Coil Innovation & Merlin^®

Holistic humidification and air conditioning for demanding production and testing processes

Coil Innovation GmbH, based in Eferding (Upper Austria), is an internationally active company in the energy technology sector, specializing in the development and production of high-quality, environmentally friendly air-core reactors and customized coil solutions.

The company supplies customers worldwide and plays a key role in ensuring the stability of modern power grids with its energy-efficient products. Reactors limit short-term high currents, protect connected systems like a “shock absorber”, and support the safe and efficient integration of renewable energy sources while increasing efficiency.

Initial Situation

For safety- and quality-relevant production processes as well as sensitive testing procedures, stable climatic conditions are essential.

Different areas such as production facilities, office spaces, and especially the high-voltage testing laboratory place specific demands on humidity levels and air conditioning. The goal was to implement a holistic and flexibly controllable solution that supports production conditions and enables precise testing processes under consistent environmental conditions.

Solution

To meet these requirements, a combined solution of direct room air humidification and integrated humidification in air handling units was implemented.

For production and office areas, ALPHA high-pressure direct atomization is used in the room. Fine high-pressure atomization is achieved via nozzle lines (AER pipes) in production zones and AER office modules in office and break areas. An integrated water treatment system ensures hygienic and technical reliability.

In central ventilation and air conditioning systems, ORBIT WING^® and CORBIT^® high-pressure AHU humidification systems are installed. These are directly integrated into the systems and ensure uniform and hygienic air conditioning through precise humidification and efficient droplet separation—especially in sensitive testing areas such as the high-voltage laboratory.

Implementation

The implementation was carried out step by step and modularly, adapted to Coil Innovation’s operational processes.

Existing zones were expanded and additional applications were added. Thanks to the scalable system architecture, both room and AHU humidification solutions could be flexibly integrated without significantly disrupting ongoing operations.

Result

Today, Coil Innovation benefits from stable climatic conditions in all relevant areas.

The systems support reliable production processes as well as precise air conditioning in the high-voltage testing laboratory, ensuring consistent conditions for demanding testing procedures. At the same time, a comfortable indoor climate is created in office and working areas.

Overall, the implemented solutions sustainably contribute to process reliability, quality, and workplace comfort.

Customer Statement

“The combination of direct room atomization and integrated AHU humidification provides exactly the flexibility we need for our diverse areas. We particularly appreciate the modular expandability and reliable operation during ongoing processes.”
