Spiral Plate Heat Exchanger

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 of fouling, excellent energy-saving effects, compact size, affordable price, 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 categorized into non-detachable (Type I) and removable (Type II, III) spiral plate heat exchangers based on their structural forms.

Basic Parameters

Spiral plate heat exchangers are specified with nominal pressures of PN 0.6, 1, 1.6, and 2.5 MPa (equivalent to original 6, 10, 16, and 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 steel 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 flow rate: 1m/Sec, gas flow rate: 10m/Sec).

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

Parallel and series combinations: same equipment and channel spacing.

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