Antminer S19 XP — Warehouse Row Review

Bitmain’s S19 XP clears our 0.05 TH/s threshold comfortably at 140 TH/s nominal. We ran two units in a standard 42U open-frame rack inside a 1,400 m² warehouse near Daegu with 28°C ambient intake.

Rack Fit

At 195 mm depth, the S19 XP leaves 85 mm clearance to the rear door on a 800 mm deep rack — enough for a 60 mm hot-aisle gap when rows face each other across a 1.2 m aisle. Rear exhaust velocity was measured at 4.2 m/s, which pushed hot air into the containment channel without recirculating into the cold aisle when baffle panels were sealed at floor level.

Canaan Avalon A1466 — Compact Row Review

The Avalon A1466 pushes 170 TH/s, making it one of the denser options we have tested in sub-metre aisles. Canaan’s side-intake design changes how rows must face in a warehouse block.

Side Intake Consideration

Unlike rear-exhaust Antminers, the A1466 pulls air from the left panel. In a cold-aisle/hot-aisle layout, all units in a row must face the same direction so intakes align with the cold aisle. Reversing one unit in a bay creates a local hot spot that raised chip temps 11°C in our test.

Power & PDU Audit

For operators who already have hardware hashing but suspect breaker trips or uneven phase loading, this audit maps every PDU circuit against actual wall draw.

Deliverables

• Phase balance report across all three legs
• THD measurements at the main panel
• Revised PDU schedule with recommended breaker upgrades
• Red-line markup of existing floor plan showing overloaded bays

Typical Findings

Mixed batches of S19 and M50 units on the same PDU often create 15–20% phase imbalance. We specify which units to move to which bay to flatten the load without downtime exceeding four hours per row.

Warehouse Layout Assessment

Who This Assessment Is For

Warehouse operators planning a new mining row or expanding an existing cold-aisle block need more than a equipment spec sheet. This assessment is for facility owners, co-location hosts, and install crews working in industrial units between 200 m² and 5,000 m² who want a marked floor plan before ordering hardware.

What You Receive

• Marked floor plan showing rack positions, hot-aisle and cold-aisle orientation, and forklift clearance paths
• Equipment shortlist matched to your contracted kW capacity, filtered to units above 0.05 TH/s
• PDU and breaker schedule per bay with headroom calculations for three-phase feeds
• Phased install sequence so electricians, riggers, and network teams can work without blocking each other
• Airflow notes flagging recirculation risks when containment panels are partial or absent

Scope and Process

1. Initial call — You share floor dimensions, ceiling height, existing PDU layout, and power contract (kW and voltage).
2. On-site walkthrough (1–2 days) — Our engineers measure aisle widths, note intake/exhaust paths, and photograph cable-tray routes.
3. Draft plan review — We send a PDF floor plan within three business days of the visit. You mark revisions.
4. Final report delivery — Bound report with equipment table, install sequence, and annotated photos.

What Is Included

• Up to two site visits within 30 days of booking
• Floor plan in PDF and DWG format
• Equipment table with hashrate, wall power, rack depth, and aisle clearance per unit
• Email support for 14 days after final delivery

What Is Excluded

• Electrical installation or PDU procurement
• Structural engineering sign-off for mezzanine loads
• Network cabling and switch configuration
• Ongoing monitoring after install

Pricing

Assessments start at ₩2,800,000 for warehouses up to 800 m² with a single electrical feed. Larger facilities or sites requiring containment redesign are quoted after the initial call. A 30% deposit secures your visit date; the balance is due on final report delivery.

Whatsminer M50S++ — Aisle Clearance Review

MicroBT’s M50S++ registers 150 TH/s in our climate chamber, well above the 0.05 TH/s review threshold. We installed four units in a hot-aisle row at a co-location facility in Gyeongsangbuk-do.

Aisle Width Requirements

The unit’s 410 mm width plus cable bend radius needs a minimum 1.35 m aisle for safe PDU swap without shutting the adjacent bay. At 1.2 m — common in older Korean industrial units — technicians had to approach from the hot-aisle side only.
