Act Heat Pipes Reach 1 Million Hours On-Orbit Milestone

lancaster, pennsylvania- april 10, 2013, advanced cooling technologies, inc. (act) (www.1-act.com) announced today that its constant conductance heat pipes (cchp’s) have successfully reached over 1 million total hours on-orbit, providing thermal management on-board numerous satellites.  recent launches onboard orbital sciences corporation-built (nyse: orb) intelsat 23, star one c3, mexsat bicentenario and azerspace/africasat-1a have pushed act’s flight heritage over this significant milestone.


“this is a significant milestone for our cchp flight heritage”, says john hartenstine, manager of act’s aerospace products group.  “we were excited with our first launch placing cchps into orbit in november, 2009.  since that time the aerospace products team has supplied over 400 heat pipes to the aerospace community for spacecraft integration, many of which are currently operating on-orbit.”

act’s aerospace products group consists of personnel having diverse engineering and technical skills, making the group capable of solving some of the most demanding thermal management problems in spacecraft and aircraft. the group’s customer-focused approach is driving rapid growth and allowing act to quickly become a trusted supplier of flight-quality products, advanced research and development, and thermal management consulting services for the aerospace industry.  the group’s satellite thermal control products include:

  • cchp, vchp, lhp
    • build-to-print, or custom designs
    • embedded and external mount
    • in-house and custom extrusions
    • 2d and 3d configurations
    • integration with radiators
    • aerospace qualified soldered assemblies
  • titanium struts
  • accumulators

the group also provides complete thermal and mechanical design and analysis services for spacecraft thermal control systems.
