What is the White Coating that Protect the Coloured Lead

STAEDTLER was the first manufacturer to develop a coloured pencil lead with the Anti-Break-System (or A•B•S for short), especially designed for the special needs of children.

The richly coloured, highquality lead core in our coloured pencils with A•B•S is surrounded by a unique white protective coating. It is so hard and resistant that the break-resistance of the coloured lead is increased by up to 50%, making the pencil up to 30% stronger.

The principle of this protective coating follows a clever example from nature: just like a robust bamboo cane, the white protective coating protects the lead core where it most effective – from the outside – and additionally strengthens the bond between the lead and wood in the pencil.

The advantages are obvious: pencils with A•B•S no longer break as quickly, don’t have to be resharpened as often, and thus have a longer lifespan which ultimately benefits our environment as well.

What we can found near our School & IPDA : Cooling Tower

How Does a Cooling Tower Work?

Warm water from the heat source is pumped to the water distribution system at the top of the cooling tower. The water is distributed over the wet deck fill by means of nozzles. Simultaneously, air is drawn through air inlet louvers and through the wet deck surface causing a small portion of the water to evaporate. The  process of evaporation removes heat from the water. The warm moist air is drawn out of the top of the tower through a natural draft or mechanical cooling tower fans controlled by gearboxes. The resulting cold water is then recirculated back through the heat source in a continuous cycle.
