Product Description

Coil type heat exchangers are mainly used as condensers, coolers, or re-boilers, apart from the general heat transfer function between two fluids at different temperatures. It is usually made of two components an outer jacket and an inner coil battery, which are welded together to make a one piece unit.

Coil type condensers are used for condensation of vapours and cooling of liquids. These are made by fusing a number of parallel coils in a glass shell. Coils are made in different concentric diameters using tubes of different nominal bores.

Usually, the coolant flows through the coils while the vapour flows through the jacket. Condensers with heat transfer area (HTA) up to 8m2 are readily available. Usually, it is accompanied by a reflux divider to ensure complete collection of the distillate.

Coil type heat exchanger are more efficient than shell and tube exchangers for low flow rates. It is clean both inside and outside with no caustic stains. Due to their simple construction they are low in price and easy to clean on the shell side. Their thermal efficiency approximates that of a true counter current flow type exchanger. 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.


Advantages:
The electrical properties of copper are exploited in copper wires and devices such as electromagnets.
Integrated circuits and printed circuit boards increasingly feature copper in place of aluminium because of its superior electrical conductivity (see Copper interconnect for main article)
Heat sinks and heat exchangers use copper as a result of its superior heat dissipation capacity to aluminium. Vacuum tubes, cathode ray tubes.
The magnetrons in microwave ovens use copper, as do wave guides for microwave radiation.
Copper’s greater conductivity versus other metallic materials enhances the electrical energy efficiency of motors.
