Advantages of Stiefel's Boiler Parts

Comprehensive Compatibility for Major Boiler Brands

We sell a variety of boiler parts, all of which are compatible with leading brands like Riello, Honeywell, and Baltur. Our silicon carbide core ignition transformers outperform legacy industrial boiler components with 35kV sparks at 1,200°C. A U.S. paper mill uses OEM-quality flame sensors and fuel filters that were designed for their Riello burners and converted to fit easily into the existing infrastructure. Our parts condensing commercial boilers and heavy duty industrial systems come with comprehensive cross-reference guides for easy identification and installation.

The safety importance of these valves is critical whereby high-torque solenoid coils paired with lightweight armatures achieve rapid actuation. In the LPG storage area of a chemical plant, our valves achieved a 20ms shut-off time satisfying OSHA emergency responsiveness, while the ATEX-certified enclosures ensured safety in Class I, Division 1 areas. The ATEX-certified enclosures also ensures safe operation in class one 1 zones. The primary + secondary redundant coil configuration guarantees reliable function under extreme vibration, protecting sunlight fail-safe operation.

Frequently Asked Questions

In what ways does Stifel protect and enhance the lifespans of boiler parts with respect to high temperatures?

On our part, we apply Inconel, tungsten carbide, and ceramic coatings to these structures. At a powerplant in the U.K, we've had success with spiral fin heat exchangers. They not only possess ceramic coatings but also resist sulfuric acid corrosion found in high sulfur gas boilers. We've maintained 92 percentage thermal efficiency over a decade. Precession platinum rhodium tip ignition electrodes sustain over ten thousand cycles at a staggering 1,400 degrees centigrade. These outperform stainless steel electrode alternatives deemed ‘standard’ by thrice for industrial furnaces.

Dependable Parts for Our Outdated Boiler System

Stiefel’s boiler parts have been a lifesaver for our 20-year-old industrial boilers. The replacement ignition transformers and flame sensors work without a hitch, and the renewed compliance with our obsolete Honeywell controls was flawless. Since switching to Stiefel, we’ve observed a 70 percent reduction in unexpected system shutdowns alongside increased operational efficiency thanks to the quick order fulfillment policy for urgent parts such as fuel filters that are critical to maintaining smooth, uninterrupted processes.
