Construction characteristics
The Pharmastill MS-E is composed of a first column provided with electrical heaters. Pure steam is generated in this column, and sent to the second effect, which is a standard column of the “steam heated” Pharmastill; here pure steam condensates on the shell side of the condenser, with consequent additional evaporation of feed water pipe side – as in the standard Pharmastill.
The installation of a suitable number of columns is suggested in order to minimize the installed electric power.
Stilmas has developed Pharmastill MS-E with up to 6 columns even for limited capacities (from 100 l/h), in order to grant the best energy efficiency, which is of outstanding importance in case of electrical feeding.
