Efficient Heat Transfer with Reliable Pressure Resistance

A semi-welded plate heat exchanger is a compact heat transfer solution designed for demanding industrial conditions. By combining welded and gasketed plate structures, it provides efficient heat transfer while offering enhanced resistance to pressure, temperature, and challenging process media.

Compared with conventional heat exchange equipment, the semi-welded design can reduce certain limitations associated with fully gasketed connections. Optimized flow channels also promote better fluid mixing and heat transfer performance, making the unit suitable for applications where efficiency, compactness, and operating reliability are important.

Key Advantages

• Efficient heat transfer –      Optimized plate channels improve fluid turbulence and heat exchange      performance.

• High temperature and pressure capability – The welded plate structure is suitable for demanding      operating conditions.

• Wide media compatibility –      Applicable to water, oil, refrigerants, steam, and selected corrosive      process fluids.

• Compact design – Provides high      heat transfer capacity within a relatively small installation footprint.

• Flexible maintenance – Service      and maintenance options can be selected according to the specific      construction and application.

Compatible Equipment & Systems

Semi-welded plate heat exchangers can be selected according to heat transfer capacity, connection size, design pressure, operating temperature, and process media. Typical applications include:

• Industrial refrigeration and cooling systems

• Heat pump and energy systems

• Hydraulic equipment cooling

• Compressors and power equipment

• Chemical and process industries

• District heating and hot-water systems

• Oil cooling and heat recovery units

Typical Applications

In refrigeration systems, semi-welded plate heat exchangers can serve as evaporators, condensers, or oil coolers. In industrial processes, they can be used for heating, cooling, and heat recovery between different fluids.

For systems involving high-pressure refrigerants or demanding process media, the semi-welded construction provides a practical solution for continuous heat transfer operations. Its compact plate configuration also makes it suitable for equipment where installation space is limited.
