Field Notes

Guides and observations on hydro-cooled mining equipment, loop maintenance, and heat-sensitive installations in South Korea.

Why 0.05 EH/s Is the Basement Threshold

How we use the 0.05 EH/s band as a practical floor when advising hydro-cooled cabinets in heat-sensitive Korean buildings.

Coolant Inhibitor Ratios in Humid Summers

Field notes on glycol and inhibitor mixing mistakes we see in Korean hydro mining loops during July and August.

Negotiating Landlord Heat Limits Before Energisation

How commissioning reports help Korean operators satisfy upstairs tenants on outlet water temperature and noise.

Pump Head Margin After Import Customs

Why newly imported hydro cabinets sometimes underperform until pump curves are verified on Korean water pressure.

Practical writing from commissioning visits and audit work — hash-rate stability, coolant chemistry, building constraints, and seasonal derating in Korean climates.
