Advanced Air Filtration & Climate Control for Indoor Farming and Controlled Environment Agriculture (CEA)

GHT Solutions provides innovative air filtration and ventilation products designed specifically for greenhouses, vertical farms, and all types of controlled environment agriculture (CEA). Our EPP filter boxes and duct coolers/heaters with circular connections ensure stable, clean air and precise climate control—critical for healthy plant growth, disease prevention, and maximum yields.

Our solutions for indoor farming include:

EPP Filter Boxes: Multi-stage filtration (pre-filter, F7, carbon) removes dust, pollen, mold, and harmful particles, creating an optimal environment for crops and research.
Duct Coolers/Heaters with Circular Connections: Versatile climate control units that operate with water or glycol, suitable for use with or without heat recovery (HRV/ERV) systems. Quick to install and compatible with D200/D250 ductwork.
Energy-Efficient Design: EPP material provides outstanding thermal and sound insulation with minimal air leakage, reducing energy costs and supporting sustainable agriculture.

With GHT, you get reliable, easy-to-integrate solutions trusted in commercial greenhouses, vertical farms, and research facilities across Europe and North America.

Breathe clean, controlled air and boost your indoor farm’s productivity—choose GHT Solutions for your next CEA project.

Key Benefits

✔ Superior Air Purity – Removes 99% of particles >3µm and 95%+ of VOCs
✔ Long-Lasting Performance – Anthracite carbon lasts 2–3x longer vs. standard activated carbon
✔ Energy Efficient – Low ΔP (≤45 Pa @ 500 m³/h) reduces HVAC costs by 15–20%
✔ Humidity Resistant – Stable in up to 90% RH (vs. coconut carbon degradation at 70% RH)
✔ Explosion-Safe – Non-sparking anthracite (auto-ignition >450°C)

Ideal Applications

✔ Cannabis Cultivation – Controls terpenes (β-myrcene 96%) and prevents cross-contamination
✔ Vertical Farms – Reduces ethylene (89%) to extend shelf life of leafy greens
✔ High-Humidity Greenhouses – Stable in tropical conditions (90% RH)
✔ Organic Farms – Certified for pesticide/fertilizer odor scrubbing
