Alaqua Inc is the heat exchanger maker for all kinds of machines used by different industries for various purposes. The varieties of heat exchangers available are shell and tube heat exchangers; double pipe heat exchangers; plate heat exchangers; Condensers, evaporators, and boilers. Though the heat exchangers are different sizes as per the machine requirements, they all function under the same basic principles. The main features of heat exchangers are flow configuration, construction method, heat transfer mechanism. There are three types of heat exchanger that are conduction, convection, and radiation where conduction occurs in solids or fluids that are at rest, heat transfer is convection occurs in liquids or gases that are in motion, and radiation takes place with no material carrier.
