As a trusted manufacturer since 1998, Anping County Boli Hardware Wiremesh Products Factory is proud to introduce our High Efficiency Double-layer Spiral Coil Steam-Cooled Evaporator with 12mm Tube Diameter. This advanced evaporator is engineered to deliver superior heat transfer performance and energy efficiency, making it an ideal solution for various industrial cooling and evaporation processes. Our decades of experience in metal fabrication and global export—covering markets across North America, Europe, Asia, and beyond—ensure that every unit meets rigorous quality standards.
The unique double-layer spiral coil design maximizes the contact surface area between the steam and the process fluid, significantly enhancing the heat exchange rate. With a precisely engineered 12mm tube diameter, the evaporator optimizes fluid flow dynamics while minimizing pressure drop. Whether you need a standard unit or a customized configuration, our factory is equipped to deliver reliable, high-performance evaporators tailored to your specific operational requirements.
Below we provide a detailed overview of the product features, technical specifications, and benefits that make this evaporator a preferred choice for professionals in the chemical, food processing, pharmaceutical, and HVAC industries.
Key Features & Technical Specifications
- Double-layer Spiral Coil Design: Two concentric spiral coils provide extended heat transfer surface, improving thermal efficiency by up to 30% compared to single-layer designs.
- 12mm Tube Diameter: Optimized for a balance between high flow capacity and effective heat exchange, suitable for both low-viscosity and medium-viscosity fluids.
- Steam-Cooled Operation: Uses steam as the cooling medium, allowing precise temperature control and rapid heat dissipation in closed-loop systems.
- High Quality Materials: Constructed from durable stainless steel (304/316L) or carbon steel, with options for corrosion-resistant coatings. All materials are food-grade compliant when required.
- Customizable Configurations: Available in various sizes, connection types (flanged, threaded, or welded), and pressure ratings up to 10 bar (standard). Custom pressure and temperature ranges are available upon request.
- Compact Footprint: The spiral coil design allows for a compact structure, saving valuable floor space while maintaining high performance.
- Easy Maintenance: The coil assembly can be easily removed for cleaning or inspection, reducing downtime and maintenance costs.
