Industrial Ss Semi Welded Plate Heat Exchanger , Titanium Gasketed Flat Plate Heat Exchanger

Compact Size

· As a result of the high efficiency, less Heat Transfer area is required, resulting in a much smaller Heat Exchanger than would be needed for the same duty using other types of Heat Exchangers. Typically a plate Heat Exchanger requires between 20-40% of the space required by a tube and shell Heat Exchanger.

Close Approach Temperature

· The same features that give the plate Heat Exchanger its high efficiency also makes it possible to reach close approach temperatures which is particularly important in heat recovery and regeneration applications. Approach temperatures of 0.5°C is possible.

Multiple Duties in a Single Unit

· The plate Heat Exchanger can be built in sections, separated with simple divider plates or more complicated divider frames with additional connections. This makes it possible to heat, regenerate, and cool a fluid in one Heat Exchanger or heat or cool multiple fluids with the same cooling or heating source.

Structure Of Semi Welded Plate Heat Exchanger:

This product is designed specifically for the refrigeration industry, semi-welded plate heat exchanger (ammonia evaporator), ammonia walking welding channel, coolants (calcium chloride solution, glycol, etc.) take the gasket channel, this structure not only ensures side channel of reliable sealing ammonia, and both advantages detachable. Another also apply to the vapor - liquid phase change heat and there is liquid - liquid without phase change and security requirements of high heat applications.

The laser semi welding heat exchanger is used in the situation where the gasket cannot be used in the original special situation or the safety requirements are relatively high.
The laser welding is used on one side of the special material, which requires high cleanliness. The other side is in the form of gasket. The performance of half welded heat exchanger is completely consistent with that of plate heat exchanger except that the position of gasket on one side is laser welded.

Plate heat exchanger design selection:

(1) Physical parameters of cold and hot media, such as pH, chloride content, viscosity, density, thermal conductivity, specific heat, etc.
(2) The inlet and outlet temperatures of cold and hot media.
(3) Flow of cold or hot medium or flow of one of them.
(4) Cold and hot medium pressure loss requirements.
(5) Intrinsic characteristics of plate heat exchangers, such as plate material, seal gasket material, etc

Advantages

- Including all the advantages of detachable plate

- Special material channel adopts laser welding

- Sealing ring CR or PTFE gasket material

- High stability and safety of one side welding

- More efficient and detachable than full weld
