Product Description

Product Description

Spiral Plate Heat Exchanger

A spiral plate heat exchanger is a highly efficient and compact heat-transfer device constructed by rolling two parallel metal plates into a spiral channel. With the advantages of counter-current flow, self-cleaning turbulence, excellent fouling resistance, and natural absorption of thermal stress, it delivers up to 3× the heat-transfer efficiency of traditional shell-and-tube exchangers while occupying only 1/10 of the volume.
 
It is widely applied in energy, chemical processing, petrochemical, environmental protection, paper making, metallurgy, and waste-heat recovery systems, especially suitable for viscous media, particle-containing fluids, and corrosive process streams.

Material Options

Material Type	Grades	Plate Thickness
Carbon Steel	Q235, P355GH	4 mm
Stainless Steel	SUS304, SUS316L, SUS321, EN 1.4401, EN 1.4404	2 – 4 mm (large: 5 mm)
Special Alloys	Titanium, Hastelloy	2 – 4 mm
Optional	SiC Composite Coating	—

Product Features

1. High Heat-Transfer Efficiency
The spiral channel design generates strong turbulence, improving heat-transfer performance 1.5–3 times higher than traditional shell-and-tube exchangers.

2. Compact Structure
Achieves the same heat-transfer area with 1/3–1/2 the volume of a shell-and-tube unit, saving installation space.

3. Low Pressure Drop
Streamlined flow channels reduce flow resistance and energy consumption.

4. Excellent Anti-Fouling Ability
Continuous spiral flow produces shear forces that inhibit fouling and sludge deposition, extending cleaning cycles.

5. Broad Application Adaptability
Handles corrosive fluids, high-viscosity media, particulate-containing fluids, and wide temperature/pressure conditions.

6. High Sealing ReliabilityDual-seal structure and fewer flange interfaces minimize the risk of leakage.

7. Long Material Residence Time
The spiral path increases contact time, suitable for full heat-exchange reactions or long-residence applications.

8. Cost-Effective Manufacturing
Simple internal structure with reduced material usage offers an economical alternative to traditional heat-exchange equipment.
