Tractor Oil Tank Protected by
Aerogel Heat Shield in Tight Space

Insulation maintains high performance even in exposed environment

Carpenter designed a solution of two layers of Spaceloft™ 6251 encapsulated in aluminum (shown above), with a total thickness of only 16 mm. The encapsulated aerogel solution was glued on the tank with a viscoelastic mastic (below).

• Develop heat shield for the PE rotomolded oil tank of a tractor.
• The oil tank was located near the tractor exhaust, with the air outtake pointed at the tank.
• There was a high risk of deformation and failure of the oil tank.
• Traditional solutions such as glass or rock fiber were too thick given the space constraint.
• The temperature was 200°C (392°F) at the exhaust outtake and 120°C (248°F) at the tank surface (30 mm away).
• To maintain low tank temperature, exceptional thermal performance in a limited space was required.

Aerogel Solution

• Carpenter designed a solution of two layers of Spaceloft™ 6251 encapsulated in aluminum.
• The total thickness was only 16 mm.
• The encapsulated aerogel solution was glued on the tank with a viscoelastic mastic.

Benefits

• Spaceloft 6251 maintained its performance over time, reducing the surface temperature of the tank to 85°C (185°F) after 1 hour 15 minutes and stabilizing it at 95°C (203°F) after 2 hours 20 minutes.
• The encapsulated aerogel solution was unaffected by the outside environment including high pressure washing of the engine.
