Eternaloc®
Eternaloc® feedthroughs enable the transmission of electrical power and signals into and out of vacuum-tight assemblies. They provide long-term peace of mind for energy applications in challenging environments, including liquefied natural gas, compressed gas, nuclear power, submarines, and oil and gas equipment.
Safe and proven technology for energy applications
Eternaloc® feedthroughs and connectors protect safety-critical electrical infrastructure. This is especially important in potential severe accident scenarios that can include extreme temperature, pressure, thermal cycling, and shocks / vibration. SCHOTT’s unique compression glass-to-metal sealing has a proven track record and is seen as the safest technology available.
Maintenance-free reliability reduces cost of ownership
Our electrical feedthroughs have delivered maintenance-free performance for decades, enabling reduced recalls and replacements, as well as lower total cost of ownership. This means both safer and more cost-efficient generation and transportation of energy.
Superior robustness and performance for challenging energy applications
Eternaloc® feedthroughs represent a proven worldwide standard for the transmission of electrical power and data in a variety of safety-critical, harsh-environment applications. The components simultaneously act as gas diffusion-proof isolation elements.
