Refrigeration systems present some of the toughest insulation challenges of any mechanical system. Supermarkets, beverage-dispensing lines, food processing, ice rinks, cold storage, etc., rely on insulation to prevent heat gain and control surface condensation, both of which put products and/or operations at risk.
Refrigeration applications encompass a variety of operating temperatures, piping materials, space and environmental conditions, refrigerants and fluids – all of which impact insulation selection.
Aeroflex is capable of meeting all these demands and conditions. The extremely low permeability and durability of EPDM foam makes it a reliable solution for these demanding applications. It is an effective, low-cost alternative to cellular glass, and easier to install.
Why non-polar EPDM elevates insulation preformance
Aeroflex's Aerocel brand of insulation products are unique among other closed-cell elastomeric foams in that they are classified “non-polar.” EPDM (Ethylene Propylene Diene Monomer) is a non-polar compound and the basis for all Aerocel insulation.
Polarity is a function of the electrical charge across a molecular structure. When a material is classified as “non-polar,” it means that the electrical charges are evenly distributed across each molecule. This makes the molecules more stable, especially when exposed to water. As a result, Aerocel insulation degrades at a slower rate than other closed-cell elastomeric brands, especially when exposed to moisture, sunlight, ozone and a wide range of temperatures.
Because Aerocel EPDM insulation is hydrophobic, meaning that it does not react with water, it is inherently microbial-resistant and lasts longer, providing owners with a more favorable product life-cycle assessment and cost than other closed-cell elastomeric foam insulations.
