Wide Gap Plate Heat Exchangers for Difficult Fluids

Our wide gap plate heat exchangers are engineered to handle coarse particles and high-viscosity fluids without compromising efficiency.

Key Advantages:

The special plate geometry allows fibers and solids to pass freely through the heat exchanger, ensuring uninterrupted operation even in demanding applications.

Industrial Applications

Wide gap plate heat exchangers are commonly used in industries where conventional heat exchangers struggle:

Sugar and distillery processes

Pulp and paper industry

Bioethanol and fermentation plants

Petrochemical and chemical processes

Wastewater and sludge heating

Heat recovery systems

Each unit is customized based on fluid characteristics, flow rate, and operating temperature to ensure reliable long-term performance.

Materials & Construction

SRJ wide gap plate heat exchangers are built using robust, industrial-grade materials for long service life:

  • Plate materials: Stainless steel, titanium, special alloys
  • Plate design: Wide gap geometry for fibrous media
  • Gasket materials: EPDM, NBR, FKM (Viton)
  • Frame materials: Heavy-duty carbon steel or stainless steel

This construction ensures durability, corrosion resistance, and easy maintenance even in highly fouling applications.

Why Choose a Wide Gap Plate Heat Exchanger?

A wide gap plate heat exchanger is the ideal solution for processes involving fibers, solids, or viscous fluids where traditional plate heat exchangers fail.

Its design reduces clogging, minimizes downtime, and ensures consistent heat transfer performance — making it a cost-effective and reliable choice for complex industrial processes.

Frequently Asked Questions

A wide gap plate heat exchanger is a heat transfer solution specially designed for fluids that contain fibres, solids, pulp, or high viscosity materials. The wide spacing between plates allows these fluids to flow freely without clogging, ensuring stable performance and reduced fouling in demanding industrial processes.

A wide gap heat exchanger differs from conventional designs by using plates with larger channel spacing. This reduces blockage, pressure drop, and cleaning frequency when handling slurries, fibrous media, or particulate fluids, making it ideal for difficult process conditions.

Wide gap plate heat exchangers are widely used in sugar processing, pulp and paper, wastewater treatment, bioenergy plants, food processing, and chemical industries. These sectors benefit from reliable heat transfer performance even when working with non-Newtonian or fouling fluids.

Yes, wide gap plate heat exchangers are designed for easy inspection and cleaning. The open plate channels minimize fouling, while the gasketed construction allows quick disassembly, reducing downtime and maintenance costs in continuous industrial operations.

A wide gap plate heat exchanger should be selected when the process fluid contains fibres, suspended solids, or has a high tendency to foul. It is the preferred solution for applications where conventional heat exchangers struggle with clogging, pressure drop, or frequent cleaning requirements.
