treatment system

for ductless Hood

An activated carbon control unit is not sufficient for a system without a chimney.

When we talk about a ductless hood, we must specify that it's a treatment system and not just one product.


For this reason, a series of objective variables, legal obligations and necessary information must be taken into account.


Our plants are certified according to the law and with demonstrable results in various activities in Italy and abroad.







Let's analyze and make a reflection.


In order to create a kitchen where there is no possibility to have a flue, you need the authorization of the AUSL,

which must issue an exemption to be able to exercise with a kitchen without a flue.

(applying a corrected European law in Italy).


The AUSLs are not obliged but they grant the derogation only after being convinced that the treatment with the air treatment systems, vapors, fumes, smells are effective and above all that will be done with machines that guarantee an almost absolute treatment.



All equipment under the hood must be electric, (mandatory) unless otherwise specified and with AUSL authorizations.

It is imperative that the outside air is discharged (for volumes of a certain importance) and the kitchen areas must have an air change in accordance with the law.

For this reason it is advisable for the customer who contacts us to provide us with a layout of the room to be treated or in the absence of a layout, an approximate hand sketch at the outset.

Let's take an example ...


An approximate example could be:


Fryer 70 cm

Frytop 80 cm

Kitchen 90 cm

Oven 90 cm


With these measures, the hob will have a width of 330 cm.

We will have to determine the size of the hood.


Hob plus 30 cm free for each side, the dimensions of the hood become 390 cm x 120 cm x 55 cm. With a speed under the hood of 0.5 m/s or 8500.00 mc/h.

Let's do some calculations;


For the treatment with a hood without a flue, we use our technology and our experience.


  • 10,000.00 mc/h activated carbon control unit (20% more recommended)


  • Ozone generators for the treatment of odors with production capacity 2 x 70 g/h, 140g O3 per hour.


  • Smoke treatment system with electrostatic systems.


  • Finally, the introduction of air inside the system for a compensation of 4200 mc / h

This system can compensate the expense within 3-4 years as it requires neither heating nor cooling, with an electric saving of about 12kw / hour for heating.


The system proposed in the example can naturally be resized according to your needs, reducing the size of the hob. This reduces the maximum air flow rate.


As you understand it is not a single product but a complex system of multiple components.


This system was set up after more than ten years of research and experimentation by our technical and production staff.




Contact us with confidence and we will find together the best solution for your needs.
