The gradual development of industrial sites requires not only scaling, but a strategic approach for technical systems, which maintain the production environment. That’s why when finalizing the third stage of the WITTE Automotive project in Ruse, Bulgaria, with modifying the entire production complex, indoor climate management is considered an especially important element of long-term infrastructure. The new production and logistical space put higher requirements on energy efficiency, flexibility of the installation and guaranteed stable microclimate during fluctuating loads. It was within this stage of project that Hoval implemented a decentralized solution for indoor climate control, fully customized to the specific areas in the company.

The system is designed to ensure a stable and predictable environment, consistent temperature, high quality of air and reliable microclimate. "The applied decentralized approach allows air conditioning to be carried out directly in individual sections, without building an extensive centralized air duct network," Hoval informed BalkanEngineer.com.
The company also added, "Hoval TopVent SP-9 heat pump units have been implemented in the production premises, which integrate heating, cooling and ventilation capabilities into one device. The system supplies the treated air directly to the work areas, which allows for maintaining an even temperature distribution and precise control over the indoor climate."
The control of the system is accomplished through TopTronic C by Hoval, which allows for precise regulation of work parameters regarding specific conditions in different production facilities. This ensures reliable control and installation performance during fluctuating load modes, common for industrial environments. Additionally, the solution provides real-time monitoring, which enables continuous monitoring of equipment performance, faster response to deviations, and more efficient maintenance.
