About BC40 MEGA

The BC40 MEGA is a high-density immersion cooling design with the goal of providing a full-stack solution for large-scale mining customers. It integrates all required devices such as power distribution cabinets, smart PDUs, network interfaces, controllers, cooling tanks, circulation ducts, etc. Aims to provide miners with a turn-key mining installation.

Fog Hashing uses single-phase immersion cooling technology for cooling miners or servers. By immersing the miner in dielectric coolant, the heat generated by the ASIC chips is transferred to an external cooler or other dissipation equipment through specially-designed fluids. The precise control of the circulating fluids keeps the chipsets running at their optimum performance. Dust-free and static-free environment greatly reduces maintenance costs. Adaptive thermal design results in extremely low power consumption for heat dissipation (PUE<1.05).

Product Features 

Independent modular design

The BC40 MEGA container contains 16 cooling tanks, and each tank is independently connected to the dry cooler or cooling tower. Each Tank can accommodate 24 Antminer S19s.

Single-loop circulation

There is an independent circuit between each cooling tank and the dry cooler/cooling tower (for 8 dry coolers/cooling towers, 16 independent circuits), easy to deploy, and maintenance without interference

Smart PDU

The BC40 MEGA container contains 32 24-port smart PDUs, including networks, switches and sensors. Current monitoring and leakage protection. Can check the running status and manage switches in the LAN.

Redundant design

Power load and cooling capacity, with enough safety margin, to allow ultimate overclocking. Adapts to most temperature environments. EC dry cooler fans and pumps with adjustable speed.
