That was the situation facing AT‑Härtetechnik, a Munich-based heat treatment specialist serving a wide range of industrial sectors.

With the end-of-life of their existing digital infrastructure, AT-Härtetechnik made the decision to transition to a more modern, scalable platform—one designed not just to replace what they had, but to enable deeper operational insight and long-term digital growth.

**From Legacy Constraints to a Modern Digital Foundation**

AT-Härtetechnik had been operating with the PT9800 system for years. While reliable in its time, the platform had reached its technological limits. Reporting flexibility, performance tracking, and advanced production analytics were increasingly difficult to achieve.

Rather than extending the life of a system approaching obsolescence, the team chose to move forward with a future-ready solution that could support both current operations and evolving digital objectives.

The decision to deploy QMULUS was driven by two key factors:

- The **end of life of PT9800**, requiring a clear and stable replacement
- The **expanded feature set of QMULUS**, particularly in performance monitoring, process optimization, and production statistics

**Scope of the Deployment**

The QMULUS installation was carried out at AT-Härtetechnik’s Munich facility and includes:

- **15 connected assets (furnaces and related equipment)**
- **One production site**
- **A 5-year multi-year contract**, reflecting long-term commitment and confidence in the platform
- **Non-industry-specific production**, supporting a diverse customer base across multiple sectors

This deployment marked a direct transition from a legacy system to a modern, data-driven operational platform.

**Addressing Real Operational Priorities**

AT-Härtetechnik’s objectives were clear and pragmatic. The focus was not on digitalization for its own sake, but on solving tangible operational challenges:

- **Performance tracking** across connected assets
- **Process optimization** based on real production data
- **Production statistics** to support better decision-making and reporting

By consolidating operational data into a single environment, QMULUS enables visibility that was difficult—or impossible—to achieve with the previous system.

**Early Feedback from the Shop Floor**

While it is still early to quantify long-term efficiency or cost improvements, early feedback from AT-Härtetechnik has been notably positive.

The platform is being used extensively, and the team has reported high satisfaction with how QMULUS performs in day-to-day operations. This level of adoption is a strong early indicator of value, particularly in industrial environments where usability and reliability are critical to success.

**Building for the Long Term**

For AT-Härtetechnik, the move to QMULUS represents more than a system replacement. It is a foundational step toward sustained digital operations—one that supports continuous improvement, data-driven insights, and future scalability.

As more industrial companies face the retirement of legacy platforms, AT-Härtetechnik’s approach illustrates a clear path forward: replace aging systems with a modern, connected solution that delivers immediate operational value while laying the groundwork for what comes next.
