Check out this introduction to heat exchangers made by the American Petroleum Institute.  This is a good basic primer to understand how heat exchangers work in an industrial plant.  Ameritube produces copper alloys heat exchanger tube in C70600, C71500, C12200, C44300, Monel and other alloys.  Ameritube also distributes duplex, super duplex, stainless and carbon steel for these same applications, including nickel alloys such as Monel 400, Nickel 200, and C-276.  Below you can find additional heat exchanger pictures where Ameritube tubing was installed.

A heat exchanger is a device used to transfer. Heat exchangers using copper and its alloys have evolved along with heat transfer technologies over the past several hundred years. Copper condenser tubes were first used in 1769 for steam engines. Initially, the tubes were made of unalloyed copper. By 1870, Muntz metal, a 60% Cu-40% Zn brass alloy, was used for condensers in seawater cooling. Admiralty metal, a 70% Cu-30% Zn yellow brass alloy with 1% tin added to improve corrosion resistance, was introduced in 1890 for seawater service.[2] By the 1920s, a 70% Cu-30% Ni alloy was developed for naval condensers. Soon afterwards, a 2% manganese and 2% iron copper alloy was introduced for better erosion resistance. A 90% Cu-10% Ni alloy first became available in the 1950s, initially for seawater piping. This alloy is now the most widely used copper-nickel alloy in marine heat exchangers.

Today, steam, evaporator, and condenser coils are made from copper and copper alloys. These heat exchangers are used in air conditioning and refrigeration systems, industrial and central heating and cooling systems, radiators, hot water tanks, and under-floor heating systems.

Copper-based heat exchangers can be manufactured with copper tube/aluminium fin, cupro-nickel, or all-copper constructions. Various coatings can be applied to enhance corrosion resistance of the tubes and fins.

Heat exchangers are devices that transfer heat in order to achieve desired heating or cooling. An important design aspect of heat exchanger technology is the selection of appropriate materials to conduct and transfer heat fast and efficiently.
