The Aefyt recommends an exhaustive control of the water of network

Legionela And high temperatures

In front of the arrival of the summer, the technical commission of Association of Companies of the Cold and his Technologies (Aefyt) believes necessary to insist in the need of not generating social alarm around the equipment of refrigeration evaporativa linking them injustificadamente to the legionela. With a suitable maintenance, satisfied demands the Law, these equipment result safe and his energetic advantages, environingingmental and economic are undoubted.

With the arrival of the summer and the high temperatures can produce a greater concentration of the bacterium of the legionela. A colony virulenta of said bacterium always accesses to any place with some concentration of water through the network, by what the control of his origin is fundamental to avoid the shoots. In this sense, Aefyt recommends an exhaustive control of the water of network that arrives to places so near to the citizens like aspersores, swimming pools or public sources.

Regarding the equipment of cooling evaporativo, Aefyt remembers that they are safe with the maintenance that demands the Royal decree 865/2003, of 4 July, that establishes some simple protocols recommended by all the manufacturers. Besides, from the association does not share the idea that the environingingmental conditions can cause the proliferation of the bacterium still with a correct maintenance.

The towers of refrigeration of water and condensers evaporativos, that use the water like refrigerante, constitute an economic technology, that requires inferior investments to the sued by similar solutions, and favours the energetic saving. In the actuality, the towers of refrigeration of water and condensers evaporativos use in almost all the industrial applications that require refrigeration and calculates that in Europe more than 500.000 industrial installations use these equipment.

The keys of a correct maintenance

The equipment of refrigeration are safe with a correct maintenance. This is like this because so that it produce a shoot of legionela in a team of refrigeration by water and this arrive to the environingingment has to produce a chain of events highly unlikely. These are:

The arrival of a colony virulenta of Legionella Pneumophila through the network of supply of water.
The operation of the team in uncontrolled conditions.
The download of a current of air with microgotas contaminated in suspension, that can arrive until where find people.
A sufficient number of these microgotas are inhaled by susceptible people to contract the illness.

If any one of these links breaks , the possibility of the apparition of a shoot is invalid. To warn the risk of Legionelosis, is sufficient to break this chain of events in any one of the links, existing three of them that is possible to break with a good design and a correct operation of the installation: avoid the conditions that favour the multiplication of bacteria, minimise the drag of aerosols of water in the download of the air of the equipment and reduce the possibilities of inhalation by the people by means of the suitable emplazamiento of the team.
