Heat exchangers

A heat exchanger is a device that transfers heat from one medium (liquid, gas) to another medium. An ideal heat exchanger cools the first medium to the temperature at which the second started and vice-versa. The counter-flow principle can be used in an effort to achieve this ideal. A few types of
construction are: tube heat exchanger, plate heat exchanger, spiral heat exchanger.
The exchangers are manufactured by certified welders in accordance with the EN287-1, AD Merkblatt or ASME. The example shows a block spiral in operation.
