The HD5 manual marks another major break in the Bitmain container line. The document describes two A/B liquid-cooling systems that can run independently or together while sharing a main control cabinet.
That architecture changes deployment, operations, and maintenance, so crews need to read the manual through planning and service work, not installation alone.

Comparison
Bitmain ANTSPACE HD5 V1 Dry Cooling Tower Guide: Version Differences
- HD5 introduces two A/B liquid-cooling thermal systems that can run separately or together while sharing a main control cabinet.
- The container grows to support up to 308 S21/S19 Hydro servers, well above the 210-unit HK3 and HW5 families.
- Power scales up sharply: 1512 kW standard, 1665 kW maximum, and 1200A x4 main switching capacity in the distribution layer.
- HD5 uses a dry-cooling-tower system with a 1500 kW tower package and DN100 external interfaces instead of HW5's dry-wet branch.
Quick Specs

| Dry cooling tower capacity | 1500 kW |
| Interfaces / flow | DN100 PN16 external interface, rated flow 67.2-73.9 m3/h depending on pump frequency |
Installation
Bitmain ANTSPACE HD5 V1 Dry Cooling Tower Guide Setup Highlights
- Level the container, install the dry-cooling towers, lift them into place, and lay out the intermediate connection pipework exactly as the HD5 guide shows.
- Treat the A and B cooling systems as a commissioning concern from day one because the manual describes them as separate loops that can run independently.
- Use the distribution-work chapter carefully because HD5 has a heavier electrical and switching profile than HK3 or HW5.
- Complete the onsite installation summary before power-up so the A/B loop architecture is fully validated.
Utilities
Bitmain ANTSPACE HD5 V1 Dry Cooling Tower Guide Power and Cooling Requirements
- HD5 uses forced-air dry cooling towers only in this manual, not dry-wet or PHE variants.
- The container supports 1512 kW standard power and 1665 kW maximum power, with 1200A x4 main switching capacity.
- The dry cooling tower package is rated at 1500 kW and <=80 kW operating power.
- Rated flow is shown as 67.2-73.9 m3/h depending on pump frequency, which is different from the >=85 m3/h target used in the HK3/HW5 manuals.
Operations
Bitmain ANTSPACE HD5 V1 Dry Cooling Tower Guide Operation Notes
- The manual covers system use, pressurization, rehydration, electrical wiring, power-up/power-down, and touch-screen operation from the perspective of the A/B system split.
- Operators can energize loop A, loop B, or both depending on the site's configuration and available server population.
- Field builds using dual-loop HD5 architecture should stay on this manual instead of the single-loop HK3 or HW5 guides.
- The larger server count and heavier power profile make disciplined startup sequencing even more important on HD5.
Maintenance
Bitmain ANTSPACE HD5 V1 Dry Cooling Tower Guide Maintenance Notes
- The HD5 guide includes dedicated container troubleshooting, dry cooling tower troubleshooting, and maintenance/upkeep sections.
- Because the system can run as A, B, or both, maintenance planning needs to account for loop isolation and staged service windows.
- HD5 is not the place to improvise with HK3/HW5 service habits; the guide's own architecture differences justify a separate maintenance playbook.
- Use the HD5 guide to compare expansion plans against smaller Bitmain container families.
Troubleshooting
Bitmain ANTSPACE HD5 V1 Dry Cooling Tower Guide Troubleshooting Notes
- Use the HD5 manual first when the site has an A/B loop issue, because that architecture does not exist in HK3 or HW5.
- The dry cooling tower troubleshooting section is separate from the container troubleshooting section, which helps isolate whether the problem is in the loop or the tower package.
- HD5's power scale means distribution and loop-state checks should happen before server-level assumptions are made.
