Looking for a Fully welded plate and frame heat exchanger? Then JINFAN is just right.
We are a first-class full welded plate heat exchanger manufacturer & supplier. The fully welded plate and frame heat exchanger is a new concept in heat transfer technology. It combines the advantages of both gasket and frame plate heat exchangers and shell and tube heat exchangers.
The fully welded plate heat exchanger achieves efficient heat exchange between two fluids through the welding structure between metal plates. It combines the high heat transfer efficiency of the plate heat exchanger with the high-strength sealing performance of the shell and tube heat exchanger, and is particularly suitable for heat exchange conditions of high temperature, high pressure or corrosive fluids.
The plates are made of fishbone corrugation, diamond corrugation or special customized patterns to increase the turbulence and heat transfer coefficient of the fluid. Adjacent plates are welded in pairs to form a closed channel, and the hot fluid and the cold fluid enter the heat exchanger from the inlet and outlet on both sides, respectively, and enter their independent plate channels. Laser welding or TIG (argon arc) welding is commonly used to achieve high sealing. The welds are located at the edges and contact points of the plates, and no rubber gaskets are required. All plates are welded or clamped in a rigid shell to ensure structural strength and adapt to the interface pipes. The equipment is equipped with inlet and outlet ports for easy connection to the user system.
✅ Compact and space-saving design. WPHE occupies less floor space compared to traditional shell and tube heat exchangers.
✅ Provide efficient heat transfer due to its large surface area and turbulent flow created by the pattern of welded plates. This results in improved thermal performance and reduced energy consumption.
✅ Constructed using corrosion-resistant materials such as stainless steel or titanium. This makes it ideal for handling corrosive fluids and environments, ensuring long-term durability and reliability.
✅ Understand high temperatures and pressures, making it suitable for applications that require heat transfer in extreme operating conditions.
✅ Designed for easy maintenance and cleaning. The plates can be easily accessed and cleaned, reducing downtime and ensuring optimal performance.
✅ Advanced laser welding technology is suitable for high temperature, high pressure or corrosive media, avoiding gasket aging problems.
✅ The welded sealing structure greatly reduces the risk of leakage and is suitable for the heat transfer of corrosive fluids.
✅ The corrugated plate design optimizes the heat exchange area and turbulence effect, and the heat exchange efficiency is much higher than the shell and tube type.
✅ No need to frequently replace gaskets, eliminating the trouble of disassembly and assembly, and long-term operation is more reliable.
✅ Provide 316L, titanium, hastelloy, etc. to meet a variety of corrosion conditions.
