnostics for controllers, network communication, and sensors
• Compressor, inverter/VFD, and soft‑start troubleshooting
• Fan arrays, pumps, and flow verification
• Refrigerant circuit integrity, superheat/subcooling optimization
• Electrical health: phase balance, grounding, and harmonics checks

We document baseline performance, isolate root causes, implement corrective actions, and validate results against design and season.

Common Midea chiller symptoms we resolve

• Capacity shortfalls during peak afternoon loads
• Nuisance trips, high‑pressure or low‑flow alarms
• Unstable staging, erratic VFD behavior, or board faults
• High energy consumption vs. historical baselines
• Recurring leaks, oil return issues, or temperature swings

Our goal is to stabilize your plant so it performs consistently—and predictably—throughout Orange’s varying coastal and inland conditions.
