Plate & Frame Heat Exchanger

Shanghai Empire Mechanical Engineering Co.,Ltd is one of the leading China plate heat exchangers manufacturers, welcome to wholesale plate cooler, plate evaporater, heat transfer equipment, gasketed plate heat exchangers, gasketed plate and frame heat exchanger from our factory.

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 .

1. Efficient heat transfer Gasketed plate-and-frame heat exchangers (GPHEs) provide efficient heat transfer in compact equipment with a small footprint - much smaller and more efficient than shell-and-tube heat exchangers. Plate heat exchangers are designed to optimize heat transfer, because the corrugated plates provide by far the greatest surface area through which the heat can be drawn from one gas or liquid to the other.The units also have a flexible design and are easy to service and maintain. 2. Types of gasketed plate heat exchangers Industrial -extremely versatile range of heat exchangers for use in all types of industries Industrial semi-welded -used in refrigeration when gaskets are not suitable for one of the media and when higher design pressures are needed WideGap -used for applications involving fibrous liquids, highly viscous fluids, and fluids containing coarse particles evaporators-tailor-made, rising film plate surface evaporator condensers -a compact, plate surface vacuum condenser Material available for 0.5 & 0.6mm 304SS, 316SS, Titanium, ASMO254, Hastelloy C-276, Nickel Ni201, 904L More details please contact us directly . 3.

They are widely used in duties for heating, cooling, heat recovery, evaporation and condensation in industries ranging from HVAC, refrigeration, engine cooling, dairy and food to heavier processes like chemical processing, oil production and power generation.

What is a plate heat exchanger? Plate heat exchanger is a new type of high efficiency heat exchanger composed of a series of corrugated metal sheets. Thin rectangular channels are formed between various plates through which heat is exchanged. Plate heat exchanger is an ideal equipment for liquid - liquid and liquid - steam heat exchange. Plate material: 304, 316,316L, titanium etc Thickness of plate:0.4mm-0.8mm Sealing ring material : nitrile rubber (NBR), EPDM, fluorine rubber. Overall heat transfer coefficient:3500-7500W/m�²�·K Advantages: 1.Heat transfer conditions:It is especially suitable for liquid-liquid heat exchange with large flow and small temperature difference. 2.Thorough cleaning:All can be disassembled for thorough cleaning. 3.Easy to change the heat exchange area or process combination: By increasing or reducing a few plates, the heat transfer area can be increased or reduced. By changing the plate arrangement or replacing several plates, the required flow combination can be achieved to adapt to the new heat transfer conditions. 4.Small in size :Compact and lightweight structure, small footprint, the floor space is one-third of the tube heat exchanger. 5.Light weight:The plate thickness of the plate heat exchanger is only 0.4~0.8mm, while the thickness of the heat exchange tube of the shell-and-tube heat exchanger is 2.0~2.5mm. The shell-and-tube shell is much heavier than the frame of the plate heat exchanger .The plate heat exchanger is generally only about 1/5 of the weight of the shell-and-tube type. 6.Low price: Using the same material, under the same heat exchange area, the price of the plate heat exchanger is about 40%-60% lower than that of the shell-and-tube type.�  7.High heat exchange efficiency :The heat transfer coefficient is 3-5 times higher than that of the tube heat exchanger 8.Low heat loss: The heat recovery rate can be as high as 90% or more. 9.The logarithmic mean temperature difference is large, and end temperature difference is small.
