20-plate brazed heat exchanger
With 20 mm diameter hose holder
Brazed plate heat exchanger consisting of a pack of corrugated plates without gaskets, welded together by copper brazing in vacuum furnaces.
Operating principle
Brazed plate heat exchangers are used in a wide variety of fields, from civil applications for the production of domestic hot water, to industrial applications for the cooling of machine tools and in refrigeration as evaporators/condensers.
They operate with parallel flow configurations. The two fluids always circulate in countercurrent in separate circuits. The inlet and outlet positions can be chosen freely by the installer, as long as the counterflow is maintained.
Do not use with aggressive substances (acids, ammonia, sea water) which could corrode the copper used for brazing.
Advantages
High pressures and temperatures: the total absence of gaskets allows extremely high operating pressures and temperatures to be reached.
Compact size: the integration of the containment frame on the plate pack during the brazing process allows for high heat exchange with very small dimensions.

CLEANING AND SANITIZATION
For cleaning/detergent, it is recommended to intervene immediately after use, to prevent the must residues from drying and encrusting on the walls and internal spaces of the exchanger:
- rinse with water, preferably warm
- circulate a solution of warm water and alkaline soap (soda-based) to descale, such asneodersol glass
- rinse with water
- store the exchanger in a clean and dry place
For sanitization, (to be carried out before next use):
- circulate a solution of water and peracetic acid for 15', if the solution is diluted at 3x1000 (3ml x litre) there is no need to rinse, but if the solution is more concentrated, rinse with clean water. Caution: During this phase, it is recommended to always use gloves, glasses and a mask.
- now the exchanger is ready to be used again.
