Reference Project: hvac/r & heating

Integrated Integrity for Boiler Pressure Vessels.

Nolek partnered with NIBE in Sweden to develop a versatile Leak and Proof Tester designed for high-capacity production. This system validates 31 different types of boiler pressure vessels, utilizing automated robotic loading to ensure seamless throughput and consistent quality validation at pressures up to 15 bar.

◈  The Challenge

Validating a wide range of vessel geometries (31 variants) with high reliability while integrating into a robot-driven automated production line.

◈ The Solution

A high-precision workstation featuring exchangeable fixtures and HMI-adjustable proof testing to accommodate rapid model changes.

Advanced Automation Standards

High-pressure Helium validation designed for 24/7 automated boiler production.

Robotic Handling

  • Fully robot loaded operation
  • Automated fixture clamping
  • Consistent production cadence
  • Reduced manual intervention

System Versatility

  • Validated for 31 model types
  • Exchangeable fixture system
  • Rapid tool-less changeover
  • HMI-based model selection

Dual Pressure Test

  • Up to 15 bar Proof Test
  • 2 bar Helium tracer leak test
  • Sensitivity to 10-3 mbar·l/s
  • Safety interlocked HMI controls
