Quality in Every Step: How Schleifenbauer Builds on Precision and Trust

In the world of data centres, reliability is everything. Power must never fail. Monitoring must always be accurate. And systems must work together flawlessly. That’s why Schleifenbauer builds its products to the highest quality standards – not just during final checks, but in every part of the process.

Whether it concerns PDUs, Inline Meters or our EnerTree DCEM software, quality is embedded in the design, production, testing and service. Every solution is produced in-house by Schleifenbauer under the principle of zero compromise on quality.

A Standard of Quality: ISO 9001 Certified

Schleifenbauer operates under a certified ISO 9001 quality management system, which ensures:

• Full traceability of components and end products
• Standardised workflows and assembly instructions
• Continuous quality control and documentation
• Ongoing improvement and customer satisfaction as a guiding principle

Every PDU and Inline Meter receives a unique serial number linked to a complete test report. These test results are instantly retrievable worldwide, so we can always verify performance and compliance.

Component Control Starts at Goods Receipt

Half of quality is achieved in preparation. That’s why:

• All incoming components are checked for specifications, dimensions and functionality
• We prefer to work with local, long-term suppliers whom we actively support
• Most components arrive packaging-free in reusable Schleifenbauer crates

Any component that fails inspection is rejected immediately. Only perfect parts move on to assembly.

Assembly: Precision in Practice

At Schleifenbauer, everything is built in-house. From aluminium PDU housings to the wiring of sensors, relays and connectors:

• Each employee works according to clear instructions
• Every cable is cut to length with precision and installed CE-compliant
• ESD-safe workstations and high-grade tools are used throughout

Quality is visible in every detail – from laser engravings to clean internal layouts.

Testing: Zero Faults is the Standard

Each unit – PDU or Inline Meter – undergoes individual testing, including:

• Power distribution per phase and outlet
• Measurement accuracy, sensor response and protocol functionality (SNMP, Modbus, REST API)
• Relay switching behaviour and electrical safety

All results are digitally recorded and linked to the serial number. These reports are retrievable in seconds, anywhere in the world.

The result? A claim rate of just 0.02%. But our goal is higher: zero defects.

“Quality isn’t a final check – it’s a mindset. Every day, for every product.” – Renze Elings, Operations Support Engineer

Software Quality: EnerTree DCEM

The same high standard applies to our software. EnerTree is developed with modern architecture and focuses on:

• Stability, security (TLS 1.3, audit logs, secure boot), and scalability
• Real-time data analysis from up to 10,000 PDUs
• Tight integration with existing DCIM and IT systems
• Automatic updates, fault detection, and intelligent alerts

EnerTree is also completely licence-free, ready to use without training or consultancy. Plug-and-play, but enterprise-grade.

Sustainability as Part of Quality

At Schleifenbauer, sustainability is part of quality. We minimise waste, recycle all remaining materials, and deliver packaging-free directly to the data centre’s white space. Even transport is done by partners using electric vehicles.

In Summary

At Schleifenbauer, we build with precision – not because we have to, but because we understand what’s at stake in data centres. Quality is not just a final check, it’s a conscious decision – made every day, in everything we design, build and deliver.
