N2-Gen® TL Series –Transmission Line Pressurization™
The N2-GEN® TL Series – Nitrogen Generation Systems provide an infinite supply of 98%+ pure Nitrogen, ensuring a constant -10o to -50o F dew point within the transmission line. By freeing the environment of oxygen, moisture and contaminants, the N2-GEN® maintains the integrity of the transmission line and prevents voltage arcing failures. The N2-GEN® utilizes the only dual-bed Pressure Swing Adsorption (PSA) technology available on the market. This design is more efficient, less demanding of internal components, and lasts up to 50% longer than dry desiccant and membrane dehydrators. See below for more information regarding N2-GEN® TL Series models, resources and specifications.
