Our promises

Handling, processing, production, and inspection operations carried out on production sites generate specific pollution, originating from thermal, mechanical, chemical, or nuclear sources.

 

These aerosols can be of various types:

 

  • Particulate: wood dust, flour, metals, glass and carbon fibres, crystalline silica, lead
  • Fumes: welding, chemical reactions, thermal stripping, laser processes
  • Gaseous: acids, cyanides, VOCs, Chromium VI
  • Liquid: oil mist, vapours, paint aerosols
  • Odours : perfumes, chemical reactions
  • Production waste: paper, cardboard, wood, plastic, metals…

These pollutants disperse into the work environment or the atmosphere, exposing operators, surrounding areas, and production equipment to atmospheric or thermal pollution risks.

 

Our missions take shape at every stage, from study to implementation, from cost assessments to planning, training, and monitoring installations. We make every effort to uphold five key principles, working together to build the industrial solutions of tomorrow while safeguarding operator health and atmospheric emissions.

Schéma expliquant les effets des aérosols sur l'homme

Industrial dust has harmful effects on humans: gases are toxic, irritating, and corrosive, and can even cause asphyxiation. Dust particles are toxic, fibrogenic, or pathogenic and can overload the lungs. Operators exposed to aerosols or pollutants risk developing occupational diseases such as skin disorders, poisoning, rhinitis, asthma, and even cancer.

 

The European Union has established the concept of an Occupational Exposure Limit Value for various aerosols under Directive 98/24/EC, dated 7 April 1998. For example, the Average Exposure Value for non-specific dust is set at 10 mg/m³ for the inhalable fraction and 5 mg/m³ for the alveolar fraction. The concentration of asbestos fibres must not exceed 10 fibres per litre of inhaled air over an eight-hour period, while some chemical compounds are limited to just a few µg/m³.

 

Certain aerosols are also classified as CMR – Carcinogenic, Mutagenic, and Reprotoxic, meaning human exposure is strictly regulated. Additionally, the Nuclear Safety Authority (ASN) sets a maximum exposure limit of 20 mSv/year for radioactive substances.

 

WATTOHM actively works to reduce human exposure to chemical agents by extracting pollutants at the source or implementing general building ventilation systems to limit concentrations.

Several studies show that thermal environments degrade working conditions and affect productivity.

 

The ventilation solutions implemented by WATTOHM aim to limit exposure to heat or cold by extracting hot sources and supplying tempered air to workstations.

 

Our ventilation systems also help remove sources of humidity, regulate relative humidity levels, and eliminate unpleasant odours.

Pollutants released during manufacturing operations disperse into the work environment, settling or condensing on machinery, floors, and industrial building structures. Dust can interfere with the functioning of electronic sensors, aerosols contaminate floors, making them slippery, and hydrocarbons degrade roofing sealing systems. Heat and dust also damage electrical and electronic components, sometimes leading to unpredictable failures that reduce productivity.

 

Certain gases and fine dust particles also have explosive properties to varying degrees (Kst, Pmax, EMI, gas classification). Under certain conditions (LEL, UEL, confined spaces), explosive atmospheres (ATEX) can form, causing human and material damage—including eardrum rupture, severe injuries to ears and lungs, and flying debris—which can be fatal.

 

WATTOHM operates at multiple levels on industrial sites. We implement ventilation systems designed to keep concentrations well below the LEL, helping to reclassify ATEX zones (e.g. centralised cleaning, ventilation integrated into processes).

WATTOHM designs and installs ATEX-compliant systems in accordance with Directive 2014/34/EU, serving two main purposes: workplace aeration and purification to mitigate ATEX risks by influencing one of the six explosion criteria; and certified safety solutions to minimise impact on people and the environment where necessary.

Optimising our global solutions while minimising their environmental impact is our commitment. WATTOHM works on process improvement with the ultimate goal of optimising energy consumption in industrial installations.

Adjusting equipment usage time to the actual needs of workshops generates significant energy savings, ensuring operator safety within its ecosystem as part of an eco-responsible approach.

Ventilation systems consume energy due to the air flow rates involved and the pressure losses generated by networks and specific obstacles (filters, batteries, extraction devices).

 

WATTOHM optimises energy consumption by reducing air flow as much as possible, minimising aerodynamic resistance in networks, selecting low-pressure-drop filters, and using variable-flow fans tailored to actual needs. We also implement systems that recover the energy contained in polluted air extracted from processes to preheat compensation air in buildings. Additionally, we collaborate with ADEME to offer Energy Saving Certificates (CEE) to help clients reduce their environmental impact.

Certain industries also generate large quantities of production waste, such as paper, empty bags, cardboard, aluminium, and metal shavings. The continuous and automated suction and pneumatic transfer of these waste materials to disposal bins support the 5S methodology in production workstations, saving operational time compared to manual handling.

 

WATTOHM provides eco-friendly solutions to meet these specific demands across all industrial sectors.

Just like workplace exposure concentrations, atmospheric emissions are regulated and regularly monitored by DREAL in France, as well as by private organisations and control agencies internationally.

 

For example, the ministerial decree of 2 February 1988 sets a concentration limit of 40 mg/m³ for dust; the allowable concentration for fluorine-based elements is 5 mg/m³; the asbestos concentration limit is 1 mg/m³; and the mercury emission limit in steelmaking is 0.5 mg/m³ (see full texts on aida.ineris.fr).

 

WATTOHM designs and implements installations in compliance with current regulations, according to the type of pollutant and the site classification. This compliance is verified by an authorised organisation during the commissioning phase of the installation.

Why choose us for your projects?

The design of an industrial ventilation system is a complex and multidisciplinary process involving numerous technical, economic, energy-related, ergonomic, and human factors.

 

Thanks to WATTOHM’s expertise and experience, we offer audits on existing installations, including upgrades, capacity increases, ATEX compliance, energy optimisation, and noise level improvements.

Design, Implementation, and Installation Monitoring

To design our installations, we use digital tools such as AutoCAD for 2D designs, SolidWorks 3D, and the FlowSimul numerical simulation tool to validate extraction speeds at workstations in compliance with INRS and CARSAT recommendations, calculate pressure losses, or simulate airflow and thermal convection within a building.

 

Client relations are essential to the success of a project, which is why personalised support is one of our key commitments. A dedicated and exclusive project manager will assist and guide you through every stage of your project.

Maintenance & Training

We offer multiple service levels for our projects, ranging from performance monitoring to a full installation audit.

Ventilation and air purification systems are considered Collective Protection Equipment under the Labour Code (Article L4121-1). As such, an annual or biennial inspection is mandatory for installations that recycle filtered air.

WATTOHM offers this monitoring service and takes a proactive approach by continuously improving these installations, focusing on energy consumption, ATEX compliance, and reducing consumable usage.

Our systematic preventive maintenance contracts include regular interventions on installations to monitor performance and carry out first-level maintenance on key components, such as filter media, solenoid valves, sensor and electronic probe checks, gear motor oil changes, and lubrication.

Ventilation, dust removal, and pneumatic waste transport systems are autonomous installations designed to operate at a single workstation or in a 3×8-hour shift pattern plus weekends. Their monitoring can be ensured continuously through strategically placed and selected electronic sensors within the installation. These sensors enable real-time control of essential parameters and, through multiple alert levels, allow timely interventions.

Because traditional education does not specifically teach our professions.

We understand that experience, empirical knowledge, and collaborative sharing are essential to gaining the key skills required to set up, operate, and maintain an industrial installation sustainably. WATTOHM offers several types of training programmes:

 

  • Training in the operation and maintenance of installations
  • Training in general aerodynamics techniques

These training sessions take place either at our offices in Charnay-lès-Mâcon (71) or on-site at our industrial clients’ locations, including practical sessions on existing installations.

 

Several topics are offered by WATTOHM, based on our field experience and feedback from our user clients, and additional themes can be provided upon request.
