What kind of insulation is typically required for high-temperature refrigerant lines?

Closed-cell insulation is typically required for high-temperature refrigerant lines because it provides superior thermal resistance and moisture control. This type of insulation is composed of cells that are completely closed, which prevents moisture from being absorbed. Since high-temperature refrigerant lines can experience significant temperature fluctuations, closed-cell insulation effectively retains thermal energy and prevents condensation that could lead to inefficiency or even damage over time.

Moreover, the structure of closed-cell insulation allows it to maintain its insulating properties under elevated temperatures, which is crucial for refrigerant lines operating in high-temperature conditions. The insulation's ability to resist moisture ingress further enhances its performance, protecting the integrity of the refrigeration system. Thus, for situations involving high-temperature refrigerant lines, closed-cell insulation is a reliable choice to ensure efficient operation and longevity of the system.
