Flow-through heaters, indirect heating
Stainless steel direct -flow heaters are used to heat flowing liquids. The heating elements are hard -brazed on the outside of the pipe to avoid direct contact between the liquid and the heating element. Heating elements are dimensioned according to their location and the power required. In general, the power required is between 0.6 kW and 12 kW. These water heaters are used in tempering equipment, sterilising washing machines, bioscience equipment and swimming pools.
