Anping County Boli Hardware Wiremesh Products Factory proudly presents our Pillow Plate Heat Exchanger Equipment with a 3-6mm adjustable plate gap, constructed from premium 304 stainless steel and manufactured in full compliance with ASME standards. Since 1998, we have been a trusted manufacturer in the heat exchange industry, exporting to over 20 countries across North America, South America, Europe, Asia, and Africa. Our annual export value of US$5–10 million reflects our commitment to quality and global customer satisfaction. This pillow plate heat exchanger is designed for efficient heat transfer in demanding industrial applications, offering exceptional corrosion resistance, robust construction, and flexible customization to meet your specific process requirements.
Product Overview
The pillow plate heat exchanger (also known as dimple plate or embossed plate heat exchanger) features a unique structure where two metal plates are welded together and then inflated to create a pillow-like pattern. This design creates a series of flow channels that significantly enhance turbulence and heat transfer efficiency. The 3-6mm plate gap is adjustable during manufacturing, allowing you to optimize the exchanger for different fluid viscosities, flow rates, and pressure drops. Made from 304 stainless steel, the unit is suitable for clean, corrosive, or food-grade media. It is widely used in pasteurization, chemical heating/cooling, pharmaceutical processing, HVAC systems, and industrial water treatment.
Key Features and Benefits
- High Heat Transfer Efficiency: The pillow plate geometry creates turbulent flow, increasing the heat transfer coefficient by up to 30% compared to conventional plate heat exchangers.
- Compact and Lightweight Design: The all-welded construction eliminates gaskets, reducing weight and footprint, while maintaining high pressure capability.
- Corrosion Resistance: 304 stainless steel provides excellent resistance to most organic acids, alkalis, and chlorides, extending service life in aggressive environments.
- Adjustable Plate Gap (3-6mm): Customizable gap allows handling of fluids with suspended solids or high viscosity without clogging, and optimizes thermal performance.
- ASME Standard Compliance: Every unit is designed, fabricated, and tested in accordance with ASME Boiler and Pressure Vessel Code, ensuring safety and reliability.
- Easy Maintenance and Cleaning: The smooth pillow plate surface minimizes fouling, and the unit can be cleaned in place (CIP) or disassembled for manual cleaning if required.
- Customizable Configurations: Available in single-pass, multi-pass, or multi-section designs; port sizes, nozzle orientations, and mounting brackets can be tailored to your system.

Frequently Asked Questions
Q1: What fluids can be used with this pillow plate heat exchanger?
A: The 304 stainless steel construction is compatible with water, oils, organic solvents, mild acids, alkalis, and food-grade liquids (e.g., milk, juice, beer). For highly corrosive media (e.g., strong chlorides), we recommend 316L or duplex stainless steel options.
Q2: Is the plate gap adjustable after manufacturing?
A: No, the plate gap is fixed during the welding and inflation process. However, we can produce different gap sizes (3-6mm or custom) based on your application requirements before manufacturing.
Q3: Can this heat exchanger handle high-pressure applications?
A: Yes, the design pressure can be customized up to 2.5 MPa. Our standard units are rated for 1.0 MPa, but we can strengthen the plate thickness and weld design to meet higher pressure demands while maintaining ASME compliance.
Q4: How do I clean the pillow plate heat exchanger?
A: The smooth surface resists fouling, and CIP (Clean-in-Place) circuits can be designed into the system. For heavy fouling, the unit can be opened by removing the end covers (if designed as serviceable) or flushed with appropriate cleaning agents. We provide cleaning guidelines with each shipment.
Q5: What is the typical lifespan of this heat exchanger?
A: With proper operation and maintenance, a 304 stainless steel pillow plate heat exchanger can last 10-15 years or more, depending on the corrosiveness of the fluid and operating conditions. We recommend periodic inspection of welds and pressure testing.
Q6: Do you offer custom sizes or special connections?
A: Absolutely. We can customize the length, width, number of plates, port sizes (flanged, threaded, tri-clamp), and mounting brackets. Please provide your process parameters, and our engineering team will design a solution.
Q7: Is the heat exchanger certified for food contact?
A: 304 stainless steel is food-grade material and meets FDA and EU regulations for food contact surfaces. We can also supply with sanitary polish finish (Ra ≤ 0.8 μm) upon request.
Q8: What is the minimum order quantity (MOQ)?
A: For standard models, MOQ is 1 unit. For custom designs, MOQ may be 2-5 units depending on complexity. We are flexible and welcome small trial orders for new customers.
