High Head Pressure Diagnostics: Condenser Scale, Non-Condensables & Fan Speeds
Excessive head pressure is an industrial plant emergency that forces compressors into high-limit tripouts. Learn how to differentiate between fouled condenser tubes, non-condensable air trapped in the circuit,…
⚠️ Identified System Fault Symptoms
- High pressure switch (HP) tripouts during afternoon heat
- Elevated compressor running current and high kWh bills
- Discharge pressure gauge needle vibrating violently
- Approach temperature exceeding 4.0°C
