Green Steel, Carbon Capture, and Hydrogen Production require a new class of industrial fan. Higher Pressures. Higher Temperatures. Zero Leaks.
Traditional blast furnaces are closing. Direct Reduced Iron (DRI) plants using Hydrogen are replacing them.
Moving hot hydrogen gas (H₂) requires ATEX-certified, gas-tight fans that can handle 800°C+ temperatures without leaking explosive gas. Standard industrial fans were never designed for this.
Double-mechanical seals and buffer gas systems to prevent H₂ leaks. Certified for ATEX Zone 1 explosive atmospheres.
Key Feature: Nitrogen buffer gas purge prevents hydrogen from reaching bearing assemblies
Fans designed to recirculate 1000°C gas to pre-heat incoming iron ore pellets, reducing OPEX by up to 30%.
Key Feature: Heat-resistant steel alloys (Inconel, Hastelloy) rated for continuous operation
Electric arc furnace (EAF) ventilation systems that handle high-dust, high-temperature exhaust with minimal maintenance.
Key Feature: Wear-resistant coatings and oversized dust clearance tolerances
The EU Green Deal mandates that steel producers reduce carbon emissions by 55% by 2030. Traditional blast furnaces cannot comply. H₂-DRI is the only viable path forward for European steel.

Cement kilns must capture their CO₂ to avoid massive taxes. This involves pushing dirty exhaust through massive "Scrubber" towers filled with chemical solvents (amines).
The Challenge: Standard draft fans cannot overcome the pressure drop across these towers (500+ Pa). The corrosive, wet exhaust destroys mild steel components within months.
Up to 2000 Pa static pressure
These fans must overcome the massive resistance of the scrubber tower while maintaining continuous 24/7 operation without failure.
Chemical-grade materials
The exhaust contains sulfur, wet amines, and corrosive compounds. We build fans from industrial-grade alloys designed for chemical service.
A typical 3,000 tonne/day cement plant generates approximately 2,100 tonnes of CO₂ daily. To capture 90% of this requires:
Without EVG Fans: Standard HVAC equipment would fail within 6-12 months due to corrosion and pressure limitations.
With EVG Fans: 10+ year operational life with predictable maintenance schedules and zero unplanned shutdowns.
The EU's Carbon Border Adjustment Mechanism (CBAM) taxes imported cement, steel, and chemicals based on their carbon intensity. For a cement plant emitting 2,100 tonnes/day, this could mean €3-6 million per month in tariffs without carbon capture.

Electrolysis halls generate massive heat and potential hydrogen leaks. Even a 0.5% H₂ concentration in air is a serious explosion hazard.
Industry Standard: Hydrogen must be diluted below 4% Lower Explosive Limit (LEL) by continuously exhausting and replacing hall air. This requires moving hundreds of thousands of cubic meters per hour.
Massive ATEX-rated axial fans (TunnelTech design) that clear the hall air volume every 60 seconds to prevent explosive gas buildup.
Up to 500,000 m³/hr per fan for large electrolyzer halls (10+ MW installations)
ATEX Zone 1 & 2 certified for operation in explosive atmospheres
Critical Design Feature: Spark-free aluminum construction, grounded motor housings, and explosion-proof electrical connections prevent ignition sources. Emergency shutoff systems integrated with H₂ detection sensors.
Electrolyzer stacks generate waste heat. Our ventilation systems remove heat while maintaining safe H₂ dilution ratios.
H₂ is lighter than air and accumulates at ceiling level. Strategic fan placement ensures uniform air mixing.
Multiple fans operate in parallel. If one fails, the system maintains safe ventilation rates automatically.
