Horizontal Spiral Plate Heat Exchanger

Product Overview

Spiral plate heat exchangers are heat exchange devices suitable for gas-gas, gas-liquid, and liquid-liquid applications, as well as for condensation and liquid evaporation heat transfer. This product boasts high heat transfer efficiency, strong self-cleaning ability, excellent energy-saving effects, compact size, affordable pricing, and reliable operation. It can be used in industries such as chemicals, petroleum, solvents, food, light industry, textiles, metallurgy, rolling steel, and coking. They are classified into non-disassemblable (Type I) and disassemblable (Type II, III) spiral plate heat exchangers based on their structural design.

Basic Parameters

The nominal pressure PN for spiral plate heat exchangers is specified as 0.6, 1, 1.6, 2.5 MPa (i.e., originally 6, 10, 16, 25 kg/cm²).²The test pressure is 1.25 times the working pressure.

The material for the contact part of the spiral plate heat exchanger with the medium is carbon steel Q235A, Q235AF, and stainless acid steel SUS321, SUS304. Other materials can be selected according to customer requirements.

Operating Temperature Range: Carbon steel: t=0～+350°C, stainless steel and acid-resistant steel: t=-40～500°C. The temperature and pressure reduction range shall comply with the relevant regulations for pressure vessels. When selecting this equipment, appropriate process calculations should be made to ensure the fluid in the equipment channel reaches turbulent flow. (Typical liquid velocity: 1m/s; gas velocity: 10m/s).

A single unit may not meet the usage requirements; multiple units can be combined, but the combination must comply with the following regulations:

Parallel and series combinations: Same spacing between equipment and channels.

Mixed Combination: One channel in parallel, one channel in series.
