Aspen Systems empowers engineers and organizations to build technologies that move the world forward with confidence and reliability.
We pioneered miniaturized cooling systems for military applications. Today, we deliver the world’s smallest, highest-capacity cooling solutions to customers and industries worldwide.
Read more about how we became the global leader in miniature cooling systems.
We design and manufacture miniaturized vapor-compression systems for active cooling that combines:
Optimized compressor based refrigeration packages engineered to maximize cooling power while minimizing footprint, weight, and power consumption.
We support air, liquid, and direct refrigerant based cooling systems tailored to your application requirements.
Our systems are built for integration into:
Designed and manufactured in Marlborough, Massachusetts with ISO 9001:2015 certified processes and strict quality control.
Our standard off-the-shelf systems often meet customer needs, but they also serve as the foundation for highly customized OEM solutions. Starting from these proven platforms allows Aspen Systems to efficiently tailor each cooling system to fit the exact performance, size, and integration requirements of the application.
Self-contained liquid cooling modules designed for integration into OEM systems requiring precise thermal control.
Ideal for:
LCMs provide reliable, closed-loop cooling in compact form factors with scalable configurations to match system requirements.
