Zero Grid. 16-Hour Autonomy. 1°C Stability.
This 35m³ cold storage room in Shanghai is a live demonstration of just one application for Sun-Ice Energy’s active thermal architecture.
The logic is simple, but the performance is industry-leading:
Daytime: Solar simultaneously cools the room and charges the thermal battery.
Nighttime: For 16 hours after the sun goes down, the thermal ice wall takes over, maintaining precision stability with zero grid reliance.
The Net Effect:
Asset Longevity: By reducing mechanical strain, we extend chiller lifespan by 10 to 15 years minimum.
Rapid ROI: We are seeing a 3-year ROI in China—and sub 1-year in markets like Germany based on grid electricity prices alone.
Next Milestone: Proving the same autonomous stability at 0°C (32°F).
From industrial cooling to climate-positive architecture, we are proving that high-performance infrastructure doesn't need a footprint. It just needs better physics
