What is descaler made of?
Descaling agents are typically acidic compounds such as hydrochloric acid that react with the calcium carbonate and magnesium carbonate compounds present in the scale, producing carbon dioxide gas and a soluble salt.
Why descaling is required?
Descaling is needed when a heat exchanger accumulates a significant thickness of calcium on its surface, enough to insulate the water from the heat source and impair performance Periodic descaling of industrial heat exchangers’ tubes is necessary to inhibit corrosion and improve efficiency.
How do you make an espresso scale?
Position the portafilter, start extraction, place espresso cup(s) on the scales and tare (zero) the scales (do this in a fluid movement and the scales will be zeroed before the shot comes through).

Why does scaling happen?
Scaling occurs when water has high levels of minerals like calcium carbonate, which can build-up on surfaces Slight scaling can be considered beneficial in that the inside surfaces of metal pipes become coated with harmless minerals that act as a barrier to corrosion.
What does water scaling look like?
Shower, Sinks & Surfaces You can often see white spots or a white film on shower doors, sinks, tubs and other heavy water usage areas – especially water that’s heated. Similar to the spots on glassware, these spots are caused by hardness minerals that are left behind when water evaporates.
How do you avoid scale formation?
- Boiler Water Treatment: Scaling is caused by the presence of insoluble salts, calcium, and magnesium in the feed water
- Water Softeners: Installing water softeners can help in preventing limescale in the steam boiler.
