RielloPro Technical Services

Comprehensive support from commissioning through the entire operational lifecycle of your heating system

01

Commissioning & Start-Up

Factory-trained technicians handle initial burner commissioning, combustion tuning, and safety interlock verification. We calibrate air-fuel ratios, measure flue gas composition (O2, CO, NOx), and document all parameters in a certified commissioning report compliant with EN 676 / EN 267 standards.

02

Preventive Maintenance Programs

Scheduled inspection programs covering burner head cleaning, nozzle replacement, electrode gap adjustment, flame scanner calibration, and fuel pump pressure testing. Maintenance intervals are tailored to operating hours, fuel type, and environmental conditions to maximize uptime.

03

Emergency Repair & 24/7 Support

Rapid-response breakdown service with target response times under 4 hours for critical installations. Our hotline connects you directly to combustion specialists who can diagnose common fault codes remotely before dispatching a field engineer.

04

Spare Parts Supply

Genuine OEM spare parts stocked in regional warehouses for next-day delivery in most markets. Common wear items include nozzles, electrodes, photocells, blast tubes, air damper servos, and control boxes. Obsolescence management ensures availability for legacy models.

05

Combustion Efficiency Audits

On-site combustion analysis using calibrated flue gas analyzers to measure real-time efficiency, excess air percentage, and emission levels. Audit reports include actionable recommendations for tuning adjustments, component upgrades, or burner replacement to optimize fuel consumption.

06

Retrofit & Upgrade Services

Burner replacement programs for upgrading legacy installations to modern low-NOx, high-efficiency units. We handle the engineering survey, burner sizing calculation, mechanical adaptation, electrical wiring, and re-commissioning as a turnkey project.

07

Technical Training

Hands-on training programs for maintenance staff covering burner operation, troubleshooting fault codes, seasonal shutdown/start-up procedures, and safe combustion practices. Training is available at our facility or on-site at your location.

Service Coverage & Response Times

Our service network covers 85 countries through a combination of factory-direct engineers (Western Europe, Middle East, Southeast Asia) and authorized service partners (remaining territories). Current average response times as of Q4 2025:

Region Emergency Response Scheduled Visit Spare Parts Delivery
Western Europe < 4 hours 2-3 business days Next-day
Middle East & Africa 8-24 hours 5-7 business days 3-5 business days
Asia-Pacific 12-48 hours 5-10 business days 5-7 business days
Americas 24-48 hours 5-10 business days 3-7 business days

Limitations: Emergency response times are targets, not guarantees, and depend on technician availability and geographic accessibility. Installations in remote locations (offshore platforms, mining sites, island territories) may require extended lead times. Service for legacy models discontinued before 2005 is limited to spare parts supply only — on-site commissioning for these units is no longer offered.
