Boilers
Product Details :
Type HEB 100, HEB 150 and HEB glass coil type boilers are normally mounted in external circulatory loops using a spherical vessel as the main still. They should not be. installed in the bottom of a flask or column.
The other types of glass coil-type boilers detailed on this page are again mounted in circulatory loops but as their nominal bore is the same at the top and bottom. These units can, under certain circumstances, be installed one above the other to achieve multiples of the basic heat transfer area.
