Plate heat exchanger
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.

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.
-
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.
-
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 .
-
Easy to change heat transfer area or process combination
As long as several plates are added or reduced, the purpose of increasing or decreasing the heat exchange area can be achieved. Changing the plate arrangement or replacing several plates can achieve the required path combination to adapt to the new heat exchange conditions.
-
Low investment
With the same heat exchange capacity, when compared with the shell and tube heat exchanger,because of the decrease of heat exchange area, floor space, fluid resistance, cooling water consumption etc, plate heat exchanger has much lower expense on equipment investment, base investment, power consumption etc.
-
Safe and reliable use
double seal are designed on the sealing device of the plate, and there is a signal slot. Once the leakage occurs, it can be discharged outside the heat exchanger, which prevents the two media from mixing,and at the same time it can be a security alarm.
