As a trusted manufacturer from Anping County Boli Hardware Wiremesh Products Factory, established in 1998 with an annual export turnover of US$5-10 million, we are proud to introduce our Dimpled Plate Heat Exchanger for Chemical Processing, crafted from premium 304 Stainless Steel and fitted with durable NBR gaskets. This heat exchanger is designed to deliver exceptional thermal efficiency, corrosion resistance, and long service life in demanding chemical environments. With over two decades of expertise in metal fabrication, our factory ensures every unit meets rigorous quality standards, making it a reliable choice for global chemical plants, refineries, and processing facilities.
Our dimpled plate design creates a unique flow pattern that maximizes heat transfer while minimizing pressure drop. The 304 stainless steel plates offer excellent resistance to a wide range of chemicals, acids, and alkalis, while the NBR gaskets provide a tight seal against leaks and withstand temperatures up to 120°C. This combination makes our heat exchanger ideal for tasks such as heating, cooling, condensation, and evaporation in chemical processing lines.
We understand that every chemical process has unique requirements—that's why our heat exchangers are fully customizable in terms of plate count, connection type, and overall dimensions. Whether you need a compact unit for a pilot plant or a large-scale system for continuous production, we can deliver a solution tailored to your specifications.
Key Features & Advantages
- High Thermal Efficiency: The dimpled plate pattern induces turbulence, enhancing heat transfer coefficients up to 3-5 times higher than traditional shell-and-tube exchangers.
- Corrosion Resistance: 304 stainless steel plates resist pitting, crevice corrosion, and stress corrosion cracking in chemical environments.
- Robust Sealing: NBR gaskets provide excellent oil and chemical resistance, with a temperature range of -20°C to 120°C.
- Compact & Lightweight: Up to 80% smaller footprint compared to shell-and-tube designs, saving valuable floor space.
- Easy Maintenance: Plate stack can be easily disassembled for cleaning, inspection, or replacement of individual plates and gaskets.
- Low Fouling: Smooth, dimpled surfaces reduce deposit buildup, extending intervals between cleaning.
- Adaptable Connection: Available with flanged, threaded, or custom connection options to integrate seamlessly into existing piping.
- Pressure Rating: Designed for working pressures up to 1.0 MPa (higher ratings available on request).

Frequently Asked Questions
-
Q: What is the maximum operating temperature for NBR gaskets?
A: NBR gaskets can handle continuous temperatures up to 120°C. For higher temperature applications, we can recommend alternative gasket materials such as EPDM or Viton (available upon request). -
Q: Can I use this heat exchanger for corrosive chemicals like hydrochloric acid?
A: 304 stainless steel offers good resistance to many acids, but for highly corrosive media like hydrochloric acid, we recommend evaluating the specific concentration and temperature. Please provide your process details for a material compatibility review. -
Q: How do I clean the dimpled plates?
A: The plate stack can be easily disassembled by loosening the compression bolts. Each plate can be cleaned manually with a soft brush and mild detergent, or using chemical cleaning-in-place (CIP) methods. -
Q: Is the heat exchanger available in single-pass or multi-pass configurations?
A: Yes, we offer both single-pass and multi-pass arrangements. The choice depends on your required temperature change and flow rates. Our engineers can help design the optimal pass arrangement. -
Q: What are the standard connection types?
A: Common connections include threaded (NPT/BSP) and flanged (ANSI/DIN). We also provide custom connections upon request. -
Q: Can I order a heat exchanger with a different number of plates?
A: Absolutely. The plate count is customizable to meet your heat transfer surface area requirements. Simply provide your specifications, and we will configure the unit accordingly. -
Q: Do you provide drawings or technical documentation?
A: Yes, we provide dimensional drawings, P&ID schematics, and performance curves for each custom order. Contact our sales team for details. -
Q: What is the typical lead time for a custom unit?
A: Lead time depends on complexity and quantity. Standard configurations can ship within 2-4 weeks, while custom units may require 4-8 weeks. We offer expedited options for urgent orders.
