What is a Chiller Overhaul?
Part of the lifetime maintenance of a chiller, an overhaul replaces wearable parts before they fail. We focus on the compressor as it contains the most critical wearable components. The goal is to return your equipment to its original peak performance.

KEY OVERHAUL BENEFITS
RELIABILITY
Reduced Downtime
Planned interventions eliminate the risk of surprise compressor failures.
Efficiency
Improved Performance
Restore units to original specs for optimal seasonal COP energy usage.
Strategy
Planned Low-Season Work
Schedule work during low cooling seasons for cheaper, stress-free execution.
Longevity
Extend Equipment Lifetime
Assure prolonged operational life for your facility's major capital investment.
Why Overhaul Before Compressor Failure?
An overhaul is a fundamental component of the lifetime maintenance of a chiller. The overhaul is focused primarily on the compressor, as it houses the most wearable mechanical parts in the chiller system, though complementary overhaul procedures across heat exchangers and electrical starters are also integrated into maintenance schedules.
Reduced Unplanned Downtime
Avoid unexpected shutdowns during peak cooling loads.
Cost Savings
Preventive actions dramatically reduce repair budgets.
Improved Reliability
Eliminate efficiency loss caused by mechanical wear & tear.
Planned Low-Season Work
Schedule interventions when chiller demand is naturally lower.
Total Peace of Mind
Focus on core facility business while Daikin manages chillers.
Extend Chiller Lifetime
Component replacement prolongs asset operating life.
Transform your chiller plant from a reactive asset into a smart, self-optimising facility. Daikin on Site (DoS) connects your equipment to a secure cloud platform, providing 24/7 continuous thermodynamic monitoring, automated efficiency benchmarks, and proactive energy drift alerts.
Universal Brand Support
Non-invasive hydraulic measuring kit connects seamlessly to Daikin chillers alike.
Automated Carbon Reports
Generate ISO 50001 energy compliance and CO₂ reduction reports with one click for ESG disclosure.
Predictive Anomaly Detection
AI-driven algorithms identify fouling, refrigerant loss, or setpoint drift before energy bills spike.
Real-Time COP Analytics
Instantly track live Coefficient of Performance (COP) and kW/Ton metrics under fluctuating weather and facility loads.
EU No 517/2014 Mandate
Enforced since 1 January 2015. Requires equipment operators to prevent emissions through periodical leak checks, certified servicing, and end-of-life gas recovery.
Halved Check Frequency
Installing an approved leakage detection system reduces required leak inspection frequency by 50% (e.g. 3 months → 6 months).
Prompt Repair Without Delay
When a leak is detected during inspection, precautionary containment actions must be taken and repairs completed without undue delay.
Lubricant Condition
Evaluates viscosity stability, additive depletion, and thermal breakdown limits.
Abnormal Wear
Spectrometric testing measures microscopic Iron (Fe), Copper (Cu), and Aluminum wear particles.
Internal Contamination
Detects harmful organic acids, moisture ingress, and chemical sludge build-up.
Mechanical Condition
Correlates chemical data with Daikin chiller historical operating data to provide precise action plans.
Non-invasive spectral diagnostics conducted while your chiller operates under full load. Daikin certified engineers measure vibration velocity (mm/s RMS) and frequency waveforms to isolate mechanical degradation months before visible or audible symptoms occur.

Actionable Health Report
An inspection probe is guided inside each individual tube of the heat exchanger. Any physical defects or wall thinning to the tubes cause a change in the eddy currents from their normal circular shape. Daikin engineers record these signals to produce a comprehensive diagnostic report identifying root causes and extent of damage.
