HEATING JACKET HAVING PITCH AND DRAIN HOLE

摘要

A heating unit and method for use in heating a canister containing a reductant, such as ammonia for use in an after-treatment device in an exhaust system, is disclosed. The heating unit or jacket includes two sections forming an interior chamber for receipt and heating of the canister. The pitch of the heating jacket can be adjusted for draining any condensation that may have accumulated in the jacket during use. The pitch of the heating jacket can be adjusted to coordinate with a drain hole, which may be located in one or both sections of the heating jacket.
