Clean Kitchen Air – CKA Systems

Clean Kitchen Air – CKA Systems

Kitchen exhaust air odour-free and increased fire protection through the prevention of fat deposits by integrating a CKA system into the hood – as near as possible to the point of outbreak – or alternatively in the channel body

    The Advantages of UV Ventilation Hoods and Duct Units:

    • Reducing odors by 95%
    • Reducing odors by 99% when used with a catalytic converter (downstream)
    • Preventing deposits inside ventilation hoods and soot in the exhaust ducts
    • Significantly lowering the risk of fire
    • Lowering maintenance and repair costs for the secondary system’s components
    • The option of reusing kitchen exhaust for heat recovery

    A kitchen is a place where a lot of air pollution is generated. These mainly include moisture, but also products of gas combustion. What to do to prevent the spread of various cooking smells throughout the apartment? Make sure the kitchen is properly ventilated. The CKA system integrated into the hood not only removes the exhaust air from the cook room. It prevents greasy deposits and provides increased fire protection in the apartment.

    Air Exchange in the Kitchen

    Ventilation is a process that involves air exchange – used air is removed from the building and fresh air supplied from the outside. There is natural ventilation and mechanical ventilation (forced by fans or ventilation devices).

    International standards define the airflow values for which a kitchen exhaust air system is needed:

    • Gas or coal stove with an exhaust volume of at least 70 m³/h. It is assumed that the kitchen window is not completely sealed and will open to facilitate ventilation.
    • An electric stove with an exhaust volume of 30 m³/h in a dwelling for up to 3 people with a kitchen window. An electric stove with an exhaust volume of 50 m³/h – for up to 5 people.
    • In an apartment without a kitchen window with an electric stove of 50 m³/h.

    Natural Air System

    Cooking odors and impurities are removed through an exhaust duct with a ventilation grill. It is also in the kitchen. The ventilation grille should not obstruct the outflow of air from the outside. So it is better to give up protection against insects in the form of a mesh. Fresh air flows into the kitchen through the window (if available). It also moves from the rooms where windows should be unsealed or ventilators installed.

    Mechanical Exhaust System

    Natural ventilation is characterized by quite large fluctuations resulting from weather conditions. To ventilate the kitchen properly, it is advisable to install a cooker hood or absorber.

    Kitchen Hood

    The hood circulates the air in the room. It will correctly fulfill its task if it is connected to a separate exhaust grille. Thus, nothing will interfere with the gravity ventilation exhaust system. Another solution is to lead the channel through the wall and end it with a grate. This can be a simple metal grill or an electronic valve. It opens when the user activates the hood.

    Is the hood connected to the only ventilation duct in the kitchen? The ventilation works only when the hood is running.

    The hood efficiency should be adjusted to the size of the kitchen. It is recommended that the air in the room should be changed six times per hour. We will find the required capacity by multiplying the kitchen volume by six. The volume of the kitchen is the floor area multiplied by the height.


    If there are no two independent exhaust grilles in the kitchen, choose a closed-circuit model – the absorber. Unlike the hood, the absorber works in a closed mode, i.e. without removing the air out. The air is purified by a specially developed system of carbon filters that separate dirt particles. The air then returns to the kitchen. The only difficulty is that when using the absorber, the filters must be changed systematically. Activated carbon is quickly used up and the filter becomes useless. The absorber is a solution recommended also in buildings with general channels.

    Air CKA

    We use different types of food processing to create culinary masterpieces. Guests do not know the secrets of cooking and the risks associated with it. Cooking, frying, and baking create streams of smoke containing a spectrum of harmful substances. They accumulate on the walls of the “kitchen trachea” to create problems shortly. How can you prevent them?

    Clean kitchen exhaust air is a very effective and economical technology used in the home and foodservice industry. Organic matter can accumulate, which often causes a fire. Greasy deposits clog the exhaust system and give off unpleasant odors. Fatty fumes are neutralized by cold oxidation. For this, a special grease filter is used, made in the form of a spiral.

    Bad smell and fire risk are not the only problems that housewives and food service workers face. Harsh chemicals are harmful to health since they are not neutralized in conventional hoods. Thus, clogged air ducts create difficulties not only for ventilation ducts but also for people.

    If you constantly inhale an unpleasant smell, sooner or later it will affect the lungs. The trachea, like the air duct, gradually collects aggressive dirt and grease on its walls. If you love to whirl around a stove, you will soon encounter both of these problems. Poor extraction is often the cause of lung disease. In addition to treatment, you will have to deal with cleaning the airway systems. The risk of fat burning is especially true for older ones.

    Safety for Health and Cook Room

    UV-C ozone kitchen exhaust system effectively solves all these problems. Using the technologies that our company offers, you will keep your health and safety of kitchen air ducts. This is true for buildings of historical value. Why endanger yourself and others when there is a simple and effective solution?

    Take advantage of UV ventilation and ducting:

    • reduced odors by 95%;
    • the catalytic converter gives almost 100% elimination of unpleasant odors at the output;
    • elimination of organic deposits and soot on the walls of the hood and air ducts;
    • increasing fire safety;
    • reducing the cost of repair and maintenance of exhaust equipment;
    • efficient use of the heat generated by the stove.

    Our company deals with all aspects of exhaust air using the most advanced technology. We create solutions for household and industrial systems related to waste disposal and neutralization. For each client, we have an individual approach to his problem.
