Gas treatment and recovery GTRU-type units recover, purify and refill the SF6-gas with a high degree of safety and reliability during the process, offering versatility through an automated drive and control technology.

Through a high-performance efficient process our GTRU-type units dry, filter and liquefy SF6-gas to refill the internal tanks and external SF6-cylinders. As an additional feature, we offer the ability to recover and refill one gas compartment while simultaneously evacuating another.
