Aerocel® REF Refrigeration Tube Insulation


Aerocel REF closed-cell elastomeric piping insulation helps keep critical refrigeration systems up and running 24/7 with superior moisture resistance and condensation control.

A wide temperature operating range makes Aerocel REF suitable for most any refrigeration application. It is even able to withstand high temperature spikes from hot gas defrost cycles. A proprietary blend of EPDM rubber ensures durable and reliable insulating performance for the most demanding refrigerant piping applications.

Available in unslit and Stay-Seal® with Protape® (SSPT™) tubes, black and off-white colors, and in a wide range of sizes and thicknesses to meet energy code and condensation control requirements.
