Regulatory compliance and industrial boiler inspection

As a certified service provider, AS SCAN is authorized to carry out industrial boiler inspection and mandatory safety evaluations. We provide all necessary documentation for boilers operating above 110°C and industrial steam boilers, ensuring full compliance with national regulations. This includes semi-annual safety inspections and verification of pressure-related components.

With our services, you minimize administrative overhead and ensure safe boiler operation through accurate and timely compliance.

Our certified technicians perform thorough service on all key boiler systems.

Scheduled maintenance and preventive electrode boiler service

We manage all service intervals to ensure electrode boiler maintenance is performed on time. Regular maintenance not only extends your system’s life, but also reduces energy waste and prevents unplanned downtime. As part of our preventive maintenance, we proactively replace critical components, optimizing reliability and performance.

Precise tuning of control systems helps reduce energy consumption and improve performance.

How often should high voltage boilers be serviced?

To ensure long-term safety, efficiency, and compliance, we recommend the following service intervals on hotwater- and steamboilers:

• Annual servicing for cleaning and mechanical checks
• Biannual safety inspections for systems operating above 110°C
• Four- and eight-year intervals for in-depth internal inspections and pressure testing

These intervals form the foundation of our service programs—and are carefully designed to keep your boiler in top condition while minimizing downtime and risk.

Our boiler inspection procedure includes:

• Full visual and mechanical inspection
• Safety system testing
• Documentation for compliance
• Internal reviews and pressure testing (as required)

Service intervals and procedures with AS SCAN

Regular servicing of electrode boilers is essential for operational reliability, efficiency, and long service life. At AS SCAN, we follow fixed service intervals with clear inspection procedures to ensure the boiler operates optimally and meets all safety requirements. Below is an overview of the tasks included in the annual, 4-year, and 8-year inspections.

Annual Service

Every year, we carry out a detailed mechanical inspection and industrial boiler cleaning to ensure optimal performance and safety:

• Visual inspection of electrodes, insulators and internal components
• Cleaning of boiler shell to remove scale, deposits and sludge
• Leak check of circulation pump and actuator shaft seals
• Inspection and replacement of electrode tips (every two years)
• Cleaning and testing of water level glass and pressure tubes
• Inspection of high-voltage porcelain bushings for cracks or damage
• Safety system testing according to AS SCAN protocols
• Nitrogen pressurization and system restart verification

Every 4 Years

In addition to the full annual service, we:

• Replace all high-voltage porcelain insulators
• Conduct internal inspection by third party for cracks or unacceptable corrosion

Every 8 Years

Along with the 4-year service tasks, we also perform:

• Pressure testing of the boiler system (1.3x safety valve pressure)
• Visual inspection during pressure hold to detect any leakage or defects

Every inspection is performed by certified AS SCAN technicians using standardized protocols.

Performance optimization for electrode boilers

We optimize your boiler’s settings based on data analysis and operational feedback. Whether your priority is production stability or energy efficiency, our tuning process reduces energy consumption and operating costs. Optimization is essential for electric boiler systems, especially when integrated into modern production or when you ned to use the power regulation environments.
