Lemoine France S.A.S. & Merlin^®

Stable production conditions in paper processing at Lemoine

Founded in 1978 in France, Groupe Lemoine is an international manufacturer of cotton-based hygiene and personal care products (cotton swabs). The company has grown from a family-owned business into the European market leader and the world's second-largest supplier in this segment, serving more than 300 customers across multiple production sites on five continents.

Initial Situation

In the mechanical paper-processing workshop, production performance fluctuations occurred, particularly during changing weather conditions such as dry periods and thunderstorms. Variations in air humidity negatively affected process stability and created quality risks during production.

Solution

To stabilize climatic conditions, Lemoine chose a merlin^® high-pressure humidification system. The ALPHA system was installed together with two AER 9v atomization modules, enabling precise and reliable air humidity control within the production area.
The solution features a modular design and can easily be expanded with additional zones if future requirements increase. Currently, one zone is in operation.

Implementation

The objective was to maintain a constant relative humidity level of 55%. The production area covers approximately 900 m² with a volume of 5,400 m³. Installation was completed efficiently, with only one month between order placement and commissioning. In addition, technical consultation made it possible to avoid the installation of an extra water treatment unit because a suitable system was already available on site.

Result

Since commissioning, no general deterioration of the production process has been observed during weather changes, unlike the situation before installation. Production conditions have become significantly more stable. However, it is still too early to validate the results with concrete performance data.

Customer Statement

"The installation was completed very quickly. We especially appreciated the technical consultation, which enabled us to avoid installing an additional water treatment unit."

Conclusion

With the introduction of the merlin^® ALPHA high-pressure humidification system in combination with the AER 9v atomization modules, Lemoine has successfully stabilized climatic conditions in its paper-processing operations. The project stands out due to its rapid implementation, efficient system design, and modular flexibility, providing a solid foundation for consistent product quality and future expansion.
