The water in the boiler contains salts, which are built up by the continuous evaporation. If these salts are not eliminated, bubbles
and foam are formed when the density of the water increased.
To prevent these lime deposits forming, the water supply must be suitably treated, with the result that certain salts are changed
producing impurities which form sludge and encrusted deposits which then adhere to the sides or the bottom of the boiler and to the
combustion tubes, together with particles of dirt, remains of electrodes, carbonic acid, oxygen, etc. This leads to a high level of rust
which may:
Destroy the metal plate of the boiler, causing high maintenance costs.
Produce thermic voltages, causing cracks in the metal plate and soldering cord.
Notably slow down thermic transmission, meaning an unnecessary and excessive consumption of fuel.
Nominal pressure: PN-40.
Permitted pressures and temperatures according to DIN-2401. Sheet 2.
Flange connection: DN-25, 32, 40 and 50 (DIN-2545).
Specifications
— A the draining section is opened quickly and completely by driving the lever from right to left. The deposits, collected at the
— bottom of the boiler, are disturbed and sucked up by the sudden air intake which carries them out.
— Direct emptying passage, meaning a high volume and low level of load loss.
— Rotating the lever from left to right causes instant closing, preventing irrevocable losses of water and pressure. .
— Seatings and stoppers treated and balanced ensuring a level of tightness higher than that required by DIN-3230, Sheet 3. .
— Equipped with a screw for the drainage of the sedimentations.
— Simplicity of design ensures good performance.
