A system comprises an outer housing, an inner housing, a first seal and a second seal. The outer housing comprises an inlet and an outlet. The inner housing is mounted inside the outer housing. The inner housing is dimensioned relative to the outer housing to allow for an annular space between the outer housing and the inner housing. The first seal and the second seal are mounted in the annular space so as to define a fluid chamber enclosed by the outer housing, the inner housing, the first seal and the second seal. The inlet and the outlet are in communication with the fluid chamber. |
