Freeze sprays, also known as "circuit chillers" or "circuit coolers," are a type of aerosol spray that are commonly used in various industries for a range of purposes. When sprayed, the liquid inside the canister rapidly evaporates, causing a sudden drop in temperature that can freeze surfaces or cool down components.Freeze sprays are often used in the electronics industry, particularly for testing and troubleshooting electrical components. When a technician needs to test a circuit board or identify a faulty component, they may use a freeze spray to rapidly cool down specific areas of the board to see if any changes occur. The sudden drop in temperature can cause certain components to contract or expand, which can help diagnose problems that may not be immediately visible.Additionally, freeze sprays are commonly for diagnosing engine problems. A technician may use a freeze spray to cool down specific areas of the engine to help identify potential issues, such as loose or worn parts.
