Industrial Semi-Welded Li...

Product Description

Alfa Laval Industrial semi-welded line is used when gaskets are not suitable for one of the process media. Also, the semi-welded line can take a higher design pressure compared to fully gasketed plate.

The Alfa Laval semi-welded gasketed plate-and-frame heat exchangers are available in six models, M6-MW, M10-BW, MK15-BW, MA30, T20 and TK20. The refrigerant flows in laser-welded, sealed plate channels, and the brine in gasketed channels. The flexible modular design copes with fatigue stresses and ice formation. The semi-welded heat exchanger handles most refrigerants on the welded side and is particularly suitable for ammonia duties. Standard plate materials are stainless steel and titanium. Temperature range is -47°C to 150°C; pressure is up to 63 bar, depending on size.

Benifits of the Industrial semi-welded line

  • Low charge
  • Low weight
  • Easy to modify heat transfer area for altered capacities, refrigerants
  • Easy inspection and cleaning of the liquid side
  • Reliable, with long service life for heavy duties
  • Plate materials for corrosive fluids, cooling water and brines
  • Condenser/desuperheater or condenser/oil cooler combined in single unit
  • Floating condensation with flooded evaporation
  • Can be optimized with air liquid coolers in indirect cooling systems

Applications for Industrial semi-welded line

  • Water/glycol-cooled condensers
  • Flooded evaporators
  • DX evaporators
  • Cascade systems
  • Desuperheater/gas coolers for, for example, heat recovery
  • Economizers/subcoolers
  • Oil coolers
