Double wall plate heat exchanger principle
The double wall plate heat exchanger plate is welded integrally with two thin plate pieces along the corner hole of each pair of plates. When the plate leaks, for example, the perforation caused by long time working will be easily detected from outside. Thereby it stops mixing between two materials.And at the same time, they plays very important roles towards warning internal leakage. Combined with the double seal of the gasket, the possibility of mixing two materials is avoided, and it is suitable for applications with high sanitary requirements or high safety and reliability of industrial production. Since the two sheets are welded to form a sheet, the heat transfer coefficient is inevitably lowered, but the highest safety is achieved in preventing materials mixing.More +

Semi welded plate condenser
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.More +

Semi welded plate evaporator
Qingdao Ruipute plate evaporator is welded with a special corrugated pair of plates to produce high intensity turbulence, which greatly improves the heat transfer coefficient. The increase in heat transfer efficiency means a reduction in the required heat exchange area, which greatly saves investment costs, especially when special materials are required. The plate evaporator is compact and economical, so it replaces the conventional bulky and costly falling film equipment. The plate evaporator has a wide plate gap, a wide channel opening and laser welding that ensuring the vacuum low pressure evaporation process to be performed in both aqueous and organic systems.More +
