Controlling condensation and moisture on refrigeration cold-water lines is essential for long-term thermal performance. If moisture intrudes the insulating material surrounding cold-water piping, efficiency is lost. If the temperature surrounding the piping drops below the dew point, condensation will form on the pipes. The presence of moisture not only robs the system of its thermal efficiency, it also provides a suitable condition for mold and mildew growth and corrosion under insulation. Selecting closed-cell AP/ArmaFlex insulation is one sure way to prevent moisture (and therefore heat gain) from invading a refrigerated pipe system. Closed-cell elastomeric foam insulation exhibits a low permeability rating as well so it is much less vulnerable to punctures and tears that can impair the thermal effectiveness compared to open-cell and fibrous materials.
Supermarket refrigerators, freezers, and walk-in coolers operate 24 hours a day, whether the store is open or not. While energy costs are only about 2% of a supermarket’s revenue, 56% of a supermarket’s total electricity load is refrigeration. The EPA estimates a 10% reduction in energy usage is equivalent to increasing net profit margins by 16%. One way to capture significant energy savings is choosing the right insulation system for refrigerant lines. ArmaFlex has a low thermal conductivity which provides efficiency for thermal protection and energy savings. Its flexible nature and self-sealing options make it a great choice for easier installation, as well as helping to keep systems running at optimal temperatures with reduced energy costs.
Specifying for Value
Refrigeration systems need to function at top performance to attain the energy-efficiency that they need, which means they require the proper insulation. Our insulation systems are ideal for insulating miles of liquid and suction lines, chilled water piping, chillers and cooling tanks. Specifying Armacell insulation products from our Supermarket Solutions Portfolio is the best choice for several reasons. Offering two package levels each tailored to code compliance, system performance, and budget, make specifying the right insulation easier. Our products are always fiber-free, formaldehyde-free and GreenGuard certified for low VOC making them an excellent option for any environment, eliminating particulate that can jeopardize air quality and equipment. ArmaFlex preformed pipe insulation comes in many sizes and thicknesses from 3/8” to 2” and ArmaFlex sheet and roll insulation in thicknesses from 3/8” to 2” to accommodate diverse climate temperatures and humidity levels, making it an excellent choice for sustainable systems around the world.
