The RFT type of Alfa Laval (DeLaval) milk coolers is designed for smaller quantities of milk.
As the pictures reveal it is an "open" model, that is, in stead of just a manhole the lid covers
the entire top of the tank. RFT tanks have a capacity range of 200 to 1400 litres.
The table below shows all types, their capacity, and their measures.
