Double-layer Coil Evaporator for Steam Cooling, 316L Stainless Steel, DN50 Connection, 0.5t/h Flow Rate
Product Spotlights
Welcome to Anping County Boli Hardware Wiremesh Products Factory (established 1998), a trusted manufacturer with over 25 years of experience in precision metal fabrication. Our Double-layer Coil Evaporator for Steam Cooling is engineered to deliver superior heat transfer efficiency in demanding industrial applications. Crafted from high-grade 316L stainless steel and featuring a DN50 connection with a 0.5 t/h flow rate, this evaporator is designed to reliably cool steam while resisting corrosion and thermal stress. Whether you need a standard unit or a customized solution, our factory-direct approach ensures competitive pricing and fast turnaround.
Product Characteristics & Technical Specifications
- Double-layer Coil Design: The dual-layer configuration maximizes the heat exchange surface area, allowing for efficient steam condensation and cooling within a compact footprint. This design reduces the required installation space while improving overall thermal performance.
- Premium 316L Stainless Steel: 316L grade offers excellent resistance to chloride-induced corrosion, pitting, and stress cracking, making it ideal for cooling steam that may contain corrosive impurities or operate in harsh environments. The low carbon content also enhances weldability and longevity.
- DN50 Standard Connection: Equipped with a DN50 (2-inch) inlet/outlet connection, this evaporator easily integrates into existing piping systems using flanges or threaded fittings. The connection size is widely used in industrial steam loops, ensuring compatibility with most installations.
- 0.5 t/h Flow Capacity: Rated for a nominal flow rate of 0.5 tons per hour, this unit is suitable for medium-scale steam cooling applications, including process cooling, HVAC systems, and chemical processing. The flow rate can be adjusted within a range (consult factory for specifics).
- Corrosion & Heat Resistance: 316L stainless steel maintains its mechanical properties at elevated temperatures, and the polished surface finish (optional pickling/passivation) reduces fouling and facilitates cleaning, extending service life.
- Customizable Additional Features: Options such as alternative connection sizes, additional pressure ratings, and specialized surface treatments are available upon request. Our engineering team can adapt the design to meet your unique process requirements.

Key Advantages for Your Business
- Enhanced Heat Transfer: The double-layer coil creates a longer path for the steam, increasing contact time with the cooling medium (e.g., water or refrigerant). This results in more efficient condensation and lower outlet temperatures.
- Durability in Harsh Conditions: 316L stainless steel withstands steam, condensate, and chemical cleaning agents without degradation. The robust construction reduces maintenance costs and downtime.
- Easy Integration: Standard DN50 connections simplify installation into existing pipelines. The compact design fits into tight spaces, saving valuable floor area.
- Flexible Customization: We can modify the coil diameter, connection orientation, and pressure rating to match your specific system. Our in-house engineering team provides free technical consultations.
- Factory Direct Pricing: As a manufacturer, we eliminate middlemen, offering you cost-effective solutions without compromising quality.

Frequently Asked Questions (FAQ)
-
Q: What is the main application of this double-layer coil evaporator?
A: It is primarily used for cooling steam in industrial processes, such as condensing steam in heat recovery systems, HVAC, food processing, and chemical plants. The 316L stainless steel construction makes it suitable for corrosive or high-purity applications. -
Q: Can the connection size be changed from DN50?
A: Yes, we offer custom connection sizes upon request. Please provide your required dimensions, and our engineering team will adapt the design accordingly. -
Q: What is the maximum working pressure and temperature?
A: The standard design handles up to 16 bar pressure and temperatures from -20°C to 250°C. For higher pressures or temperatures, we can customize the coil thickness and weld specifications. -
Q: Is the evaporator suitable for cooling media other than water?
A: Yes, the 316L stainless steel material is compatible with many coolants, including glycol mixtures, brine, and refrigerants. However, please confirm compatibility with our technical team for your specific fluid. -
Q: How long is the lead time for a standard unit?
A: For standard models (DN50, 0.5 t/h), lead time is typically 15–20 working days. Custom orders may require additional time depending on complexity. We can expedite for urgent projects. -
Q: Do you provide certification or material test reports?
A: Yes, we can issue a Mill Test Certificate (MTC) for the 316L stainless steel material upon request. Other certifications (e.g., pressure vessel compliance) are available as per your requirements. -
Q: What is the minimum order quantity (MOQ)?
A: MOQ is 1 unit for standard models. For custom designs, minimum quantity may vary, but we are flexible for sample orders. -
Q: How does the double-layer design improve performance compared to a single-layer coil?
A: The double-layer configuration provides approximately 40–60% more heat transfer surface area within the same footprint, leading to faster steam cooling and higher efficiency. It also helps achieve a more uniform temperature distribution.
