The plate condenser consists of plates that are welded together in pairs to form a so-called plate set. The concept of a plate set leads to two different types of channels: a weld channel for condensing steam and a gasket seal channel for cooling water. This type of plate is specially designed for optimum condensation. It has an asymmetrical arrangement with a large gap on the steam side and a small gap on the cooling water side. This makes it possible to maintain a very low pressure drop at the steam end while maintaining a certain speed and turbulence on the cooling water side. This maximizes heat transfer efficiency and minimizes fouling.
