ACT’s Fluid Accumulators Delivered to the International Space Station

Lancaster, Pennsylvania– January 14, 2015. Advanced Cooling Technologies, Inc. (ACT) ( announced today four fluid compensation accumulators installed in NASA’s Cloud Aerosol Transport Systems (CATS) instrument were successfully delivered to the International Space Station (ISS) aboard SpaceX’s CRS 5 dragon capsule which docked with the space station on January 13th 2015.

The fully stainless steel accumulators provide volumetric compensation for fluid property changes across the broad temperature range experienced in spacecraft applications, from -40°C to 55°C. This new product was designed, manufactured, and qualified by ACT to operate for up to 3 years in this challenging environment. ACT introduced the accumulators in response to multiple requests for a rapid design and development supplier for custom, flight-qualified, fluid compensation systems.
