         7 . The container according to  claim 6 , wherein power draft of the one or more fan motors are monitored and an increase in power draft imply that the heating elements are following activated. 
     
     
         8 . The container according to  claim 1 , wherein the fan or fans are arranged together with a motor in a unit for removal or exchange during maintenance. 
     
     
         9 . A method for loading a reefer container with pallets, wherein at least eleven pallets of ISO 2 type or fourteen pallets of ISO 1 type are placed in the container ( 14 ) with a longitudinal direction of the pallets going in a direction crosswise in relation to a longitudinal direction of the container and at least ten pallets of ISO 2 type or ten pallets of ISO 1 type are placed in the container with the longitudinal direction of the pallets going in a direction parallel with the longitudinal direction the container. 
     
     
         10 . The method according to  claim 9 , wherein the pallets of ISO 2 type are placed in two rows within the container, a first row comprising nine pallets placed in the container with a longitudinal direction of the pallets going in a direction crosswise in relation to a longitudinal direction of the container and two pallets placed in the container with the longitudinal direction of the pallets going in a direction parallel with the longitudinal direction the container and a second row comprising eight pallets placed in the container with the longitudinal direction of the pallets going in a direction parallel with the longitudinal direction the container and two pallets placed in the container with a longitudinal direction of the pallets going in a direction crosswise in relation to a longitudinal direction of the container. 
     
     
         11 . The container according to  claim 2 , wherein one or more fans are placed in one or more ducts, which ducts leads from the evaporator and further leading the cooled air into cargo space of the container. 
     
     
         12 . The container according to  claim 2 , wherein the fan or fans are powered by permanent magnet motors. 
     
     
         13 . The container according to  claim 3 , wherein the fan or fans are powered by permanent magnet motors. 
     
     
         14 . The container according to  claim 2 , wherein a protruding surface and an edge forming a trap for trapping liquid or ice is provided above the one or more fans. 
     
     
         15 . The container according to  claim 3 , wherein a protruding surface and an edge forming a trap for trapping liquid or ice is provided above the one or more fans. 
     
     
         16 . The container according to  claim 5 , wherein a protruding surface and an edge forming a trap for trapping liquid or ice is provided above the one or more fans.
