Basin is a local cooling controller for air-cooled mines. It continuously finds the lowest-power safe exhaust-fan setting as weather and site conditions change, using the VFDs, miner telemetry, and power data already on site.

Every site is different. Basin measures the actual result on your equipment.
Basin measures the loads that change with airflow and tracks the fan speed that produces the lowest total site power.
Large facility fans can move bulk airflow more efficiently than thousands of small, high-pressure miner fans. Exhaust speed changes how much air-moving work the miner fans have to do themselves.
Mining ventilation is sized for difficult conditions. When ambient temperature falls, the same fan speed is not always necessary—and fan power falls rapidly as speed comes down.
Braiins measured about 19 W/°C of miner-power change across one S19j Pro-like test range at constant frequency, voltage, and hashrate.
In cold conditions, lower miner power can outweigh the additional exhaust-fan power. The lowest-total-power point can move above the fan-only minimum.
Weather changes. Miner count changes. Airflow changes. Basin makes bounded fan-speed tests, waits for settled readings, and follows the lowest safe total-power point as conditions move.
Thermal limits, miner-fan behavior, VFD response, stale telemetry, and local fallback rules take priority over savings.
Basin connects to your existing miners, power metering, and VFDs. It reads the site, finds the lowest-power safe fan setting, and adjusts fan speed through the control path you already use.
Existing telemetry. No firmware changes.
Existing PDU or site metering.
Existing VFDs and fans. No cooling-hardware replacement.
Basin retrofits the cooling controls already on site. Before travel, we confirm VFD access, miner telemetry, metering, network boundaries, and existing fallback behavior.
We confirm compatibility remotely before parts are ordered or travel is booked.
A local Basin controller connects to miner telemetry, power data, and the existing VFD control path. Miners stay online.
Every drive, safety limit, telemetry source, and fallback path is tested before Basin takes control.
Basin compares its operation with two fixed-speed reference policies measured on the same equipment. These references are defined by rule—not reconstructed from how the site used to operate.
One represents the obvious maximum-airflow policy. The other gives careful fixed-speed operation a strong, conservative comparison.
Facility fans stay at the site’s configured maximum—usually 60 Hz, but always the site’s actual limit. Basin records settled examples during the first sweep and later sweeps.
Once per month, Basin selects the lowest single fan speed that remained inside temperature and miner-fan-effort limits during the hottest conditions covered by recent sweeps.
The monthly reference gets the benefit of hindsight. It can use the hottest observed conditions when choosing one fixed speed for the month, making it intentionally difficult for Basin to beat.
Nearly all of the power in the report is read straight off a meter. The one calculated piece is the smallest, and the number behind it is measured on your own fans at install.
Every number is labeled. The report always shows which meter, drive, or calculation a value came from.
Basin only compares an hour against a reference hour recorded on your own site under conditions like it.
Signed, not selective. Hours where Basin used more power are reported exactly the same way.
Every hour ships with its meter values, fan speeds, the calibration number, the reference it was matched against, and the result.
Basin already knows how each zone normally responds to fan speed, temperature, miner load, and weather. When that relationship changes, it becomes an operational signal.
Basin checks whether temperature, fan, power, and drive signals are fresh and plausible before using them for control or reporting.
Basin compares commands with actual drive and cooling behavior, exposing failed fans, VFD faults, and equipment that stops responding normally.
Miner fans that climb faster than expected can reveal restrictions, recirculation, or thermal deterioration before it turns into throttling.
Basin continuously measures what normal cooling performance looks like. That makes gradual changes visible—not just hard failures and high-temperature alarms.
Pod B airflow performance has degraded under comparable temperature and miner load.
The result: the same system reducing cooling power also becomes a live view of cooling health, equipment response, and airflow deterioration across the site.
Basin grew out of operating multi-megawatt air-cooled mines—managing thousands of miners, curtailment, VFDs, firmware testing, monitoring, and cooling problems in production.
Not a controls product designed in isolation.
Built around noisy telemetry, equipment variation, and real operating constraints.
Stale data, failed drives, bad commands, airflow restrictions, thermal limits, and communications loss are treated as normal operating realities.
$3,000 + $250 per controlled VFD to install. $0.15 per miner per month after go-live.
Payment terms: A $3,000 project deposit is applied to the installation total. The remaining balance is due at commissioning.
Installation$3,000 + (12 × $250) = $6,000
Payment$3,000 deposit + $3,000 at commissioning
Subscription2,000 × $0.15 = $300/month
We review fan-drive access, PLC and fallback behavior, miner APIs, metering, firmware, network boundaries, and zone layout. You get a clear answer on fit, missing data, and any nonstandard work before the project deposit is invoiced.
