  • 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.
  • 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.
  • 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.
