Application
Most processes include a stage in which a product is either cooled or heated, or both, through several heat transfer sections, for example in a pasteurisation process. This can be achieved with the help of plate heat exchangers. They are used in the food (dairy, beverage, beer, etc.), wine, chemical and pharmaceutical industries among others.
Our heat exchangers are extremely versatile: by means of a simple modification in the number of plates, they can be adjusted according to changes in the product flow capacity or changes in the application operating temperature.
Operating principle
The plates provide the heat exchange surface required for the process. Each plate and gasket set, create a closed system of alternating parallel passages between the plates, where the main fluid circulates through one side and the heating or cooling medium circulates through the other, allowing the heat exchange between both fluids. For better heat transfer, the fluids flow in opposite directions (counter current).
Design and features
Plate heat exchangers consist of a series of stainless steel (or other material) plates mounted in a frame and supported by a carrying bar at the top and a guide bar at the bottom. The frame is made up of a fixed end and a movable end, and is compressed by means of tightening bolts.
The plates are made of stainless steel and designed to achieve a perfect distribution of the product over the whole of the heat transfer surface. Mechanically fixed gaskets are used to obtain a perfect separation and spacing between the plates.
Depending on the heat exchanger model, the frame material can be AISI 304 stainless steel (models I7, I9 and I26), or painted carbon steel (model I13).
