Why dry steam air conditioning cleaning and decontamination?

Can steam be used to decontaminate air conditioning systems without using chemicals?

Yes, steam, thanks to its high temperature (up to 180°C at a pressure of 8 bars) and high pressure, kills harmful micro-organisms. However, unlike disinfection using a combination of steam and a disinfectant product, there is no residual effect over time.

The persistence of a product is the length of time it remains active. It can last up to several days, depending on the products used. This concept is very important in disinfection, as it prevents the environment from being conducive to the proliferation of harmful micro-organisms (bacteria, viruses, spores, fungi, etc.). However, if steam cleaning is carried out regularly, the steam will disinfect the surfaces.

Finally, steam alone needs to be applied to all surfaces very regularly, otherwise the lack of residual effect encourages the development of harmful micro-organisms. However, with steam combined with a disinfectant, distance is irrelevant, which is why it can be used for airborne surface disinfection.

Why dry steam air conditioning cleaning and decontamination?

The use of dry steam at 175°C combined with a pressure of 8 bars makes it possible to :

  • Dissolve fats
  • Stripping and removing dirt
  • Destroying micro-organisms

To ensure that the most resistant strains are destroyed, we use a powerful disinfectant 100 % of biological origin, specific to air conditioners, in conjunction with steam. APABIO - hydrogen peroxide-based disinfectant

APABIO - Ecological disinfectant based on hydrogen peroxide and peracetic acid.

APABIO disinfectant 100% ECOLOGICAL,  for air-conditioning decontamination: The total disinfection solution, gentle and non-toxic for people and the environment: 6 points:

Why is air conditioning decontamination important?

Air conditioning provides thermal comfort in buildings, but it is also the source of new health, environmental and economic problems. Lack of or poor maintenance of air-conditioning systems can lead to the emergence of numerous illnesses and excessive energy consumption.

Infectious risks :

" Air conditioning is certainly comfortable, but it needs to be maintained extremely meticulously and seriously, otherwise the frequency of work stoppages due to Building Syndrome will increase. "

(Dr S. Guez - allergique.com/article332.html)

Poor air conditioner maintenance encourages the growth of micro-organisms and disperses them in the air.

4 types of pathology have been identified that can have serious pulmonary consequences:

  • Legionellosis : proliferates in poorly maintained ducts. It causes serious respiratory infections.
  • Mould and fungi : They develop at high humidity levels as a result of inadequate maintenance of air conditioning systems.
  • Allergies : air conditioning can aggravate allergies because the treated air can disperse allergens.
  • Sick Building Syndrome: poor indoor air quality (high concentrations of mould, damp, etc.) can be a source of lung problems.

Over-consumption of energy :

A POORLY MAINTAINED AIR CONDITIONER CONSUMES 30% MORE ENERGY

poorly maintained air conditioning fan

Air conditioning consumes a lot of energy. On average, 5% of electricity is consumed by air conditioning in a commercial building.

Air conditioner manufacturers estimate that 8 grams of dust can lead to energy consumption of 25 to 30% more. Dust also contributes to premature wear and tear on the air conditioner.

Regular maintenance of air conditioners helps companies control their energy costs and ensures that the equipment a longer lifespan.

Air conditioning decontamination is a public health issue!!!!

The technique of deslagging, cleaning and disinfection is perfectly in line with current sustainable development policy. This project has the support of the French National Assembly, which has adopted standards and drafted a bill to require companies to maintain their air conditioning systems.

  • Bill No. 1873 presented to the National Assembly, aimed at regulating the maintenance of air conditioning systems in order to reduce health risks.
  • AFNOR standard 15780, defining cleanliness assessment criteria and cleaning procedures for ventilation and air conditioning systems.
  • Summary of this Standard:
  • This European Standard applies to new and existing ventilation and air conditioning systems and specifies the criteria for assessing cleanliness. The procedures for cleaning these systems, and the validation of the effectiveness of the cleaning, also apply to products complying with EN 1505, EN 1506, EN 13053, EN 13180 and EN 13403, used in air conditioning and ventilation systems for human occupancy, as defined in the scope of CEN/TC 156. This European Standard does not apply to industrial process installations. The cleanliness of ventilation systems is considered important for human comfort and health, energy consumption, system life and for the cleanliness of activities or processes carried out in the ventilation area. Considerations for component replacement as an alternative to cleaning (e.g. in the case of flexible ducts and air filters) are also included. This European Standard specifies the general requirements and procedures necessary to assess and maintain the cleanliness of ducted ventilation, including: classification of cleanliness quality; how to assess the need for cleaning (visual inspection, measurements); frequency of assessments (general guidance); guidance for system inspections in accordance with EN 15239, and EN 15240 where relevant; selection of cleaning method - as part of documentation for acceptance in accordance with EN 12599; how to assess the result of cleaning. This European Standard is a parallel standard to EN 12097, which specifies the requirements for the size, shape and location of access panels for cleaning and technical interventions in ductwork systems.
