Miniaturized Active Cooling Systems World's smallest vapor compression systems

Active cooling involves using energy-consuming systems, like a compressor based refrigeration system or thermoelectric devices, to lower temperatures below ambient levels. Active cooling is essential when passive methods (like heat sinks or natural convection) can’t maintain desired temperatures for high-powered or high-heat dissipating devices. When moving from passive to active cooling, space and power constraints are often the primary challenges. Aspen Systems has developed the world’s smallest, most energy efficient active cooling systems to solve these space and power challenges and make transitioning to active cooling as seamless as possible.

Aspen’s miniaturized compressors and refrigeration systems offer higher efficiency, smaller footprint, and greater cooling capacity than thermoelectric (Peltier) devices. While thermoelectric modules are compact, they often require larger heat sinks and fans, leading to overall increased size, noise, and power consumption. In contrast, Aspen’s miniaturized cooling systems provide more efficient heat transfer, reducing the need for bulky components.

Aspen Systems products are designed for space and power-constrained environments, offering:

• High cooling capacities from 100 W to 1400 W or more
• Compact footprints suitable for integration into portable devices
• Low noise levels
• Natural refrigerants with low Global Warming Potential (GWP)
• ISO 9001 registered USA manufacturer

These features make Aspen System products ideal for applications in aerospace, electronics, lasers, medical devices, military, semiconductor, and more.

Yes, Aspen offers tailored solutions to meet the unique thermal requirements of various industries. Aspen’s engineering team collaborates with OEMs to design systems that fit specific size, weight, and power (SWaP) constraints; they have extensive experience supporting customers from concept to prototype to pilot program and full scale, large volume production. Our base (standard) systems are often used as the starting point to deliver highly configured, customized cooling solutions.

Aspen prioritizes environmental responsibility by utilizing natural, low GWP refrigerants, such as R-290. We are continually monitoring EPA, EU, and global regulations and utilizing new refrigerants to meet the demands of both compliance and performance. This approach aligns with global sustainability goals and helps OEMs meet regulatory standards while maintaining high-performance cooling.
