BR 0.24
The plate-type heat exchangers are divided into BR type and BRB type with the various models shown as follows:
The first letter B represents the plate type heat exchanger.
The second letter R represents the V- shaped corrugation, for example,B stands for V-shaped variable- section corrugation.
The third letter represents that the single plate nominal heat exchanging area is 0.2㎡.
The fourth digital stands for a design pressure of 1.0MPa.
The fifth digital represents the overall heat exchanging area is 15㎡.
The sixth letter N shows that the sealing material is made of Buna-N rubber, just like E standing for EPDM.
The seventh symbol refers to the floor-type movable pressure plate; for example,I refers to the double support frame composed of fixing plate columns. (Hanging type).

Plate heat exchangers are used in food and beverageprocessing.
1. all kinds of dairy products: fresh milk, milk powder, milkdrinks, yogurt and sO on;
2. vegetable protein drinks: peanut milk, milk tea, soymilk, soy milk drinks, etc.
3. juice drinks: fresh fruit juice, fruit tea and so on.
4. cool tea drinks: tea drinks, reed drinks, fruit andvegetable drinks, etc.
5. seasoning: soy sauce, rice vinegar, tomato juice, sweetchili sauce, etc.
6. breweries: beer, rice wine, rice wine, wine and so on.
The plate heat exchanger is applied to other industrialliquid treatment.Pharmaceutical, printing and dyeing, heating and heaexchange, chemical, power plant, swimming bathheating, petroleum, metallurgy, hot water, ship,machinery, paper, textile, geothermal utilization,environmental protection, refrigeration.
Characteristics of plate heat exchanger
The plate type heat exchanger has the characteristics of highheat exchange efficiency, high heat recovery rate, small heatloss, small area of heat loss, small space area, flexibleassembly and assembly, easy operation, easy installation anddisassembly, long service life, less investment and safe use.The heat transfer coefficient of plate type heat exchanger is 3-5 times higher than that of tube type heat exchanger under thesame pressure loss. The product has only 1/3 of the tube type,and the heat recovery rate can reach as high as 90%.
Heat transfer plate material:
1. stainless steel: SUS304/SUS304L/SUS31 6/SUS316L (suitablefor corrosive conditions of acid and alkali medium, notsuitable for chloride ion).
2. industrial pure titanium: TAE (caustic soda, salt making, low temperature seawater freezing and chloride ion corrosion).
3. ultra low carbon stainless steel: 00Cr1 8Ni14Mo2Cu2 (organicsolvent and intercrystalline and chloride ion corrosionoccasions).
Process flow of plate heat exchanger
1. Because of the special effect of the plate corrugated surface, the .fluid flows along the corrugated channel. The velocity direction ofthe plate heat exchanger changes constantly, which results in thestrong end-movement of the fluid at a small flow rate, thusstrengthening the heat transfer process. It effectively improves theheat transfer capability and has the outstanding advantages ofcompact structure, low metal consumption, flexible operation andlong service life.
2. the process of heat exchanger is composed of many plates assembled according to a certain process and requirements of thebuyer. When assembling, A and B plates are arranged alternately,and a network is formed between the plates. The sealing gasketseals the cold and hot media in the heat exchanger, and at the same time, the cold and hot media are separated reasonablywithout mixing. Exchange SO as to achieve the desired effect.
3. There are many kinds of flow combinations of plate heatexchangers, which are realized by different reversing plates anddifferent assemblies. The process combination can be divided into single process, multi process and mixed process.
