We installed it easily during short downtime thanks to the magnetic sheet design. Temperatures around key components fell, boosting efficiency, and low install cost allowed for a quick ROI.
SPACECOOL™ Radiative Cooling Material (PDRC)
Reduce thermal risk without increasing energy use. SPACECOOL™ is an advanced passive daytime radiative cooling (PDRC) material engineered to cool equipment below ambient temperature, even in direct sunlight. Its unique optical structure combines ultra-high solar reflectance and strong mid-infrared emissivity to passively emit heat through the atmospheric window—achieving true radiative cooling with no electricity, fans or moving parts.
Common Thermal Pain Points in Outdoor Equipment
Equipment Failure
Heat accelerates degradation of internal electronics, leading to instability, faults, or premature failure.
Measurement Error
Temperature fluctuations cause drift in sensors and instruments, compromising measurement accuracy.
CO₂ Emissions
Active cooling systems rely on electricity, contributing to higher energy consumption and increased CO2 output.
What Is SPACECOOL?
SPACECOOL is a next-generation PDRC (Passive Daytime Radiative Cooling) material that lowers temperatures 2–6°C below the surrounding air without any energy consumption.. It achieves advanced PDRC performance by combining:
- Ultra-high solar reflectance to minimize heat absorption (0.3–2.5 μm), and
- Strong thermal emissivity in the 8–13 µm atmospheric window, enabling efficient radiative heat loss to the sky.
This passive, maintenance-free cooling technology reduces heat stress and significantly improves the reliability of outdoor electronics and systems—without electricity,
Refrigerants or mechanical cooling devices.
Ultra-high solar reflectance (~95%) and high mid-IRstrong emissivity in the 8–13 µm atmospheric window for maximum PDRC efficiency.
Designed for real-world outdoor environments, SPACECOOL provides 10–15 years of stable radiative-cooling performance.
Magnet-sheet configuration enables tool-less installation and simplified maintenance.
SPACECOOL can reduce surface temperatures by 2–6°C below ambient under direct summer sunlight. Its radiative cooling capacity is 120–150 W/m², depending on weather conditions and internal heat load.
*Actual performance may vary based on environmental factors and equipment usage.
Comparison to Conventional White Paint & Reflective Coatings
Traditional White Paint & Reflective Coatings
(Conventional reflective coatings not true PDRC materials)
Reflect sunlight but do not release their own heat effectively.
High reflectance, low emissivity → heat becomes trapped.
Cooling stops at ambient air temperature; cannot achieve sub-ambient cooling.
SPACECOOL Radiative Cooling
(Reflective + high-emissivity + wavelength-selective design)
SPACECOOL was engineered to do both: keep sunlight out and send heat out. Its structure reflects almost all solar radiation and emits infrared heat through a natural atmospheric window. Using wavelength-selective optics it achieves: high reflectance of solar radiation (0.3–2.5 μm) and high emissivity in the atmospheric window (8–13 μm).
Consistent sub-ambient cooling, even under sunlight, with zero energy.
