Brazed Heat Exchangers
Primary Exchanger Material Aluminium Usage/Application Hydraulic and Industrial Process Sub-coolers Available liquid refrigerants Yes Gases pure vapour and mixtures refrigerant super-heating vapour Evaporators for dry expansion
Copper brazed plate heat exchangers provide efficient heat transfer with a small footprint. They are maintenance free, provide a long service lifetime and can withstand high temperatures and extremely high design pressures. They are used in a range of duties including cooling, heating, evaporation and condensing.
Brazed plate heat exchangers are widely used in refrigeration plants.
Units in the Alfa Laval AC line of copper-brazed heat exchangers are mainly used as:
- Evaporators for dry expansion and cooling water
- Condensers for rejecting or recovering heat to water
- Economizers for cooling liquid refrigerant and super-heating vapour refrigerant.
They can also be used as:
- Sub-coolers to cool liquid refrigerants using well water.
- Intermediate heat exchangers in the absorption cycle, to preheat the diluted solution or to pre-cool the concentrated solution.
