On October 8, 2026, Hi-M Solutek, a subsidiary of LG, expanded its HVAC maintenance program for AI data centers. The company will now service liquid-cooling equipment, including coolant distribution units (CDUs) and direct cooling systems (TCS), which deliver liquid directly to server racks. This upgrade adds dedicated engineers on site, specially trained technicians for complex repairs, 24/7 remote monitoring via LG’s BECON Cloud platform, and stocked parts to speed up fixes. The change affects contractors, property managers, and equipment sellers working with high-density AI computing facilities.

Compliance and contracts for liquid-cooling retrofits

When upgrading AI data centers with liquid cooling, it’s crucial to follow ASHRAE TC 9.9 thermal guidelines. These rules help ensure the cooling design manages heat safely and efficiently. You also need to meet local authority codes, including leak detection and containment plans to prevent damage from coolant spills. Service contracts should clearly define service-level agreements (SLAs). These must include 24/7 remote monitoring, how alarms are communicated, on-site response times, and who owns spare parts. Proper training is essential for staff handling coolant fluids like water-glycol mixtures or dielectric liquids that don’t conduct electricity. Technicians must also follow electrical lockout procedures to stay safe during repairs. If chillers remain part of the system, staff must understand EPA refrigerant regulations to avoid environmental violations. Clear compliance and contract terms protect operations and reduce costly downtime risks.

Where the revenue is: uptime SLAs and stocked spares

AI data centers run nonstop, so any cooling downtime can hit operations hard. This makes maintenance contracts more valuable and less sensitive to price. Contractors can boost their revenue by offering fixed-fee plans that bundle remote monitoring, regular inspections, and emergency response. This approach guarantees steady service and predictable costs for customers. Keeping key parts in stock—like pumps, seals, filters, and sensors—helps technicians fix issues faster. Faster repairs mean less downtime and happier clients. It also supports steady contract renewals since centers rely on quick solutions to avoid costly outages.

On-site changes: CDUs, liquid loops, sensors, and alerts

A coolant distribution unit, or CDU, is the central hub for liquid cooling. It includes pumps, heat exchangers, filters, and controls that deliver cooled liquid to server racks. Direct cooling systems, or TCS, route liquid coolant directly to the computer chips. These systems require sensors to monitor flow, temperature, and leaks. If any sensor detects an issue, alarms trigger safe shutdown procedures to protect equipment. LG’s BECON Cloud platform enhances this setup by providing remote monitoring. It collects real-time data and tracks trends to spot potential problems early. When measurements go outside normal ranges, the system sends alerts and can automatically dispatch technicians. This combination of on-site hardware and cloud alerts helps reduce downtime and keeps AI data centers running smoothly.

Action plan for contractors, managers, and sellers

Contractors should start by identifying gaps in their skills related to liquid cooling. Enrolling in specialized training will help handle coolant distribution units (CDUs) and direct cooling systems confidently. Setting up 24/7 on-call support ensures quick response to emergencies. Partnering with original equipment manufacturers (OEMs) can provide access to expert knowledge and specialized parts. Property managers need to review service level agreements (SLAs) carefully. These should cover both air and liquid cooling loops, including alarm routing and response times. Pre-staging critical spare parts on site can reduce downtime during failures. Equipment sellers should expand their product lines to include CDUs, valves, hoses, sensors, and service kits designed for liquid cooling. Offering fast-ship programs helps contractors and managers get parts quickly when time is critical. Together, these steps prepare all parties to support the growing demand for reliable AI data center cooling.
