S&P Bitcoin Mining Upblast Exhast Fan

Soler & Palau STXB Upblast Centrifugal Roof Exhaust Fan – Belt Drive

The Soler & Palau STXB is a heavy-duty upblast centrifugal roof exhaust fan
engineered for high-performance ventilation in demanding industrial environments.

This belt drive model delivers up to 33,272 CFM across sizes ranging from 8″ to 48″,
making it the preferred choice for bitcoin mining container exhaust, large-scale crypto farms, and facilities requiring high static pressure capability. Its spun aluminum construction with
motor-out-of-airstream design ensures reliable performance in continuous-duty mining operations.

Soler & Palau STXB Belt Drive Construction

The STXB series features heavy-gauge spun aluminum housing with backward-inclined
centrifugal wheels designed for maximum efficiency and durability in mining environments.
The belt drive configuration keeps the motor isolated from hot exhaust air, extending
service life in high-temperature applications.

• Heavy-gauge spun aluminum housing with corrosion-resistant finish
• Backward-inclined centrifugal wheel for high efficiency and particle resilience
• Motor-out-of-airstream design protects against heat and contaminants
• Non-overloading wheel prevents stalling in high static pressure applications

Upblast Crypto Mining Fan Performance

This upblast centrifugal exhaust fan excels in crypto mining environments where
high static pressure and reliable airflow are critical for thermal management.
The STXB’s upward discharge design prevents hot air recirculation and efficiently
removes heat from mining containers and warehouse facilities.

• Airflow: Up to 33,272 CFM depending on model size (8″ to 48″ available)
• Static Pressure: Up to 2-3/4″ w.g. – handles long duct runs and restrictive layouts
• Motor: 1/4 to 7-1/2 HP range, custom higher HP available on request
• Drive: Belt drive provides lower RPM, quieter operation, and adaptable performance

Bitcoin Mining FAQ – STXB Upblast Exaust Fans

What CFM capacity do I need from an STXB upblast fan for a 2MW Bitcoin mining container operation?

For a 2MW mining container, calculate approximately 15-20 CFM per kW of power consumption to maintain proper temperatures. This means you’ll need 30,000-40,000 CFM total exhaust capacity. A single STXB36 or STXB42 model can handle this requirement, delivering 28,000-33,000+ CFM depending on static pressure conditions. The upblast design ensures hot air is discharged vertically away from the container, preventing recirculation that could reduce cooling efficiency.

How does the STXB’s static pressure capability handle long ductwork runs in warehouse mining facilities?

The STXB’s ability to generate up to 2-3/4″ w.g. static pressure makes it ideal for warehouse mining operations with extended ductwork, intake filters, and multiple bends. Unlike axial fans that lose performance quickly under static pressure, the STXB’s centrifugal design maintains consistent airflow even with restrictive installations. For every 100 feet of straight ductwork, expect approximately 0.1-0.2″ w.g. pressure loss, which the STXB easily accommodates while maintaining target CFM rates.

Can STXB upblast fans be speed-controlled for variable mining loads and seasonal temperature changes?

Yes, STXB belt-drive models are compatible with VFD (Variable Frequency Drive) speed control systems, allowing operators to adjust airflow based on ambient temperatures and mining load variations. During cooler months, reducing fan speed by 20-30% can significantly lower energy costs while maintaining adequate cooling. The belt-drive design also allows for pulley changes to permanently adjust operating speed for different seasonal requirements or facility modifications.

What mounting considerations are critical when installing STXB fans on mining container roofs?

STXB upblast fans require proper structural support due to their weight and wind load considerations. For container installations, reinforce the roof structure to handle the fan’s operational weight plus wind loads. Position the fan to maintain at least 1.5 times the fan diameter clearance from walls or obstructions to prevent air recirculation. The upblast discharge pattern requires adequate vertical clearance – typically 10-15 feet minimum – to prevent hot air from being drawn back into intake vents.

How do I calculate if an STXB upblast fan will prevent hot air recirculation in high-density mining operations?

Calculate the upward velocity at the fan discharge using the formula: Velocity (FPM) = CFM ÷ (Fan Area in sq ft). For effective hot air rejection, maintain discharge velocities above 2,000 FPM. The STXB’s centrifugal design concentrates airflow, typically achieving 2,500-4,000 FPM discharge velocities. This high-velocity upward discharge, combined with proper fan placement (minimum 10-15 feet from intake points), ensures hot exhaust air rises well above the facility before dispersing, preventing thermal recirculation that reduces cooling efficiency.
