Here is the mfg. You are looking for.
They make different combinations fridge/ fridge, fridge/ freezer, etc. Ours is only fridge so no freezer which we miss but like having 2x the space in fridge.
I dont have our model # handy but we like the unit, easy access, runs quiet.
One suggestion if doing the install is to add a fan to force vent the condenser space as it will help efficiency. The fridges have a set of contacts to run fan auto when unit operates. Pulling mine out & adding a muffin fan is on the To Do list but hasn't gotten to the top of the list.
