From initial commissioning through multi-year maintenance agreements, our service programs are designed to maximize uptime, optimize energy efficiency, and extend the operational life of every HitachiCool system in your facility.
Schedule a Service VisitFlexible service tiers to match your operational criticality and budget requirements.
Our factory-trained engineers manage end-to-end installation including mechanical fit-up, refrigerant charging, VFD parameter tuning, BMS integration, and performance verification. Each commissioning concludes with a documented baseline of operating parameters including superheat, subcooling, oil temperature, and vibration levels.
Quarterly or semi-annual inspections covering compressor oil analysis, refrigerant charge verification, condenser and evaporator cleaning, control calibration, and electrical connection torque checks. Our data-driven approach uses trending from IoT sensors to shift from calendar-based to condition-based maintenance scheduling.
Cloud-connected systems feed real-time data to our operations center. AI algorithms flag anomalies in compressor discharge temperature, approach temperature drift, and refrigerant charge loss before they escalate into failures. Remote firmware updates keep your controls running the latest optimization algorithms.
24/7 emergency dispatch with guaranteed 4-hour response for critical applications. Global parts distribution centers stock compressors, expansion valves, VFD boards, and sensors with 48-hour delivery to most regions. Temporary rental units available for extended repair scenarios.
Every commissioning and service visit follows a documented verification protocol.
Performance measured per AHRI Standard 550/590 conditions. We record leaving chilled water temperature, entering condenser water temperature, compressor power draw, and calculate real-time COP. Results compared against factory test data shipped with each unit.
For new customers evaluating our compressor or controls technology, we offer a 90-day trial deployment program. An application engineer installs the evaluation unit, configures monitoring, and provides weekly performance reports comparing measured vs. quoted specifications.
Service agreement clients receive annual energy performance audits comparing current COP degradation trends against the ASHRAE 90.1-2022 baseline. Audit reports include measured data, recommended maintenance actions, and projected energy savings from proposed upgrades.
Our flexible plans range from basic annual inspections to full-coverage 24/7 agreements with guaranteed response times.
