We offer custom-designed and manufactured solutions optimized to meet our partners’ specific requirements in relatively low production volumes from low hundreds to low thousands of units per year at reasonable prices.


Based on our own in-house developed, variable speed, miniature compressors, we provide the smallest packaged cooling solutions with the highest cooling capacity possible allowing our partners to easily integrate our thermal solutions into small spaces inside their console, chassis, or device.


With tens of thousands of cooling units in service worldwide from MedTech to military applications, our products have proven durability. Aspen’s ISO 9001:2015 Quality Management System ensures highly reliable systems with less maintenance and fewer service calls.


Aspen’s products, with a high efficiency, variable speed, brushless DC motor compressor, have demonstrated higher efficiency than any other compact thermal solution on the market. Thermoelectric-based systems consume up to 5 times more power than Aspen’s products.


While our thermal systems are small, often less than a shoebox, our cooling capacity is not. Powered by our own variable speed miniature compressor, our compact systems produce cooling capacity greater than systems ten times their size. You cannot find this level of cooling in this size package anywhere else.



Medical equipment designers and manufacturers must keep the equipment size, noise, and power consumption minimized while incorporating thermal management systems. Aspen Systems has been developing and manufacturing cooling systems for medical equipment for many years that are compact for direct integration into the console yet provide powerful levels of cooling while operating at high efficiency to reduce heat rejection in the operating room, clinic, or doctor’s office.

Life Science

Applications such as blood analysis and DNA decoding require compact, accurate, and reliable cooling systems to meet the demands of laboratory instruments. The Aspen Systems product development team has worked closely with multiple customers to develop vapor compression cooling systems that are efficient, accurate, quiet, and reliable to meet the demands of laboratory and life science applications while being compact for easy integration within our customer’s devices.


Laser product managers are seeing similar pressure to reduce the size of the external laser chiller while still offering improved cooling and energy efficiency. Some are considering adding the refrigeration system directly into their laser system to form an integrated compact package. It is important to make decisions early in the concept development of the product development cycle to ease the integration of advanced cooling methods such as direct refrigerant cooling.


It is no secret that electronics packaging and semiconductors have gotten smaller, while their heat dissipation has gotten greater over the last decade. Aspen’s product development team is using advanced techniques to meet the requirements of both testing and IC cooling.


Military vehicles are designed to operate in extreme conditions including a large range of ambient temperatures, as well as shock, vibration, blowing sand, and driving rain, to name a few. This leads to the requirement for thermal management systems that can not only handle the heating and cooling needs of the electronics but must also be designed to survive the aforementioned environmental challenges. Aspen has a long track record of successfully developing and manufacturing thermal management systems for a range of military applications.

Electric Vehicles

The growth of Electric Vehicles (EV) ushers in a need for novel thermal management solutions. Heat loads driven by ever-increasing and higher energy densities in battery technology, electronics, and rapid charging require high-efficiency cooling systems in compact packages.
