Refrigeration Insulation Specification - Armacell1.3.1 All refrigerant copper lines must be free of extraneous chemicals such as corrosive cleaners or building materials' dust prior to the installation of the insulation. The insulation must be clean and dry prior to installation. 1.3.2 Refrigerant pipe shall be sealed while slipping on insulation to prevent foreign matter from entering the ...
Types of Insulation for Refrigeration Applications ...Typically, 3 inches of insulation is used to prevent condensation, as many of these applications are in high-humidity areas. Ammonia refrigeration applications are demanding, and performance and longevity expectations are high. The majority of the insulation is installed outdoors, so jacketing selection is critical.
insulation - Should I insulate air conditioner coolant pipes ...This makes the refrigerant very hot. Then the refrigerant is run through the condenser coils and the fan blows outside air over them to remove the heat and condense the refrigerant back to liquid. The small line now carries the warm liquid refrigerant back into the house. No insulation is needed on this line because it is still warmer than the ...

Armacell: RefrigerationCarefully selected piping insulation is critical to the efficiency of a refrigeration system. Controlling condensation and moisture on refrigeration cold-water lines is essential for long-term thermal performance.
What is the purpose of Refrigerant Piping Insulation?Liquid lines generally are insulated. They are warm to hot (110°F (43.3°C) for air-cooled). If liquid lines pass through a space that is warmer than the refrigerant (i.e. the roof of a building at roof level), or if they could be considered hot enough to pose a safety risk, then insulation should be added.
