Neon purification system purifies neon gas by, first purging air with CO2, freezing the CO2, then cryoadsorbing the remaining contaminants. The freezer removes carbon dioxide from a neon gas mixture down to a maximum concentration of 500 parts-per-million (ppm). The charcoal bed adsorber removes nitrogen from neon gas down to a maximum concentration of 100 ppm.
Neoprene hangers consist of a steel frame containing a neoprene isolation element. This element is molded with a rod isolation bushing that passes through the hanger frame. It is used for bolting or attaching to the ceiling flat iron straps, wires, rods and steel runners. It is used to reducing noise and minor vibration transmission. Hangers are noise breaks for use with wire, chain or horizontal screws for hung ceiling applications.
