Anping County Boli Hardware Wiremesh Products Factory, established in 1998, brings over two decades of expertise in manufacturing high-quality stainless steel spiral evaporator coils. Our coils are designed for efficient heat transfer in evaporation and condensation processes, with a 1-year warranty and a comprehensive Mill Test Report included to guarantee material traceability and performance. Whether you need a standard coil or a custom dimension, we deliver reliable solutions that meet the rigorous demands of industrial applications.
Our spiral evaporator coils are crafted from premium stainless steel (304 or 316L), featuring a continuous spiral design that maximizes surface area for optimal thermal efficiency. The smooth inner and outer surfaces minimize fouling and pressure drop, ensuring long service life even in corrosive environments. Each coil undergoes strict quality control, and the accompanying Mill Test Report provides certified chemical composition and mechanical properties.
Key Features & Specifications
- Material Grades: Available in SS304, SS304L, SS316, SS316L – suitable for food, pharmaceutical, and chemical industries.
- Customizable Dimensions: Coil diameter from 100mm to 2000mm, tube wall thickness from 0.5mm to 2.0mm, and total length up to 10 meters per coil.
- High Heat Transfer Efficiency: Spiral geometry creates turbulence, enhancing heat transfer coefficient by up to 30% compared to straight tubes.
- Corrosion Resistance: Stainless steel construction withstands acids, alkalis, and chloride environments.
