We have been an effective and reliable partner to our customers, able to adapt to the most diverse market requirements.

The industrial culture and intuition of our founders, together with the performance of our employees, have allowed us to develop this modern chemical platform located in Hernani.

Water and salt chemistry. Thanks to the electrolysis of these two raw materials of great purity we can produce Chlorine, Caustic Soda, Hydrogen and Sodium Chlorate.

Through their usage as a final or intermediate product in other syntheses, they allow us to produce a very high percentage of the goods and products of common use available to society.

Produce your own chlorine

Produce tu propio cloro: Paso 1

Step 1

Add a tablespoon of salt to a glass of water

Produce tu propio cloro: Paso 2

Step 2

Stir until the salt is dissolved

Produce tu propio cloro: Paso 3

Step 3

Make two holes in a piece of cardboard and place two pointed pencils on both ends

Produce tu propio cloro: Paso 4

Step 4

Place the cardboard on top of the glass and dip the pencils in it.

Produce tu propio cloro: Paso 5

Step 5

Connect the pencil ends to a 4.5 volt flask battery for 10 seconds

Produce tu propio cloro: Paso 6

Step 6

Do you recognize the smell? Salt water is transformed into chlorinated water, like that of swimming pools, through electrolysis. ATTENTION: Do not drink the water after the experiment!

We meet the highest requirements for safety, quality and sustainability

Committed to safety, quality and the environment, we are pioneers in integrating the highest environmental requirements.

In 2002, Electroquímica de Hernani was the first Spanish electrolysis to entirely convert its chlorine production to membrane technology.
