2 mm of Aerogel Insulation Cuts Reactor Surface Temperature in Half

Working conditions near reactor improve, energy consumption drops

Thermal imaging shows a safe surface touch temperature after Pyrogel 2250 is applied.

The 2 mm insulation thickness was the maximum that could be used given the space required to screw the bolts using a pneumatic gun.

An additional layer of EPDM rubber was applied to protect the insulation where the pneumatic gun was used.

The finished surface protects the insulation during standard operations with no metallic cladding required.

• Insulate the external part of a reactor that has a process temperature of 120°C (248°F).
• The insulation objectives were to:

1. Eliminate heat dispersion from the reactor into the
   surrounding room.
2. Allow operators to unscrew the bolts without removing or damaging the insulation.
3. Achieve a safe surface touch temperature minimum
   insulation thickness.
4. Provide a finished surface that didn’t require metallic cladding.
5. Allow mounting/dismounting operations without losing time.

Aerogel Solution

• Agosti Isolazioni Termiche installed an aerogel solution of 2 mm Pyrogel® 2250 using a specifically chosen adhesive that was tested prior to installation.
• The external surface was covered with layers of varnish that were tested prior to installation. The end user chose from seven colors for the external surface.

Benefits

• The end user observed a reduction by almost half of the external surface temperature with only a 2 mm insulation thickness.
• The insulation was applied directly on the reactor, saving valuable time during numerous mounting and dismounting of the reactor.
• The insulation noticeably improved operator working conditions near the reactor and reduced energy consumption significantly.
