On 22 September 2018, a Japanese H-IIB rocket launched the HTV supply vessel containing the ACLS (Advanced Closed Loop System) module destined for the International Space Station (ISS). The ACLS is tasked with “recycling” CO2 from the air in the spacecraft and generating fresh oxygen for the crew by means of electrolysis. KELLER has developed and manufactured highly reliable absolute and differential pressure transmitters to regulate these processes.
