Shut Off Systems for Hazardous Gases Such as Trimethylamine
About Trimethylamine (TMA)
Trimethylamine is a colorless, flammable gas with a strong ammonia odor in high concentrations. It is used in agrochemicals, bactericides, catalysts, cation starches, feed additive, ion-exchange resins, pharmaceuticals, plant growth regulators, and surfactants.
Exposure to Trimethylamine is irritating to the skin, eye, and mucous membrane. Exposure to high concentrations of Trimethylamine or exposure over an extended period of time can lead to corneal damage.
Trimethylamine Valve Closure Systems (Shutdown Systems)
Powell Emergency Valve Closure Systems are designed to prevent significant releases of hazardous gases like Trimethylamine. In the case of an accidental release, the emergency valve closure system will close the valves in 10 seconds or less, effectively preventing further release from the container.
