Industrial semi-welded line
Alfa Laval provides an extensive range of industrial semi-welded plate heat exchangers, designed for handling liquids and gases that are incompatible with standard gaskets or require operation at higher pressures. These heat exchangers are widely used in refrigeration applications, particularly for the evaporation and condensation of ammonia and CO2 for their exceptional resistance to ice formation and fatigue stresses caused by pressure and temperature fluctuations.
Highly efficient and flexible
- Space-saving compact unit
- Low operating cost possible owing to superior energy efficiency and prolonged service intervals
- Safe and reliable sealing with no risk of cross-contamination
- Pressure and temperature fatigue resistant
Performs under pressure
Semi-welded heat exchangers offer superior efficiency, cost-effectiveness, and flexibility over shell-and-tube heat exchangers, making them a preferred choice in many industrial applications.
- Compact and Space-Saving: Semi-welded heat exchangers are significantly smaller and lighter compared to shell-and-tube heat exchangers, making them ideal for installations with limited space. Their modular design also allows for easy expansion or modification to meet changing thermal requirements
- Easier Maintenance and Flexibility: While the welded sections provide durability, the gasketed side allows for easier cleaning, inspection, and plate replacement. This combination ensures long-term reliability and reduces downtime.
- Energy Efficiency and Cost Savings: Semi-welded heat exchangers are designed to minimize energy consumption and operational costs. Their high heat transfer efficiency and compact design reduce both initial and ongoing expenses, including pump power and maintenance costs.
