According to a recent LinkedIn post from Bitmain, its ACS (ANT COLD STORAGE) solution is designed to provide supplemental cooling for data centers without continuous make-up water during normal operation. The post positions the system for hot, water-scarce regions where water costs, usage limits, and permitting requirements may affect facility siting and operations.
The post’s reference calculations compare annual water consumption of about 8,000 tons for a 1 MW evaporative pad system and 9,000 tons for a wet cooling tower with zero make-up water for the ACS-based approach. Each unit is described as storing roughly 8 GJ of cooling capacity and providing about six hours of supplemental cooling for a 2 MW hydro-cooling container during peak heat.
For investors, the technology could strengthen Bitmain’s positioning in data-center infrastructure by addressing water availability alongside computing and energy requirements. Reduced reliance on water may expand deployment options in arid markets and help operators manage regulatory or operating-cost pressures, although the commercial benefit will depend on local electricity prices, water costs, climate, and integration requirements.
The post cites an estimated payback period of approximately two years, while noting that the figure is an internal reference estimate rather than a guaranteed return. Adoption prospects will therefore depend on independently validated performance, upfront equipment costs, maintenance needs, and whether customers prioritize water conservation sufficiently to justify investment in closed-loop cooling capacity.
