Features

Spiral Plate Group Two steel plates are rolled to form two sets of spiral channels. The channel spacing is supported by spacer columns to ensure uniform fluid distribution and structural stability.
Sealing Design The ends of the channels are sealed by welding or gaskets to prevent fluid leakage. Different materials (such as stainless steel, titanium alloy, etc.) can be selected based on the medium characteristics.
Inlet and Outlet Configuration Cold and hot fluids enter from the tangential inlet on both sides of the spiral body and flow along the spiral path, prolonging the heat exchange time and improving efficiency.
Double Channel Design The two fluid channels are separated by spacer columns welded during the rolling process or a special structure during rolling to avoid cross-contamination.
Shell A cylindrical shell wraps the spiral plates, with both ends sealed. It is usually designed as detachable for cleaning.
Inlet and Outlet Connectors Located at both ends of the spiral channels, the fluid flows in/out from the center or is distributed along the periphery, depending on the flow direction (full counter-flow or cross-flow).

Product Intro

Spiral Plate Heat Exchanger

Structure and Design

The spiral plate heat exchanger is formed by rolling two parallel metal plates into concentric spiral-shaped channels. The cold and hot fluids flow counter-currently or cross-currently within the spiral channels. The interior usually has a welded sealing structure and cannot be disassembled for cleaning or maintenance.

The detachable plate heat exchanger is composed of multiple corrugated plates stacked together. The plates are sealed with rubber gaskets, forming alternating cold and hot fluid channels. The plates can be disassembled by loosening the compression bolts, making it convenient for cleaning, replacement or expansion.

Spiral Plate Heat Exchanger

Application Scenarios

The spiral plate heat exchanger is suitable for high-viscosity/dirty media: such as sludge, fluids containing fibers or particles. The welded structure has a strong pressure-bearing capacity (up to 2.5 MPa or more).

The flow channels have a large curvature and are not prone to clogging.

The detachable plate heat exchanger is suitable for clean media: such as water, steam, oil and other low-viscosity fluids. For media prone to scaling, frequent cleaning is required. Due to the limitation of the gaskets, it is usually used in occasions with a pressure of ≤1.6 MPa and a temperature of ≤200℃.

Maintenance and Cost

The maintenance of spiral plate heat exchangers is challenging: when clogged or leaking, overall repair or replacement is required.

The detachable plate heat exchanger is convenient for maintenance: individual replacement of plates or gaskets is possible, and cleaning is easy.

Spiral Plate Heat Exchanger

Typical Applications

Spiral plate heat exchangers are used in industries such as chemical engineering, papermaking, wastewater treatment, and heating/cooling of high-viscosity fluids.It is widely applied in fields such as chemical engineering, petroleum, pharmaceuticals, food, energy and environmental protection.

Removable plate heat exchangers are applied in HVAC, food and beverage, pharmaceuticals, and low-pressure steam condensation.
