Coil Condensers are used for condensation of vapours and cooling of liquids. Condensers are made by fusing number of parallel coils 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, °C appx.
Cooling 100 – 150 Kcal/m2, hr, °C appx.
