Product Definition
The Vertical Spiral Plate Heat Exchanger is a high-efficiency thermal transfer unit constructed by spirally winding two metal plates into dual concentric channels. Engineered for vertical installation (compatible with horizontal setup), it utilizes counterflow heat exchange to maximize waste heat recovery while featuring a removable end cap for accessible maintenance.
Structural Features
Single-Side Removable End Cap
Enables direct access to flow channels for mechanical cleaning without full disassembly, ideal for fouling-prone media.
Vertical Compactness
≤50% footprint vs. shell-and-tube units, optimized for space-limited plants.
Spiral-Induced Turbulence
Long spiral paths generate intense fluid mixing, enhancing heat transfer and resisting blockage.
Installation Flexibility
Designed for vertical or horizontal mounting to adapt to piping layouts.
Technical Advantages
Counterflow Efficiency
Recovers >92% waste heat in applications like acid cooling or sludge heating, cutting energy costs by 25–40%.
Anti-Clogging Robustness
Self-scouring spiral channels minimize particulate buildup; suitable for slurries, wastewater, and high-viscosity fluids.
Low-Maintenance Operation
Removable end cap allows rapid cleaning without gasket replacement, reducing downtime by 70%.
Thermal Stress Resilience
Spiral-wound structure absorbs differential expansion, ensuring integrity under thermal shock (−196°C to 550°C).
Application
Proven in demanding industrial processes:
- Chemical Processing : Sulfuric acid chilling, polymer slurry heating.
- Waste-to-Energy : Flue gas scrubbing, biogas upgrading.
- Mining & Metallurgy : Slurry cooling, leaching solution heat recovery.
- Pulp & Paper : Black liquor concentration, effluent preheating.
