Equipment Health Monitoring for Chillers & HVAC Systems
Engineering-based health monitoring for chillers, HVAC systems and cooling infrastructure that detects performance degradation before it becomes an energy, reliability or maintenance problem.

Every engineering parameter tells a story.
RHYDAK correlates refrigeration cycle, hydraulic performance, compressor loading, heat transfer and control behaviour to identify equipment degradation before performance, reliability or energy consumption are affected.
Heat Transfer Performance
- • Evaporator Approach
- • Condenser Approach
- • Discharge Superheat
- • Liquid Subcooling
- • Saturation Temperatures
- • Heat Exchanger Fouling Trend
Compressor Reliability
- • Compressor Lift
- • Motor Current
- • Oil Differential Pressure
- • Oil Temperature
- • Bearing Temperature
- • Operating Envelope
Evidence-Based Diagnosis
- • Root Cause Identification
- • Progressive Degradation Trend
- • Reliability Assessment
- • Condition-Based Maintenance
- • Remaining Performance Margin
- • Engineering Recommendation
One abnormal value does not indicate a fault.
A high condensing temperature, low COP or elevated motor current does not independently identify the problem. RHYDAK correlates dozens of thermodynamic, hydraulic, electrical and control relationships simultaneously before identifying the engineering root cause.
Collect Multi-System Evidence
Temperatures, pressures, flow, power, compressor loading, VFD behaviour, control response and historical trends.
Reject False Causes
Different faults often produce similar symptoms. RHYDAK eliminates unlikely causes using engineering relationships before identifying the actual degradation mechanism.
Identify Root Cause
Instead of reporting alarms, RHYDAK explains why performance changed, what component is responsible, and what engineering action should be taken.
High Condensing Pressure Investigation
Condenser fouling is the most probable cause.
Cooling tower degradation is unlikely because condenser water ΔT remains within the expected operating range.
Engineering inspection should first focus on condenser tube cleanliness before investigating refrigerant charge or compressor condition.
Knowing the fault is only the beginning.
Engineering intelligence should lead to the correct maintenance strategy. RHYDAK prioritises actions based on equipment condition, performance impact, reliability risk and operating criticality.
Healthy
Equipment operating within engineering limits. Continue monitoring and performance trending.
Monitor
Progressive degradation detected. Schedule engineering inspection during planned maintenance.
Plan Intervention
Performance deterioration is affecting plant efficiency. Corrective action should be prioritised during the next shutdown.
Immediate Action
High reliability risk or severe thermodynamic deviation. Immediate engineering intervention recommended.
Engineering intelligence across the complete cooling infrastructure.
Equipment health cannot be assessed by evaluating chillers alone. RHYDAK correlates the operating behaviour of every major component influencing cooling plant performance.
