Simplex Internal 

 Tube Heaters and Coolers 



And other . things must in- 

 terest you. ' 

 '• The Internal Tube System 

 does away with the danger 

 of contamination from out- 

 side sources. 



The Internal Tube System 

 saves loss from evaporation 

 as the milk during both the 

 heating and cooling processes 

 is not subject to atmospheric 

 conditions. 



The Internal Tube System 

 gives the greatest efficiency 

 in heating and cooling as the 

 sections can be connected up 

 on the regenerative principle. 



The Internal Tube System 

 is sanitary to the last degree 

 as every inch can be thor- 

 oughly brushed and then 

 sterilized with live steam. 



The Internal Tube System 

 requires less floor space per 

 thousand pounds of milk 

 than any other system yet 

 devised. 



The Internal Tube System 

 will bear the closest investi- 

 gation if you are building a 

 new or remodeling an old 

 plant.
