The forces during centrifugation may cause leakage around the top of the tube and cap because snap cap tubes are not completely airtight.
When it comes to small commercial refrigeration applications like prep tables and reach-in cooler boxes, capillary tubes are a fixed metering device that is frequently used. The process of turning the high pressure liquid refrigerant into a spray of low pressure liquid only requires a short piece of copper tubing.
Products that have already been chilled are stored using cap tube systems. It may take up to 24 hours for a cap tube refrigeration system to cool a box of non-refrigerated goods to the proper temperature.
A device used to metre refrigerant from a liquid state to a gas state is known as a refrigeration cap tube, also known as refrigeration capillary tubing.
