Refrigeration

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.

Benefits:

Effectively retards heat gain/loss and prevents condensation and ice
Can contribute to EPA’s GreenChill certification
Fiber-free for healthier indoor environments
Naturally microbial resistant
Low Halogen content makes it safe to install on stainless steel, aluminum & copper piping
Prevents corrosion under insulation (CUI)
Non-polar – does not react with water
Lower material, fabrication & installation cost with less waste than cellular glass (Aerocel® Ultra-Low Perm ULP®)
Naturally UV-resistant for long lasting service
Fire safety – Passes ASTM E 84 25/50 up to 2” (50 mm) thick
Built-in vapor retarder eliminates the need for jacketing in typical applications
Complimentary components like Aerofix-U® insulated pipe supports, EPDM tapes, etc. provide an airtight hermetic seal throughout the insulated system

Aerocel REF

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.
