Watts thermostatic mixing valves: • Maintain and limit mixed hot water to a desired, selectable temperature • Provide a way to control outlet temperatures to help mitigate the risk posed by unmonitored, untempered water

THE DEW POINT TEMPERATURE - Clearwest

The dew point temperature is the temperature to which the air must be cooled before dew or frost begins to form. The dew point temperature is also a measure of the amount of water vapor in the current air mass. The higher the dew point, the more water vapor there is in the air. Air holds water in various amounts in the invisible gas state .
