Welcome to Anping County Boli Hardware Wiremesh Products Factory, a trusted manufacturer since 1998 with over two decades of metal fabrication expertise. Our Custom 304 Stainless Steel High-efficiency Pillow-type Heat Recovery Exchanger is designed for demanding industrial applications requiring reliable heat transfer at 10 Bar pressure. Combining robust construction with advanced pillow-plate technology, this exchanger offers superior thermal performance and corrosion resistance, making it an ideal choice for heat recovery systems worldwide.
Crafted from premium 304 stainless steel, our pillow-type heat exchanger features a unique embossed pattern that creates turbulent flow, enhancing heat transfer efficiency while maintaining a compact footprint. Each unit is engineered to meet your specific requirements — from custom port sizes to tailored pressure ratings — ensuring seamless integration into your existing process. Whether you need to recover waste heat from exhaust gases, preheat fluids, or maintain precise temperature control, our exchanger delivers reliable results.
With annual export values exceeding US$5 million and a global footprint spanning North America, Europe, Asia, and beyond, we are committed to quality and customer satisfaction. Every heat exchanger undergoes rigorous testing to guarantee performance under 10 Bar pressure, and our flexible customization options allow you to optimize your system's efficiency.
Key Features
- High-Efficiency Heat Transfer: Pillow-plate geometry induces turbulent flow, increasing heat transfer coefficient by up to 30% compared to smooth plates.
- 10 Bar Pressure Rating: Designed and tested for safe operation at 10 bar (145 psi) with a safety factor, suitable for medium-pressure applications.
- 304 Stainless Steel Construction: Excellent corrosion resistance against water, steam, mild chemicals, and atmospheric conditions, ensuring long service life.
- Customizable Design: Available in various sizes, thicknesses, port configurations, and surface finishes (2B, brushed, or bright annealed).
- Compact & Lightweight: Pillow-type structure reduces material usage while maintaining high strength, saving space and weight in your system.
- Easy Maintenance: Smooth internal surfaces minimize fouling and are easy to clean; optional access ports for inspection.
Technical Specifications
| Material | 304 Stainless Steel (1.4301) |
| Max Working Pressure | 10 Bar (145 psi) |
| Design Temperature Range | -20°C to 200°C (depending on gasket and application) |
| Plate Thickness | 0.8 mm – 1.5 mm (customizable) |

Frequently Asked Questions
-
Q: What is the maximum temperature this exchanger can handle?
A: The recommended operating temperature range is -20°C to 200°C, depending on the gasket material and process fluid. For higher temperatures, we can customize with alternative gaskets or welding. -
Q: Can I get a sample before bulk order?
A: Yes, we offer sample units for evaluation. The sample cost and shipping can be arranged. Typically, sample delivery takes 10–15 working days after design confirmation. -
Q: How do you ensure the exchanger can withstand 10 bar pressure?
A: Each unit is hydrostatically tested at 1.5 times the design pressure (15 bar) to verify integrity. Our welding procedures are qualified, and materials have mill certificates available upon request. -
Q: What sizes are available?
A: We can produce custom sizes from small (e.g., 200mm x 200mm) up to large (e.g., 2000mm x 1000mm). The thickness and number of pillow plates can be adjusted to meet your heat transfer requirements. -
Q: Is this product suitable for food-grade applications?
A: Yes, 304 stainless steel is food-grade. We can supply with a surface finish (Ra ≤ 0.8 μm) and sanitary tri-clamp connections for food, dairy, and pharmaceutical use. -
Q: Do you provide technical drawings?
A: Yes, we will provide 2D/3D drawings for your approval before production. Custom modifications are welcome. -
Q: What is the minimum order quantity?
A: MOQ is 1 piece for custom orders. For standard sizes, we can accommodate small quantities. Please contact us for details. -
Q: How do I clean the exchanger?
A: The smooth internal surfaces allow easy cleaning with CIP (clean-in-place) systems. For heavy fouling, chemical cleaning or mechanical brushing is possible. Our design can include removable covers for access.
