Standalone Spiral Plate Heat Exchanger

Standalone 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 against scaling, compact size, affordable pricing, and reliable operation. It is used in industries such as chemicals, petroleum, solvents, food, light industry, textiles, metallurgy, rolling steel, and coking. Structurally, they are categorized into non-detachable (Type I) spiral plate heat exchangers and removable (Type II, Type III) spiral plate heat exchangers.

The nominal pressure PN of the spiral plate heat exchanger is specified as 0.6, 1, 1.6, and 2.5 MPa (equivalent to the original 6, 10, 16, and 25 kg/cm2), which refers to the working pressure the single channel can withstand. The test pressure is 1.25 times the working pressure.

Basic Parameters

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

 Allowable Working Temperature: 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. (Typically, liquid velocity: 1m/sec, gas velocity: 10m/sec.)

A single unit of equipment does not meet the usage requirements. Multiple units can be combined for use; however, 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.
