Miniature Pumped Loop

APR Technologies presents the miniature pumped loop, an active thermal control solution for spacecrafts.

The miniature pumped loop is a patented liquid based thermal regulation system. The “no-moving-parts” thermal regulator system enables variable conductance and/or the possibility to efficiently transfer heat from one medium to another.

  • Small-size , low mass and low power consumption
  • Minimum vibrations, wide temperature range, and on/off functionality or precision regulation to ±0.1 K.
  • For space applications it overcomes the gravity head problems allowing efficient and correct AIT cycles.
  • ITAR free

Micro Pumped Loop

APR Technologies presents the micro pumped loop, an active thermal control solution especially suitable for micro and nano spacecrafts.

The micro pumped loop is a patented liquid based thermal regulation system. The “no-moving-parts” thermal regulator system enables variable conductance and/or the possibility to efficiently transfer heat from one medium to another.

  • Extremely small size, low mass and low power consumption.
  • Minimum vibrations, wide temperature range, and on/off functionality or precision regulation to ±0.1K.
  • For space applications it overcomes gravity head issues and allows on-ground testing for the space industry.
  • ITAR free
