How a Texas Bitcoin Mining Facility Used A Multi-Layered Filtration Approach to Protect Air Intakes From High Wind Dust Infiltration

 

Background

Cholla Energy, a division of Cholla Inc., is a leader in energy exploration and development. Recently, the company expanded into bitcoin mining, an industry highly reliant on reliable energy and high-performing equipment. With over $1M in infrastructure and mining machines at stake, Cholla needed a robust air filtration solution to protect its investment at their newest site, maintain uptime, and ensure operational efficiency.

Challenge

Located in a semi-arid region of Mitchell County, TX, Cholla’s facility faces constant dust infiltration driven by high winds. The site uses  oil-based immersion fluid in a closed-loop system, circulating to dry coolers on the facility exterior as the primary method of cooling. However, radiant heat emitted by the tanks must also be effectively evacuated to maintain operation efficiency. Without proper mitigation, dust and dirt infiltration can lead to costly equipment damage, degraded mining performance, and extended payback periods.

The challenge:  to mitigate these risks, Cholla needed an industrial air filtration system capable of:

  • Withstanding high winds and dust infiltration
  • Maintaining optimal airflow while preventing overheating
  • Reducing maintenance labor and downtime
  • Extending the lifespan of mining hardware

Insight

Air filtration solutions are not one-size-fits-all. A custom solution that meets data center or crypto mining unique needs, work best in existing HVAC units to help drive more value from your equipment and extend its lifespan.

Selecting the right filter is about long-term performance, not just initial specs or cost.

Solution

RK Mission Critical, who built the site equipment, referred Cholla to Colorado Air Filter, a trusted air filtration distributor specializing in data centers. Keith Jordan, President of Colorado Air Filter, assessed Cholla’s site conditions and recommended a multi-layered filtration approach with Rensa products to enhance air intake protection and reduce maintenance time.

This Two-Tiered Filtration Strategy Included:

  1. PreVent Dual Ply Dust Screens: This line of UV protected PreVent screens was installed on the outside of the facility’s eight air intake hoods to serve as the first line of defense against airborne dust and particulates. Its flexible design and magnet mount system allow for quick installation without the need for drilling or tools, ideal for large-scale operations like Cholla.
  2. Mech 8 Washable MERV 8 Filters: Positioned inside the air intake hoods, these electrostatic air filters provide an additional layer of filtration by capturing finer particles that may bypass the PreVent screens. Their washable design ensures long-term cost savings and requires only periodic rinsing instead of frequent replacements.

Results & Impact

The results were clear:  Rensa’s advanced filtration system delivered four immediate and long-term benefits, including:

  • Reduced Maintenance Labor: At Cholla’s other sites, bag filter replacements required two technicians and eight hours per cycle. Rensa’s system saved them six hours per cycle by reducing cleaning to under two hours.
  • Long-Term Cost Savings: Unlike disposable bag filters that require continuous replacements, PreVent and Smith Filter’s Mech 8 washable filters are designed for extended use, with both types of air filters backed by a five-year warranty.
  • Optimized Performance: The filtration system helps prevent dust buildup to ensure efficient airflow and prevents overheating, which can lead to increased energy consumption and hardware failures.
  • Seamless Installation: The magnet-mounted PreVent screens allowed for easy, flexible installation and eliminated the need for extensive modifications to existing equipment. Available in a variety of models, frame and mount options, our PreVent line of filters is custom fit for any equipment air intake installation.

With years of proven performance and a strong return on investment, Rensa’s industrial air filtration solutions continue to help Cholla Energy protect its assets and maximize its mining capabilities in an industry where every second of uptime counts.

 

“Bitcoin mining is an energy-intensive business and every second of uptime counts.

Rensa’s filtration solutions have significantly reduced our maintenance time and helped protect our investment.”
