Product Model: T20BW
Product Category: Semi-welded Plate Heat Exchanger
Core Positioning: Specifically designed for the cooling of corrosive media and the heating of various media
The T20BW features an innovative semi-welded structural design, with high-quality stainless steel corrugated plates as its core component. Two plates are attached back-to-back and welded into an independent plate cassette along the dedicated sealing groove via laser welding technology, which serves as the exclusive flow channel for corrosive media. Gaskets are used for sealing between each plate cassette, forming the flow channel for conventional media.
During operation, media such as refrigerant circulate between plate cassettes and only come into contact with two of the four annular gaskets at the inlet and outlet. This design greatly reduces the contact area between the medium and the sealing parts, which not only ensures the sealing performance of the flow channels but also effectively prevents the erosion of sealing parts by corrosive media, achieving efficient isolation and heat exchange between cold and hot media.
- Wide temperature range & high pressure resistance: The operating temperature ranges from -38℃ to 200℃, adapting to various working conditions of high and low temperatures; the maximum design pressure can reach 30 bar, meeting the heat exchange requirements of medium and high pressure.
- Robust and stable structure: Adopting a rigid mechanical structure design, it has strong overall compression and deformation resistance, ensuring high operational stability and a long service life of the equipment.
- Excellent sealing and leakproof performance: The dual sealing design of laser welding and gaskets delivers outstanding leakproof performance, effectively avoiding medium leakage and cross-contamination, and greatly improving the safety of use.
- Superior corrosion resistance: The plate cassette-type welded flow channel is specially designed for corrosive media, capable of efficiently handling various aggressive media and adapting to complex chemical heat exchange scenarios.
- High flexible adaptability: The overall size of the equipment can be customized on demand, and the heat exchange area can be flexibly adjusted to match the actual heat exchange needs of different sites and processes.
- Compact installation footprint: The compact structural design features small volume and light weight, requiring minimal installation space and being suitable for installation scenarios with limited factory space.
- Equipped with laser welding technology, the weld seams are tight and uniform, the plate cassette flow channels have excellent sealing performance, and there is no risk of medium leakage.
- The plates are made of high-quality stainless steel, balancing high heat transfer efficiency and strong corrosion resistance, and adapting to various harsh medium working conditions.
- The low-contact design between medium and sealing parts reduces the wear of sealing parts and lowers the later maintenance cost of the equipment.
- The semi-welded structure integrates the advantages of corrosion and pressure resistance of welded type and flexible maintenance of gasket type, balancing working condition adaptability and operational convenience.
Relying on its core characteristics of corrosion resistance, temperature resistance and pressure resistance, the T20BW semi-welded plate heat exchanger is widely used in industries such as chemical industry, pharmaceutical industry, refrigeration and metallurgy. It is especially suitable for heat exchange working conditions where one side is corrosive medium and the other side is conventional medium, and can complete core processes such as cooling of corrosive media, heating of process media and refrigerant heat exchange. It is commonly applied in ammonia refrigeration/freon refrigeration systems, acid-base medium cooling, chemical raw material heating and other scenarios.
