Practical Hashrate & Immersion Lab (2-Day Gippsland Workshop)
An intensive 16-hour hands-on technical workshop at our Cowwarr test bench covering dielectric fluid thermodynamics, 415V three-phase sub-board balancing, brazed plate heat exchangers, and dry-cooler installation.
Who This Is For
Rural property owners, electrical tradespeople, self-managed mining operators, and facility engineers seeking real mechanical immersion experience.
Practical Knowledge & Bench Outcomes
- Operate single-phase dielectric fluid immersion tanks safely with real Antminer and Whatsminer hardware
- Calculate flow rates, heat dissipation in kWth, and fluid viscosity changes across 25°C to 65°C operating cycles
- Wire and meter 415V three-phase PDUs with neutral-current harmonic mitigation for dense inductive loads
- Plumb closed-loop cooling circuits with primary/secondary water pumps, brazed plate heat exchangers, and dry coolers
- Tune custom ASIC firmware voltage/frequency tables for high-density immersion without triggering chip overheating faults
Curriculum & Session Schedule
Thermodynamics & Dielectric Fluid Dynamics
Examining fluid viscosity, pump head calculations, material compatibility with seals/cables, and heat transfer coefficients comparing air vs engineered dielectric fluids.
ASIC Teardown & Immersion Prep
Removing stock fans, installing fan spoofs, cleaning thermal paste, installing upgraded thermal pads, and submerging hashboards into live test tanks.
Three-Phase 415V Power & Switchboard Distribution
Calculating continuous thermal load, neutral wire sizing for non-linear power supplies, C-curve vs D-curve breaker selection, and grounding loops.
Heat Exchangers, Dry Coolers & Firmware Overclocking
Plumbing brazed plate exchangers, sizing external dry cooler radiators for 40°C Victorian summer ambient temps, and calibrating dynamic per-chip autotuning.
Scope & Equipment Exposure
Comprehensive mechanical, electrical, and firmware calibration on live 40kW immersion testing units and air-cooled diagnostic rigs.
What Is Included
- 2 full days of direct bench access with live ASIC hardware and dielectric test tanks
- Course handbook containing Australian AS/NZS 3000 compliance guidance for continuous high-draw electrical installations
- Safety PPE kit (nitrile immersion gloves, ESD wrist strap, safety eye protection)
- Lunch, morning tea, and Gippsland roasted coffee on both days
- Custom calculation spreadsheets for fluid flow, CFM air pressure drop, and solar curtailment sizing
- Certificate of Completion and 30-day post-workshop technical support hotline access
What Is Excluded
- Accommodation and personal travel to Cowwarr, VIC
- Personal mining hardware (bench test units are provided, though attendees may bring one personal machine for diagnostic evaluation on Day 2)
- Certified electrician sign-offs (we teach electrical engineering design, but formal grid connections require your licensed electrician)
Lead Instructor & Prerequisites
Lead Instruction: Led by Craig Sterling (Senior Power Systems Engineer & Thermal Specialist) and Lachlan Reid (Hardware Diagnostic Technician).
Preparation: Basic understanding of electrical terminology (volts, amps, watts) is helpful. Bring a sturdy pair of work boots and a laptop for telemetry exercises.
Constraints & Class Size: Workshops are restricted to 6 attendees per session to guarantee each participant gets hands-on time wiring switchboards and operating the immersion pump stations.
