Four-Sided Demountable Plate-and-Frame Heat Exchanger - Product Introduction

I. Core Product Definition

II. Core Structure and Core Advantages

(I) Core Structure Composition

• Heat Transfer Plates: As the core heat transfer components, they are made of corrosion-resistant and high thermal conductivity materials such as stainless steel and titanium alloy. The surface is designed with enhanced heat transfer structures like corrugations and concave-convex patterns to increase heat transfer area and improve heat transfer efficiency.

• Four-Sided Demountable Frame: Made of high-strength carbon steel or stainless steel, the frame can be independently demounted on four sides without overall disassembly of the equipment, reducing the difficulty of maintenance operations.

• Sealing System: Equipped with special gaskets that are high-temperature resistant, high-pressure resistant, and corrosion-resistant, which fit the sealing surfaces of the plates and frame to ensure no medium leakage and adapt to different working conditions.

• Fasteners: Adopt high-strength bolts, nuts, and other connectors to ensure the overall sealing performance and structural stability of the equipment after assembly, with convenient disassembly and assembly.

(II) Core Product Advantages

• Four-Sided Demountability for Easy Maintenance: Different from traditional plate-and-frame heat exchangers with single-sided or double-sided demountable structures, it can be independently demounted on four sides, allowing quick access to core internal components such as plates and seals. It shortens the time for maintenance, cleaning, and replacement of accessories, and significantly reduces downtime and maintenance costs.

• High-Efficiency Heat Exchange, Energy Conservation and Consumption Reduction: The enhanced heat transfer plate design increases the heat transfer coefficient and heat transfer area. The countercurrent/cross-flow contact between cold and hot media enables full heat transfer, with heat transfer efficiency 15%-30% higher than that of traditional equipment, effectively reducing energy consumption.

• Wide Adaptability and Flexible Working Conditions: According to different media (water, oil, chemical fluids, etc.), temperature (-40℃-300℃), and pressure (≤4.0MPa) working conditions, it can customize plate materials, specifications, and sealing solutions, suitable for multiple industries such as chemical, metallurgy, electric power, food, and pharmaceutical.

• Stable Structure and Long Service Life: The combination of high-strength frame and high-quality heat transfer materials ensures excellent impact resistance, corrosion resistance, and pressure resistance. The sealing system has strong sealing performance and low wear rate, with a service life of 8-10 years under normal equipment maintenance.

• Flexible Assembly and Convenient Capacity Expansion: The heat transfer area can be flexibly adjusted by increasing/decreasing the number of heat transfer plates to meet the changing needs of production load. Capacity expansion and renovation do not require replacing the entire equipment, resulting in low investment costs.

III. Application Scenarios
