Frequently Asked Questions and Explanations
Why do you need a silencer?
A silencer is used when steam is blown into water to make hot water, and noise and vibration due to steam inflow are reduced. If the silencer is not used, extreme noise and vibration will occur.
What is the sound limit temperature of the silencer?
The sound limit temperature is the maximum temperature of hot water that can maintain the function of the silencer.
What causes noise when steam is blown into water? Also, what principle does the silencer suppress the noise?
When steam is blown directly into water, the steam condenses and creates a cavity, and when the surrounding hot water flows toward the cavity and collides, a large impact and noise are generated. The silencer emits steam from a small nozzle and smoothes the mixing with water to reduce noise.
