Nighttime Cold Storage Cooling Solutions

Our Nighttime Cold Storage Solution utilizes off-peak electricity and low nighttime ambient temperatures to pre-cool systems, store thermal energy, and reduce daytime load on mechanical cooling systems. By combining high-efficiency evaporator coils, dry coolers, and thermal storage media, this approach helps data centers optimize power usage, cut cooling costs, and increase overall energy efficiency without modifying server infrastructure.
Engineered for integration with existing HVAC, chilled water loops, and coil-based cooling systems, this solution supports both traditional and next-gen data center builds.

Core Advantages

Designed for Immersion Heat Rejection

Use high-performance condenser coils and dry coolers to transfer heat from dielectric fluids to outdoor air or secondary loops with maximum efficiency.

Silent, Passive Cooling

Fanless or low-noise dry coolers eliminate mechanical noise common in traditional HVAC systems, supporting the silent operation of immersion-cooled data centers.

Optimized Coil Configuration

Coils designed with enhanced surface area, fin spacing, and loop layout to match immersion tank load profiles and fluid temperature ranges.

Scalable for High Density

Supports cooling demands of high-density immersion tanks (AI, GPU clusters) with customizable heat rejection capacity.

Typical Application Scenarios

GPU & AI Clusters in Immersion Tanks

  • Use evaporator coils and condenser coils to reject heat from dielectric coolant circuits to air or water-based secondary loops.

Two-Phase Immersion Cooling Systems

  • Support vapor condensation using custom condenser coils inside sealed enclosures or integrated with external dry coolers.

Edge Data Centers with Limited Cooling Infrastructure

  • Compact dry coolers offer reliable outdoor heat rejection for immersion systems where mechanical chillers are impractical.

Modular Containerized Data Centers

  • Coil-based heat transfer systems simplify integration and cooling for immersion-cooled containers in remote or grid-sensitive sites.
