Principle A plate and frame heat exchanger as known as gasketed plate heat exchanger is a high efficiency heat exchanger that assembled from metal sheets with corrugated pattern and different kind of gaskets. Plate heat exchangers are the ideal equipment for heat exchange between liquid-liquid and liquid-vapor.In the case of the same pressure loss, the heat transfer coefficient is 3-5 times higher than that of the tube heat exchanger, but the floor space is one-third of the tube heat exchanger, and the heat recovery rate can be as high as 90% or more. Maximum volume: 5000m3 /h;Maximum design pressure: 25bar Maximum temperature: 200 celsius degree; Minimum difference in temperature: 0.5-1 celsius degree Nozzle diameter: DN15~DN500;Plate thickness: 0.4mm - 1.2mm Gasket material:NBR, EPDM, HNBR, HT-NBR, HEPDM, CR,VITON/FKM Fixed and movable plate material: Carbon Steel, Stainless Steel, and others on request. Plate material:AISI304, AISI316, AISI316L, Titanium,Ti-Pa,Hastelloy C276,254SMO,Nickel, AISI904L. Plate heat exchanger High heat transfer coefficient The design of the plate corrugation is aimed at the high thermal conductivity. The special flow path are formed by the plate corrugation causing strong disturbance flow at a very low flow rate, which is called turbulent flow. And the disturbance flow can be self-cleaning to prevent fouling and thus the heat transfer efficiency is high. Plate heat exchanger Large logarithmic temperature difference The temperature difference at the end is small, and the plate heat exchanger is mostly a cocurrent or countercurrent type of flow. In addition,there's no bypass flow. Plate heat exchanger Small footprint and easy maintenance The plate heat exchanger has a compact structure, and the heat exchange area per unit volume is 2-5 times that of the shell-and-tube type, and the floor area of the plate heat exchanger is about 1/2-1/3 of the shell - tube heat exchanger when achieving same heat exchange capacity .
Product principle The plate and shell heat exchanger adopts a circular corrugated heat exchanger plate that welded into a heat exchanger lathed bundle and combined with the structure of the pressure vessel shell. It also has a high heat transfer efficiency,compact structure and resistant to high temperature & pressure like shell tube heat exchanger. The plate and shell heat is durable under high temperature & pressure,large temperature difference and thermal shock, which is in a leading position in the industry.

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.

Product introduction 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. Plate condensers are specially developed for condensing steam under low pressure or vacuum conditions in evaporation and distillation systems. It can meet a variety of specific applications and capabilities requirements. The steam inlet fitting is large and the two condensate outlets are small. The cooling water fitting is a medium size and is located in the center of the plate. Maximum heat transfer area: 500m2/set; Maximum design pressure:16bar Maximum temperature:200 celsius degree; Nozzle diameter:DN50~DN700 Plate thickness:0.5mm-1.2mm; Gasket material:NBR, EPDM, HNBR, HT-NBR, HEPDM, CR, VITON/FKM Fixed and movable plate material: Carbon Steel, Stainless Steel, and others on request. Plate material:AISI304, AISI316, AISI316L, Titanium, Ti-Pa,Hastelloy C276,254SMO,Nickel, AISI904L. Features Plate condenser Lower cost Due to the high heat transfer efficiency, this means less heat exchange area and higher cost efficiency than conventional shell and tube type, especially when stainless steel or titanium is required. The compact design also saves space, thus reducing transportation and installation costs. Plate condenser Less fouling Due to the high strength turbulence created by the specially designed corrugated sheets, there is less fouling on the cooling water side than the shell and tube condenser. Plate condenser Easy to clean The cooling water side is easy to clean, whether in the way of mechanical or chemical. Plate condenser Easy to expand Just add an extra "plate group" in the existing frame. Plate condenser Complete counterflow A greater degree of subcooling of non-condensable gases can be achieved compared to shell and tube equipment. Therefore, the load of the vacuum pump will be reduced. Range of application Alumina, food industry, sugar industry, beverage industry, industrial wastewater, etc.
Product principle The working principle of the plate evaporator is to compress the secondary steam generated by the equipment through the configured compressor, then raise the pressure and temperature to a certain range, and finally transfer it to the relevant heating chamber of evaporator as heating steam. Finally, to perform the condensation heat release program, so that it can help the latent heat of the steam and the recycling can be effectively obtained. Maximum heat transfer area: 500m2/set; Maximum design pressure:16bar Maximum temperature:200 celsius degree; Nozzle diameter:DN50~DN500 Plate thickness:0.4mm;Gasket material:NBR, EPDM, HNBR, HT-NBR, HEPDM, CR, VITON/FKM Fixed and movable plate material: Carbon Steel, Stainless Steel, and others on request. Plate material:AISI304, AISI316, AISI316L, Titanium, Ti-Pa,Hastelloy C276,254SMO,Nickel, AISI904L. Advantages Plate evaporator High heat transfer efficiency The plate evaporator is ingenious in design, so the heat transfer efficiency is higher than that of the general evaporator. Generally, the plate evaporator area only needs about one-half of the tube evaporator then can achieve the same evaporation effect. Plate evaporator Compact overall structure The whole structure is compact, floor space is small, and there is no need to invest too much manpower and material resources in the later use process. For some maintenance work, it only needs to be carried out in the original space range, and it's very simple whether it is disassembled or installed . Plate evaporator Diversification of components The heat exchange area can be effectively adjusted according to the customer's needs: now the heat exchange area of different evaporators has different ranges, since the heat exchanger plates can be disassembled, so multiple components with multiple skills and more new functions can be provided through adjusting number of plates and changing relative flow path. Plate evaporator Small heat loss Because this type of equipment is compact in structure and relatively light in weight, compared with tubular evaporators, it also reduces heat loss, and such equipment usually does not need to be insulated. Plate evaporator Less pressure loss Under the same heat transfer coefficient condition, such evaporator equipment can control the pressure loss within a certain range by rotating a reasonable flow rate.Compared with tubular evaporator,it can reduce 2/3 pressure loss. Plate evaporator Stable and safe operation Different sealing procedures are designed on the sealing device between the plates, and Range of application Metallurgy, food industry, paper industry, air conditioning, chemical and desalination industries
