Alfa Laval semi welded plate heat exchanger
- Semi-welded plate heat exchangers are suitable for refrigeration, chemical processes and various kinds of industrial utility duties.
- The unique Alfa Laval RefTight™ sealing system guarantees a long lifetime sealing between the welded channels because the laser weld is on the outside of the ring gasket groove. The smooth surface ensures a tight uniform seal over the entire gasket ring.
- The Alfa Laval industrial semi-welded line offers a high-efficiency solution with a sealing function combining gaskets and welds. These units can also withstand a higher design pressure compared to fully gasketed plate-and-frame heat exchangers.
- The robust Alfa Laval T10-EW, semi-welded plate industrial heat exchanger with the RefTight™ sealing system offers a higher standard of efficiency and durability to meet higher pressure demands.
- You can order the Alfa Laval Industrial semi-welded line for various temperature programs, pressure drop limitations, media and operating pressures.
- The various sizes in the product line cover a full range of heat transfer capacities and flows. All are carefully designed and selected to achieve optimal performance.
Semi welded heat exchanger contruction
- A plate heat exchanger consists of a pack of corrugated metal plates. Each plate is fitted with a rubber gasket, which seals the channel formed between two adjacent plates.
- In an alternative design, every second gasket is replaced by a laser-weld to allow for fluids aggressive to the gaskets. The plate pack is assembled between a fixed frame plate and a movable pressure plate and compressed by tightening bolts.
- The frame plate and the pressure plate are suspended from an upper carrying bar and guided by a lower guiding bar, both of which are fixed to a support column.
- The size of the unit and the material and number of plates are determined by the requirements of the particular application and duty.
- Each individual plate heat exchanger is optimised for its duty and, as a result, the usage of materials is kept to a minimum.
