One of the most compelling applications of immersion cooling is its ability to produce high-grade thermal exhaust at steady temperatures of 60°C to 65°C. Unlike air-cooled mining containers that discharge diffuse 38°C air into the atmosphere, liquid systems concentrate 95%+ of the dissipated electrical energy into a pumped fluid loop that can be plumbed directly into hydronic heating circuits.
Project Overview: Gimpo Agricultural Collaboration
Between November 2025 and March 2026, Focus Connect Core collaborated on an engineering project connecting a 250kW immersion test rig to an adjacent commercial strawberry greenhouse in Gyeonggi-do:
- Thermal Load: Approximately 235kW of steady thermal energy was extracted continuously from 70 immersion-cooled ASIC units.
- Heat Delivery: A secondary water-glycol loop delivered 55°C water to root-zone radiant PEX piping laid under elevated strawberry growing benches, maintaining 18°C soil temperatures despite outdoor lows of -12°C.
- Results: The greenhouse eliminated three kerosene-fired hot water boilers, saving over ₩32,000,000 KRW in winter fuel costs over four months.
Thermal Backup & Summer Shunt Design
Because agricultural heating demand drops to zero between May and September, a dual-manifold 3-way motorized diverting valve system was integrated to route dielectric fluid heat through the outdoor dry coolers whenever greenhouse temperature sensors reached setpoint.
We examine this exact mechanical schematic, including pump curves, fail-safe bypass valves, and anti-freeze glycol ratios, in our 2-Day Heat Recapture & Hydronic Systems seminar.
