Non-separable helical plate heat exchanger

Horizontal Split-Sheet Spiral 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, compact size, affordability, and reliable performance. It is used in industries such as chemicals, petrochemicals, solvents, food, light industry, textiles, metallurgy, rolling, and coking. They can be classified into non-disassemblable (Type I) and disassemblable (Type II, III) spiral plate heat exchangers based on their structural forms.

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 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.

Allowable Working Temperature: Carbon steel, t=0～+350℃; stainless steel and acid-resistant steel, t=-40～500℃; 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 passage reaches a turbulent state. (Generally, liquid flow rate is 1m/Sec, gas flow rate is 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 Configuration: One channel in parallel, one channel in series.
