Wide channel plate heat exchanger BW250A

The wide-channel plate heat exchanger and the detachable plate heat exchanger are two common types of plate heat exchangers. They differ significantly in design, application scenarios, and functional characteristics. Here are the main differences between them: 

Flow channel structure design

The wide flow channel plate heat exchanger adopts a wider flow channel gap (usually 5-10mm, much larger than the 2-4mm of ordinary plate heat exchangers), and the plate wave pattern is relatively gentle or adopts special designs (such as point-like protrusions).

Purpose: To avoid blockage and is suitable for high-viscosity, particle-containing or fiber-containing media (such as sludge, slurry, high-viscosity liquids, etc.).

The detachable plate heat exchanger adopts a standard narrow flow channel design (usually 2-4mm), with dense plate wave patterns (such as zigzag, diagonal, etc.), to enhance turbulence and heat transfer efficiency.

Purpose: To optimize heat transfer efficiency and is suitable for clean or low-viscosity media (such as water, steam, oil, etc.). 

Application Scenarios

The wide channel plate heat exchanger is suitable for fluids containing solid particles, fibers, crystals or high viscosity (such as papermaking wastewater, food slurries, chemical sludges, etc.).

The detachable plate heat exchanger is suitable for clean or frequently cleaned fluids (such as air conditioning water systems, boiler steam, hydraulic oil, etc.). 

Maintenance and Disassembly

Wide-channel plate heat exchangers are usually designed for disassembly. However, due to their wide channels, the cleaning requirements may be lower (unless the medium is prone to deposition).

The plates and gaskets of the disassemblable plate heat exchanger can be quickly disassembled, facilitating mechanical cleaning or replacement, and are suitable for scenarios with high fouling risks or strict hygiene standards (such as dairy products, pharmaceuticals).
