IOMTEK
Who are we?
IOMTEK is a climate-tech startup delivering innovative radiative cooling films that cut heat without electricity, water, or chemicals. From greenhouses to buildings and vehicles, our solutions lower temperatures by up to 10°C, boost agricultural yields by up to 7x — proven in African pilot farms, and reduce energy costs. Tested across Asia, Africa, and Korea, IOMTEK empowers communities to adapt to climate change with sustainable, high-impact technology. We’re proud to partner with farmers, builders, and innovators to create a cooler, more resilient future.

Product & Technology
IOMTEK’s greenhouse film integrates nanomaterial layers that provide:
-
Up to 18°C temperature reduction (e.g., 35°C → 17°C)
-
UV reflection & light diffusion for improved plant growth
-
Highly conductive & durable material suitable for long-term installation
-
Sustainable thermal regulation without active cooling
Traction
-
PoCs in Uganda, Malawi, and Vietnam with strong results
-
Licensed for commercialization via Yonsei University (30% revenue-sharing clause)
-
Active planning for PoCs in:
Naivasha (Kenya – floriculture) -
Western Cape (South Africa – vineyards)
-
Early-stage partner interest for container-based shipping and warehousing
Key Differentiators
-
50% cheaper than current cooling systems
-
High performance: 10–15°C cooling in real-world trials
-
No electricity, no corrosion, no toxic materials
-
Proven in high-heat regions (Qatar, Malaysia)
Why Africa?
-
Rising temperatures → significant yield drops
-
Water scarcity → need for passive climate control
-
Weak greenhouse performance in hot zones
-
IOMTEK offers a low-water, pesticide-free, yield-boosting solution using passive nanotech cooling — directly aligned with African agricultural challenges.
Why IOMTEK?
-
Enables local production of heat-sensitive crops (less import dependency)
-
Improves ROI per greenhouse m²
-
Reduces operational costs (no pesticides, no electric cooling)
-
Scalable from smallholders to corporate farms
