Different Reefers

A few different reefers spotted during November.  

Both RWLU 22R1 type reefers, these are fitted with Carrier units and a large single cool-room type door for domestic type operations, rather than shipping utilisation.

This CRXU reefer is an AER1 type, which is a 20ft+ size, similar to customer built Toll Tasmania reefers.  

This CRXU reefer looks to be the same but is an AERB type.  I can't tell the different externally, and they may actually do exactly the same thing.

Enjoy!
