The staged combustion nozzles generate 25% FGR which creates multiple flame zones reducing peak temperatures. For a German hospital’s boiler, upgrading to these low NOx parts cut emissions by 60% achieving compliance with EN 303-5. Parts are also back-compatible with most leading burner manufacturers, providing an affordable solution to environmental compliance.

Frequently Asked Questions

Can Stiefel design and manufacture boiler parts for specific models that are not usual?

Yes. Our range of OEM/ODM services covers design and manufacturing by CNC machining, laser welding, and rapid prototyping tailored to custom specifications. For instance, we worked with one European gas boiler manufacturer to implement IoT sensors into control panels, which saved them 30% of their internal product development time. Modified non-standard flange designs, custom seals for cryogenic applications, and other specialized orders are precisely engineered within 6–8 weeks by our dedicated engineering teams.

Advanced Material Engineering Accomplishments

Advanced Material Engineering Accomplishments

Stiefel demonstrates how silicon carbide ignition transformers (which can withstand temperatures of 1,400°C) and PEEK-sealed valves (which do not react with aggressive fuel chemicals) assist in chemically extending the lifespan of materials. Maintenance interval extensions, along with extended part lifespan, were also noted at a customer’s refinery in Mexico which experienced a 45% reduction in annual replacement costs.
International Certification and Compliance

International Certification and Compliance

Our piston boiler parts are certified to CE, ATEX, UL, and CSA standards guaranteeing utilization in regulated markets globally. Take for instance, our explosion proof solenoid valves (EEx d IIC T6) certified for Zone 1 hazardous areas that allow installation in LPG turbines operating in the boilers both in Europe and North America.
Predictive Maintenance Supported by Data

Predictive Maintenance Supported by Data

Thanks to our internet capable appliances (e.g. sensors located at the actuators and valves), clients are provided with continuous reports on the condition of components. A client operating a dairy product manufacturing plant based in The Netherlands was able to analyze data to foresee nozzle replacement on a scheduled basis, which helped reduce unplanned outages by 35% while optimizing their maintenance spending.
