Aerocel® REF Refrigeration 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 is to thank for its versatility, super low permeability and overall durability.

Aerocel REF is available in solid tube and pre-slit tube with Aeroflex’s SSPT dual tape seam closure.
