Embedded automated QA supporting Danfoss Drives worldwide

Reliable, automated QA for mission-critical frequency drives

Danfoss frequency drives operate in mission-critical environments, powering applications ranging from HVAC systems and industrial machinery to marine vessels and energy infrastructure. Reliability, safety, and repeatability are fundamental requirements for every product release.

Danfoss maintains a continuously evolving portfolio of frequency drives, firmware versions, and hardware variants. Quality assurance is therefore not a one-time activity, but a permanent operational function that must deliver consistent results across generations, configurations, and global development and production environments.

The challenge is sustaining reliable, automated validation as product complexity, scale, and release cadence increase over time – without disrupting development, production, or global collaboration.

Ongoing automated test delivery for Danfoss Drives

Since 2008, Proekspert has operated as a long-term QA partner for Danfoss Drives. We run and continuously evolve automated testing environments and workflows as an embedded part of Danfoss’s product development and validation ecosystem.

Our role is not limited to test execution. We take responsibility for maintaining and improving the automated QA infrastructure in line with Danfoss’s technical strategy, tooling choices, and product roadmap.

Key responsibilities and deliverables:

• Continuous development and maintenance of automated regression, functional, and hardware-in-the-loop test cases across drive variants
• Operation and upkeep of test lab infrastructure and automation assets
• Modernization and stabilization of legacy test systems based on LabVIEW and NI TestStand
• Improvements to test data handling, reporting, and transparency to support efficient analysis
• Incremental refinement of operator user interfaces to support daily test operation
• Rapid adaptation of test coverage as new drive models, firmware versions, and features are introduced
• Close cooperation with Danfoss development and QA teams across Denmark, Finland, China, and India

Over time, this work has ensured that Danfoss’s automated QA environment remains reliable, maintainable, and aligned with evolving product and organizational needs.

Bottom line: With more than 15 years of continuous cooperation, Proekspert supports Danfoss Drives by operating and evolving a robust automated QA capability that helps sustain product reliability, manage validation risk, and support ongoing product development at scale.

Continuous improvement of QA operations

Through long-term collaboration, Danfoss’s automated QA operations have been steadily refined and expanded. Automated testing today supports all major drive variants and firmware generations, reducing manual effort where it still exists and improving consistency across test environments.

Engineers and operators benefit from clearer test procedures, improved user interfaces, and more transparent access to test results and data. Faster feedback supports troubleshooting and analysis, while unified approaches across labs make it easier to roll out updates and improvements globally.

Every improvement is shaped by real operational experience and lessons learned over years of cooperation, helping keep Danfoss’s QA environment resilient, adaptable, and future-ready.

Impact for the client’s organization

These technical solutions and continuous improvements aren’t just engineering wins – they deliver measurable business impact for Danfoss. Here’s how our long-term partnership is driving real results:

• Reduced validation risk. Stable, supported test platforms improve confidence in test results and help manage quality risks across frequent releases and product changes.
• More efficient engineering workflows. Automated and repeatable testing reduces manual effort and supports faster, more consistent decision-making across development and QA teams.
• Global consistency at scale. Shared test environments, procedures, and automation assets enable consistent validation practices across Danfoss sites worldwide, supporting smooth collaboration and rollout of new products.
