The overall heat transfer coefficiency of Borosilicate glass equipment compare favourably with many alternative materials because of its smooth surface which improve the film coefficient and reduce the tendency of fouling. Heat exchangers are avilable in two basic types: coil type and shell & tube type. Shell & tube type heat exchangers are of recent development.

Condenser are use for condensation of vapours and cooling of liquids. Condensers are made by fusing number of parallel in a glass shell . Coils are made in different diameters using tubes of different bores. The average co-efficient of heat transfer in coil condenser is considered as- Condensation 200 - 270 Kcal/m2, hr, ºC appx. Cooling 100 – 150 Kcal/m2, hr, ºC appx.
