LG Shows Data Center Cooling From Chillers to Immersion at HARFKO

The liquid side was CDUs, which move coolant between the facility loop and the servers, and cold plates that take heat directly from chips. LG also displayed immersion cooling solutions, with an immersion tank that is still under development, per Financial News.

None of the reports give a CDU rating, a coolant temperature, a flow rate or a rack density for the HARFKO exhibits. The only hard number LG has published recently is from April, when its newsroom described a 1.4 MW CDU with inverter-driven pumps at Data Center World 2026 in Washington, D.C. That is LG's own figure and was not repeated at HARFKO.

Why LG's Cooling Lineup Matters for Capacity

A vendor that sells the whole thermal path matters to operators because chillers, CDUs and cold plates have to be matched on temperature and flow. LG is pitching all of it from one catalogue, plus management software it showed in April that monitors CDUs, room air handlers and chillers.

For Voltgrid readers the signal is supply breadth, not performance. A mainstream HVAC maker with chiller, CDU and immersion products adds to the list of cooling suppliers beyond the specialist liquid-cooling firms. Without ratings, though, buyers cannot yet compare LG's kit with rivals on kW of heat removed per unit.

The immersion line builds on LG's tie-up with Green Revolution Cooling, with which, its April newsroom post said, LG developed the immersion tanks shown in Washington. Voltgrid News reported that LG, GS E&C and GRC have teamed up on standard immersion cooling designs for AI.

Lee Jae-sung, president and head of LG's Eco Solution business division, said LG will keep expanding solutions built on its "Core Tech" component competitiveness across cooling needs from homes to AI data centers. Of the Multi V 7, LG says the new compressor improves performance, efficiency and stability over existing products, but the coverage gives no numbers.

What LG Has Not Confirmed Yet

LG has not disclosed capacities, supply and return temperatures, availability dates, prices or customers for the equipment shown at HARFKO. The immersion tank has no release date. The next detail to watch is a rated CDU or chiller specification for the Korean market.
