Enamel Disc Heat Exchanger

Enamel disc Heat Exchanger operates based on three core principles: counter-current heat exchange, turbulent enhanced heat transfer, and high-efficiency heat conduction through disc interlayers. It consists of multiple stacked enamel discs forming independent cold and hot flow channels. High-temperature medium flows along disc gaps, cooling water flows reversely in disc interlayers, achieving efficient heat exchange through dense high-silicon enamel layer to complete cooling, condensation and waste heat recovery. With Q245R carbon steel as base material and high-temperature sintered enamel layer, it combines metal strength and glass-grade corrosion resistance. As a core heat exchange equipment for highly corrosive working conditions certified by China Standardization Administration, AIX Boiler, as an original factory, strictly follows Standardization Administration of China standards HG/T2056-2018, GB150, TSG21-2016, independently controlling design, manufacturing and testing to ensure safe, compliant, stable and durable products.

1. AIX Boiler Brand & Original Factory Core Advantages

AIX Boiler is a comprehensive chemical equipment manufacturer integrating R&D, design, production, installation, commissioning and EPC service, specializing in enamel disc heat exchangers, shell and tube heat exchangers, spiral plate heat exchangers, storage tanks, pressure vessels and other equipment. We have intelligent workshops, professional enamel sintering and NDT teams, complete forming and pressure testing equipment, realizing independent production from plate procurement and re-inspection, CNC cutting, stamping, enamel sintering, assembly, sealing test, hydrostatic test to finished product delivery without middlemen, providing higher cost performance and more controllable delivery time with the same quality. With years of deep cultivation in heat exchange equipment industry, our products have passed many authoritative tests, complying with Class I pressure vessel safety standards, adapting to strict working conditions in chemical, petroleum, pharmaceutical, dyestuff, metallurgy and other industries, serving thousands of enterprises nationwide, winning market trust with stable quality, professional technology and perfect service, becoming a trustworthy brand manufacturer in enamel disc heat exchanger field.

2. Working Principle & Structural Features

Enamel disc heat exchanger adopts stacked disc structure, composed of upper cover, lower cover, enamel discs, PTFE-coated gaskets and fasteners, with cold and hot media completely isolated without cross-contamination. New six-hole design ensures uniform fluid distribution, reduces single disc thickness to improve cooling water flow rate, heat transfer efficiency increased by more than 50% compared with standard type; 10mm thick gasket has small expansion and contraction, high pressure resistance, suitable for high vacuum sealing; smooth disc surface is not easy to scale, easy to maintain; modular disc design can flexibly adjust heat exchange area by adding or reducing discs, local replacement available for damage, greatly reducing use cost. AIX products resist acid, alkali and organic solvents, with wide temperature range, suitable for heat exchange and condensation of most non-toxic, non-explosive, highly corrosive media.
