The Whisper Valve is a silenced safety device for use with cryogenic containers. The valve solves the problem of the loud noise, over 100 dB, associated with the activation of the relief valve in cryogenic containers containing nitrogen, argon or carbon dioxide. Many users of gas in cryogenic containers complain to their suppliers that the loud activation noise scares their employees and causes work disruptions and results in damaged product. The Whisper Valve is easily installed on the vent valve of any cryogenic container and silently relieves the container pressure slightly below the normally installed relief valve. Whisper Valve reduces the relief of gas pressure to a noise level of 40-50 dB under normal conditions. For reference the average library noise level is 40 dB. The Whisper Valve also reduces the gas losses of your cryogenic container to average of less than 48 cubic feet over 24 hours. Whisper Valve 500 psig. Other settings available between 22 psig - 500 psig. |
