Ventilation for Cryptocurrency Mining Centers
Ventilation of crypto mining facilities requires an detailed design process because the mining location sites are so diverse. A typical cryptocurrency mining facility or data center has machines, aptly known as rigs, stacked on racks. These machines come in different sizes and depend on the target cryptocurrency. Bitcoin mining is mainly done with ASIC (chip) machines, with more powerful and efficient chips coming out every few months.
Cryptocurrency/ bitcoin mining centers produce a tremendous amount of heat. Purging this heat from the data centers is important because the facility’s ambient temperature directly impacts its bottom line. Most mining rigs have internal controllers that adjust the voltage and clock speed of the rig according to the surrounding temperature. Moreover, a temperature higher than 149° F can damage the hardware and must be carefully monitored.
An industrial ventilation system is a significant consideration in a cryptocurrency data center design where the ventilation system constantly monitors the internal environment and adjusts critical airflow.
Design considerations include:
- Air changes per hour (ACH)
- Amount of particulate in the ambient airstream.
- BTUH/Wattage for heat rejection
- Solar loads
- State and local ordinances
- Permissible Noise Levels (PNL)
- Equipment layout within the enclosure or dedicated facility location
- Stratification of air temperatures within a facility
- Site location
- Local weather patterns
- Available power
Components for the ventilation system:
- Supply and exhaust fans – wall or roof mounted configurations
- Fan silencers
- Louvers, dampers & diffusers
- Air filters
- Filter racks or housings
- Intake hood (s) – weather designs
- SysTech custom ventilation modules
- Electrical control packages
Cryptocurrency mining can be placed in dedicated containers or new/ existing buildings constructed of brick, block, or stick build construction. The mining area may be a small part of a much larger facility. Typically, large volumes of outside air are supplied and moved through the process by roof or wall openings and fan-powered ventilation modules to exhaust the warm air from the container or space.
Each ventilation design package is tailored to available utilities, local weather conditions, ambient air quality, occupational safety and comfort, noise criteria, and specific requirements required by a client.
Essential criteria when designing cryptocurrency ventilation systems:
- Heat – large volumes of heat need to be exhausted from the building or container.
- Noise – Noise is generated by ventilating fans and needs to be addressed with noise mitigation at the facility and sometimes for the community surrounding the facility. Noise levels at property lines can significantly depend on local ordinances. SysTech has addressed mitigating building noise with custom-designed Lo-Noise™ ventilation modules.

- Ambient particulate or dust – Outside air needs to be filtered as it enters the enclosure.
- Other factors determining the final design include the geographic location of the facility, equipment installed, heat loads, and on-site staffing.
