Planning factors for plants for pollutant capture

A plant for pollutant capture in the industrial environment is to be designed according to requirements. That's why it's important to pinpoint needs. You will find out which planning factors have to be considered in the following interview with our expert Sascha Mohe, Product Manager for the air technology sector at DENIOS.

Mr. Mohe, you are responsible for the Air Technology Systems division at DENIOS AG. Among other things, they offer work desks and free standing workplaces. What needs do these products cover?

Those who work with hazardous substances are exposed to an increased health risk. The Occupational Health and Safety Act stipulates that dangers always have to be eliminated or mitigated directly at the source. Our work tables are therefore used both in industrial workplaces, where the employee is to be protected against harmful emissions during his work. But also in activities in the pharmaceutical environment, such as the transfer of powdered CMR substances.

STOP! Did you know?

When selecting occupational safety measures in the context of the risk assessment, the so-called STOP principle applies:

S Substitution

T Technical Measures

O Organisational Measures

P Personal Measures

The sequence of measures is synonymous with their prioritization. A technical solution, such as a pollutant workplace is preferable to personal measures such as the use of PPE.

The protection of the employees is therefore decisive in your product area. What is important when choosing a suitable system?

First of all, a detailed needs analysis is required: Which materials are being worked on? What is the actual protection goal? Is it about protecting the product from cross-contamination or protecting the employee working with highly active substances? A clear, shared picture of the requirements that must be met needs to be determined.

They describe that you advise each customer individually. Is the solution also customer specific? Do you offer the appropriate flexibility as a manufacturer?

That is indeed the case. Air conditioning systems are managed by DENIOS under the brand name "Vario-Flow". So that we can express that we can adapt to the respective customer process with different air techniques. Vario-Flow also means flexibility, as well as robust industrial requirements and high-purity GMP workspaces.

To what extent does the protective measure interfere with the employee's activity?

The customer's process is the focus. We want to have as little influence as possible on the customer's process and use our solution more supportively. Therefore, we look at exactly how and with what work is done. For example, the largest possible engagement surface is important for a particular process, while in another it does not play a significant role.

What must be considered when designing a work table or a free workplace?

How much space is required for the actual process and whether media connections such as sockets and water are required, are the two main criteria for designing a workplace. In the case of a permanent workplace, issues such as ergonomics, position of fixtures, lighting and noise level must always be taken into account. In addition, it is important for the customer to know that we work partly with considerable amounts of air. What do we do with the extracted air? It is possible to filter and clean them, or to bring the exhaust air and the most efficient place into the open - and if so, where and how is this realized? The issue of energy efficiency is certainly relevant here as well.

Are there legal regulations that have to be observed?

In principle, the customer as an employer is obliged to carry out a corresponding risk assessment for workplaces where employees handle hazardous substances. On this basis, the configuration of the workbench or free workstation can be based. Therefore, I always recommend bringing as many internal and external stakeholders as possible together. Authorities and professional associations have different ideas in some cases than the internal occupational safety experts.


Does the subject of explosion protection have a special relevance?

The crucial question at the time of the explosion is: can it be a system? Customers argue here quite differently and also apply different valuation principles, for example when considering the amount of hazardous substance used. For example, in laboratories explosion protection is often not an issue due to the quantities of hazardous substances used. In principle, we can equip all our systems accordingly with explosion protection. 

They also offer a wide range of services. How does the customer find his way here?

In fact, the plants are usually based on a composition of modular components. So it is rare for us to sell one product in the same design to two different companies. Therefore, we consider the close cooperation with the customer from the beginning and the advice to be extremely important in order to satisfy the customer in the best possible way. For laboratory applications we also offer standardized systems.

In times of Industry 4.0 - how networked are the solutions at DENIOS?

Monitoring instruments such as actual exhaust air or supply air monitoring, differential pressure measurement with filters or fault messages have been used very frequently for many years. In recent years, increased requirements for the monitoring of error messages, user behavior, maintenance, etc. have been added. DENIOS has developed a cloud-based solution (DENIOS connect) to assist customers in the proper and efficient operation of technical room systems and containment solutions. DENIOS connect bundles testing, maintenance and documentation requirements in an easy-to-use application. The recommended annual maintenance is displayed on the product and can now be conveniently ordered directly via the application. So we offer the customer a holistic solution concept.
