PEQ fully welded plate heat exchanger

Principle of the fully welded plate heat exchanger:

A fully welded plate heat exchanger consists of many corrugated heat transfer plates spaced at certain intervals, sealed by welding. During panel assembly, two groups are arranged alternately, and sealing is achieved by welding between plates. The interior of the plate is a herringbone corrugated plate, which allows the fluid to flow at low velocities to create turbulence, thereby enhancing heat transfer. The two heat exchange media flow separately into their respective channels, forming counterflow or parallel flow that exchanges heat through each plate.

Features of the fully welded plate heat exchanger: 1. Compact structure, small footprint, high heat exchange efficiency, high pressure capacity (up to 3.0Mpa), high temperature resistance (maximum temperature up to 250~300°C), reliable operation. 2. High heat transfer efficiency: Heat exchange between the medium in the heat exchanger is achieved through plate bundles. The plates forming the plate bundle are pressed into shape by specialized molds, structurally similar to ordinary detachable plate heat exchangers, offering advantages such as high heat transfer efficiency, large flow rate, low fluid pressure drop, and minimal heat dissipation loss. 3. Flexible and convenient: A single mold can press plates of different lengths into different specifications and bundles, forming product series of the same width. With many specifications and models, there is a wide range of choices, better meeting working conditions. 4. Wide range of applications: The plate bundles and clamping plates all use welded structures, enabling safe and stable operation under conditions such as gas condensation, liquid cooling, heating, and evaporation in environments where ≤300°C, pressure ≤ 3.0MPa, or working media corrode sealing gaskets, as well as in production processes with flammable, explosive, toxic media and high environmental safety requirements. Therefore, it combines the advantages of detachable plate heat exchangers with the characteristics of being suitable for high temperature and high pressure.
