Type III Through-Flow Spiral Plate Heat Exchanger
| Product Details
Product Overview
The through-flow spiral plate heat exchanger is an almost ideal heat exchange device. In this exchanger, the two fluids flow in a true counter-current configuration, enabling both streams to achieve identical flow characteristics. It is well suited for convective heat transfer between gas–gas, gas–liquid, and liquid–liquid systems, as well as for steam condensation and liquid evaporation processes.
The two end faces of the spiral channel are edge‑bent and alternately welded to form a closed seal, with a top cover and gasket serving as the sealing assembly. The dual channels can be easily cleaned mechanically, making this design particularly well suited for media that are heavily contaminated or prone to fouling. It is currently employed in industries such as environmental wastewater treatment, sewage treatment, renewable energy, food processing, pharmaceuticals, coking, agrochemicals, and fine chemicals.

Product Features
1. High operational reliability: The two channels are uniformly welded and sealed, ensuring that the two heat-exchange media do not mix.
2. Effective recovery of low-temperature thermal energy: The two heat-transfer fluids can undergo counter-current heat exchange. It is well suited for heat transfer across small temperature differences and for recovering low-temperature thermal energy.
3. Not easily clogged: The fluid flows through a single channel, allowing for higher flow velocities than other types of heat exchangers. Fouling is less likely to accumulate, and the channel’s design provides self‑cleaning action, making it easy to flush away deposits.
.
4. High heat transfer efficiency: The overall heat transfer efficiency coefficient reaches a maximum of 3,300 W/(m²·K), with a heat transfer efficiency that is 30% to 50% higher than that of shell-and-tube heat exchangers.
5. Pressure reduction: Cross-flow heat exchange occurs between gas and liquid, and the condensation–cooling section features a favorable gap, resulting in low pressure drop.
6. Stable operation: It features two long, uniform channels, enabling the medium to be heated and cooled uniformly and allowing precise control of the outlet temperature.
