Chinese manufacturer Refrigeration Unit Sight Glass. It’s a kind of instrument used to detect the water content in refrigerant. It’s main function is to determine whether the water content in the refrigerant exceeds the limit by observing the color change of the Refrigeration Unit Sight Glass. This instrument usually has an indicator that shows the water content and a corresponding warning signal to alert the user. When there is too much water in the refrigerant, it absorbs heat from the surrounding environment and causes the temperature to rise. Therefore, the use of a Refrigeration Unit Sight Glass can help the user to identify the problem and make adjustments in a timely manner.
The Refrigeration Unit Sight Glass is a very useful tool to effectively monitor the operation of the refrigeration system and provide timely warning information to ensure the normal operation of the equipment and the user's comfort experience.
