Benefit of Stiefel’s Boiler Parts

Budget-Friendly Maintenance with Global Logistics Support

We design our boiler parts so that they incur the least operational expense in the long run. A butterfly valve from one of our Spanish clients’ ceramic factories was far easier to maintain due to the modular design our engineers developed. Now, replacement of the ceramic coated discs takes half the time since the valve doesn’t need to be taken off the pipeline. Ignition electrodes and pressure regulators with technical support provided 24 hours a day, seven days a week, lead of no delay for bulk items like ship valves with same day dispatch links across the globe. A Canadian client district heating plant using our service kits which come with ready to use spare parts that have CE, UL and CSA markings on the components, saved 25% on stock costs.

The regenerative heat exchangers save 85% of exhaust gas heat from combustion and simultaneously preheat the combustion air. In addition, the VSDs reduce energy spent on the blower by 30%. With the installation of our heat exchangers and VSDs, a Dutch dairy’s pasteurization system saw natural gas consumption decline by 28% and recovered the costs over 12 months. These components are perfect for upgrading older burners because they improve energy savings and lower operational expenses.

Frequently Asked Questions

Are Stiefel's boiler parts compatible with both gas and oil boilers?

Our parts are fuel adaptable which provides structure versatility for various fuel options. On the gas side we have premix nozzles and FGR valves with ultra-Low NOx emissions (≤30 mg/Nm³) while oil boilers have high pressure pumps (200 bar) and atomization viscosity controllers for heavy fuel optimization. Our Russian maritime boiler customer using dual fuel systems with our parts was able to cut fuel usage 18% just by switching between gas and bio-diesel showing our systems are adaptable fuel diverse systems.

Advanced Material Engineering Accomplishments

Advanced Material Engineering Accomplishments

The work done by Stiefel to seamlessly prolong materials lifespans can be seen in silicon carbide ignition transformers (1,400°C resistive) and PEEK-sealed valves (chemically inert to aggressive fuels). As noted by one of our customers in a Mexican refinery, these materials extend maintenance and part lifespans which helped reduce their annual replacement costs by 45%.
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.
