Product Overview

Spiral plate heat exchangers are a type of heat exchange equipment 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 against fouling, excellent energy-saving performance, compact size, affordable pricing, and reliable operation. It can be used in industries such as chemicals, petrochemicals, solvents, food, light industry, textiles, metallurgy, rolling steel, and coking. They are categorized by structural design into non-disassemblable (Type I) and disassemblable (Type II, III) spiral plate heat exchangers.


Basic Parameters

The nominal pressure PN for spiral plate heat exchangers is specified as 0.6, 1, 1.6, and 2.5 MPa (equivalent to the original 6, 10, 16, and 25 kg/cm²), with the test pressure being 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 within the equipment channel reaches turbulent flow. (Typically, liquid velocity is 1m/Sec, gas velocity is 10m/Sec).

A single unit may not meet the usage requirements; multiple units can be combined, but they must adhere to the following regulations:

Parallel and series combinations: same equipment and channel spacing.

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