Heat Exchangers

Piece of equipment for transferring heat from one heat-carrying medium flowing on the primary side of the exchanger to another heat-carrying medium flowing on the secondary side of the exchanger.

One side of the exchanger, i.e. the piping side, is characterized by substantially higher hydraulic resistance than the other side – the shell side. Whilst piping is generally found on the primary side, the secondary side of the exchanger is normally in the shell.

Following types are available:

• water-water
• steam-water
• steam-black oil
• steam-crude oil
• steam-oil
• water-oil
• natural gas-water

They are moreover used in even further media, particularly in chemical industry.

Heat exchangers are primarily intended for central heating systems and for hot water production through forced circulation, where the flow rate is high enough to allow for turbulent flow. They may be used in heavy power industry, in food processing, chemical, pharmaceutical, textile, and construction industry – given its good resistance against wear, organic acids, fats, fruit juices, soap solutions, etc.

Plate Heat Exchangers

Specifically designed for industry and hygienic types for food, dairy, brewing and pharmaceutical industries.

Gasket types as brazed types are available.
