Shawn put his production team up against the “stay at home gang” to see who could raise more money. While the competition got heated, the senior management at Aspen Systems stepped in to offer dollar for dollar matching of each employee’s donation to the food charity of their choice. Contributions were made to local food banks as well as national and international food charities. As a result of Shawn’s challenge the Aspen team donated over $15,000!

About Hunger
Over 50 million Americans and 690 million people worldwide struggle with food insecurity. By the end of the year 12,000 people per day could die from hunger linked to COVID-19, potentially more than will die from the disease itself. The COVID-19 pandemic has placed enormous pressure on the global food supply chain. The United Nations Food and Agricultural Organization (FAO) warned of “a looming food crisis,” stating that the pandemic could have a devastating impact on global hunger and poverty – especially on the poorest and most vulnerable populations. Global poverty is projected to increase for the first time since 1998, reversing decades of global progress against hunger and malnutrition.

If you want to donate, here are a couple of organizations to consider: The Feeding America network provides over 4.3 billion meals annually, helping 1 in 7 Americans facing hunger live more secure and stable lives. Active in 45+ countries and for more than 40 years, Action Against Hunger have led the global movement that aims to end life-threatening hunger for good within our lifetimes

Aspen Expands Space by 50%

Aspen Systems acquires additional 6,000 sq ft of space in response to rapid growth of orders

Marlborough, MA – Aspen Systems, an innovator in ultra-compact refrigeration systems has added 6,000 square feet of space to accommodate additional production lines, offices and inventory fueled by their rapid growth.  According to James Burnett, Director of Business Development, “Our recent growth has been driven by a substantial uptick in orders from our existing customers in medical esthetics, lasers, semiconductor, and electronics.  We have also seen substantially increasing business from emerging markets such as electric vehicle, energy storage and biomedical.” 


Aspen Systems was founded in 1984 by Dr. Kang Lee as an R&D firm, primarily to address the needs of the U.S. Government.  Initial funding was secured through numerous successful proposals to the Department of Energy (DOE) and Department of Defense (DOD).  One initial achievement was the development of an economical way to manufacture a super insulator, Aerogel, which was spun out into a $100M+ publicly traded company.  Based on the needs of the U.S. Army and through support from the Small Business Innovative Research (SBIR) program, Aspen developed the world’s smallest rotary compressor.  The miniature compressor was first used in an air conditioning unit cooling military electronics on the WIN-T, and MRAP, and JLTV programs. 


Dr. Lee noted, “The combination of extremely small, high efficiency and low weight made the Environmental Control Unit (ECU) vital for mobile applications.  More than 3,000 systems logging millions of hours of operation were used in both Afghanistan and Iraq, without a single compressor failure.” The uses for the miniature cooling systems have continued to expand, with the commercialization of their novel technology resulting in applications for thermal testing of integrated circuits, cooling in medical aesthetics, and laser cooling in medical devices and industrial applications.

Cooling of High Power Charging (HPC) Stations for EV

With growing concerns about fossil fuels and their impact on global warming, Electric Vehicles (EV) are seeing a major surge in production in China, Europe, Japan and the United States.  According to the International Energy Agency, electric vehicles will grow from just over three million today to 125 million by 2030.  Conventional charging with alternating current can take up to eight hours.  Charging stations have rapidly switched to high power, rapid EV chargers using direct current that can recharge batteries as quickly as ten minutes on the charging station.

These High Power Charging (HPC) stations generate high currents, up to 500 Amps at 1,000 Volts requiring the electrical charging cable and connector to be cooled.  Aspen Systems, a pioneer in ultra-compact refrigeration systems is providing novel solutions for EV charging station manufacturers and is shipping hundreds of cooling systems per month as part of this effort. 

The state-of-the-art benefits Aspen provides this expanding application include:

  1. Rapidly developed custom systems
  2. Compact size, low weight
  3. Efficiency
  4. Flexible design
  5. Reliability and operation in extreme environments

As part of a U.S. Department of Defense project, Aspen Systems developed the world’s smallest rotary compressor which forms the enabling technology required for use in applications with extreme space or weight constraints.  Typically, for EV charging stations, a chilled liquid flows around the cable and connector for efficient heat dissipation.  The chilled liquid can also be used to cool any other heat generating components within the station.  Aspen works closely with the customers’ engineers to ensure a design that can be integrated directly into the unit and provide the requisite cooling power.

For instance, one major manufacturer needed an active thermal management solution to fit into one of their existing enclosures.  The space constraints (narrow and tall) prevented a standard Aspen module to be integrated.  Aspen’s experts in refrigeration and cooling, successfully designed a new chiller layout using primarily available components (evaporator, condenser, etc.) to fit the space, while also designing ease of access for maintenance.

Stated by the buyer:

“Your unit is a remarkable device.  High performance in a very compact package.  Our engineering teams are very much a fan (no pun intended).  That remarkability, that performance and that packaging is why we will continue to look at your products.”

Vapor compression refrigeration offers the highest efficiency in refrigeration.  Compared to thermoelectric or Peltier cooling, vapor compression provides three to five times superior efficiency.  Reliability in extreme environments is a key consideration for manufacturers of EV charging stations.  Over 3,000 of Aspen Systems’ cooling systems have been deployed by the US Military in Afghanistan and Iraq.  These systems have logged millions of hours of operation cooling mobile communication electronics enclosures used in Humvees and Mine-Resistant Ambush Protected (MRAP) vehicles.  Uninterrupted communication is vital to front line forces. Not a single compressor failure was seen–even though exposed to the harsh heat and cold of the desert and the vibration imposed in a military vehicle.

According to Glenn Deming, Vice President of Aspen Systems, “Many of the same reasons the Department of Defense selected Aspen Systems for their mission critical application apply to the design needs of EV station engineers – small size, efficiency and rock solid reliability”.

Brief History of EV

Although Electric Vehicles (EV) are not new, they are seeing exponential growth with advances in battery and battery-charging technology.  The first EV’s were demonstrated all the way back in the 1830s, and in 1902, the Studebaker Automotive Company was the first to offer mass produced vehicles.  However, limitations in the storage batteries prevented widespread use because of limited range between charges.
