Case Study: Keller Lufttechnik achieves transparent cross-departmental project management with PSI Software’s PSIpenta ERP

Keller Lufttechnik - Customer Case Study

Keller Lufttechnik, a manufacturer of industrial extraction systems, faced a lack of process transparency due to numerous in-house solutions that failed to provide an overall view of its project-based value creation. This led to media discontinuity and a lack of control over deadlines and budgets. To address this during a planned ERP upgrade, the company partnered with vendor PSI Software to implement a more integrated system.

PSI Software implemented its PSIpenta/Project Structures module, which introduced consistent, cross-departmental project management with milestone planning and time tracking. The solution provided Keller Lufttechnik with a unified view of all projects, enabling them to identify optimization potential, control critical paths, and perform more transparent, project-specific costing. This shift strengthened customer confidence and established a new foundation for efficient, company-wide processes.
