Alfa Laval provides a comprehensive range of plate heat exchangers of the
traditional type, featuring gaskets between the plates.

The conventional type of Alfa Laval plate heat exchangers uses heat transfer plates fitted with gaskets that seal off each channel from the next, and direct the fluids into alternate channels. This type of plate heat exchanger is used throughout industry as standard equipment for efficient heating, cooling, heat recovery, condensation and evaporation. Generally speaking, all of these Alfa Laval units are notable for:

how it works?

Basically, heat transfer technology involves bringing two substances at different temperatures close to each other so that one either heats or cools the other. The gasketed plate heat exchanger consists of a series of thin corrugated plates fitted with gaskets. The plates are then compressed together in a rigid frame to create an arrangement of parallel flow channels. The two fluids flow in alternate channels so there is a large surface area over which the transfer of heat energy from one fluid to the other can take place.

The channels are specially designed to induce maximum turbulence in both the fluid flows in order to make heat transfer as efficient as possible. The two different fluids normally enter and leave at the top and bottom of the heat exchanger, respectively. This is known as the counter-current flow principle. The gasketed design also makes it easy to separate the plates quickly when they need to be cleaned, for example. It also makes it easy to adjust capacity by simply adding or removing plates as and when required.
