Stiefel's Boiler Parts Benefits.

Complete Compatibility With Major Boiler Brands

We particularly specialize in the manufacture of parts for boilers, with 98% compatibility to the top brands like Riello, Honeywell, and Baltur. Our silicon carbide core ignition transformers which replace legacy components in industrial boilers, emit 35kV sparks at 1,200°C. A U.S. paper mill saw a 30% reduction in repair costs after using our OEM-quality flame sensors and fuel filters that were designed for easy integration into existing Riello burners. No matter if you are looking for parts for commercial condensing boilers or heavy duty industrial systems, our cross-reference guide will help you quickly identify and install the parts.

Stiefel’s gas solenoid valves integrate security and efficiency to meet the challenges posed by boiler systems. The bodieswhich directly endure the heating zone are made of 316 stainless steel while the diaphragms are PTFE sealed. These valves endure thermal shock 300°c, chemical attack as well as corrosive chemicals, qualifying them for industrial boilers in chemical plants and power stations. The double coil design gives redundant operation. In hospitals or steam dependent food processing facilities, production, the primary coil fails wherein continuous control is critical, secondary coil activation occurs after 50ms. With our valves, a district heating boiler in germany achieved 95% reduction in gas leaks compared to previous models due to the metal- to-metal seat design and automated leak testing performed with 100% helium mas spectrometry.We expand the capabilities of primary boiler control systems with access through 4-20 mA signals that provide real time monitoring concerning the valve position and provide diagnostics.

Frequently Asked Questions

Does Stiefel offer a service for specific models of boilers to manufacture individual parts?

Definitely. Our services include custom part development through CAD/CAM, and include custom CNC machining, laser welding, and rapid prototyping. For instance, we collaborated with the European boiler manufacturer to design a control module featuring integrated IoT sensors that considerably streamlined the product development time by 30%. No matter what your requirements are, be it modified non-standard boiler flanges or proprietary seals designed specifically for cryogenic applications, our engineers will work together to ensure that you get tailor-made solutions within six to eight weeks.

Dependable Parts for Outdated Boiler Systems

Stiefel’s boiler parts have really saved us a lot of stress with our 20 year old industrial boilers. The replacement ignition transformers and flame sensors are working perfectly and they even work with our old Honeywell controls. We are reducing unexpected shutdowns by more than 70% since switching and also thanks to same day servicing for urgent fuel filter parts.

Tailored Stiefel Solutions for Our Waste Boiler Project

Stiefel provided us with exceptional tungsten carbide nozzles along with valves that are resistant to corrosion. The abrasively charged particles and high temperatures of over two years have not replaced their parts. With Stiefel, satisfying tight deadlines was simple due to their speedy prototyping and material selection.

Stiefel as an International Industry Leader: Cost-Effective Maintenance

As a commercial property manager, the cost benefits offered by Stiefel are unparalleled. Their extensive inventory of solenoid valves and control panels are cheaper by fifty percent than OEM parts, but retain premium quality. In addition, their bulk discounts on annual maintenance contracts have saved us $10,000 a year.

Advanced Material Engineering

Advanced Material Engineering

Some of Stiefel’s more distinctive work includes silicone carbide ignition transformers (working at resistances of 1,400°C) and PEEK-sealed valves which are shut off from chemically reactive fuel systems. These materials minimize the frequency of maintenance needs, as in a Mexican refinery where our parts lowered annual replacement expenditure by 45%, and increase the lifespan of parts.
Global Certification and Compliance

Global Certification and Compliance

Parts of our boilers have CE, ATEX, UL, and CSA certification as fitting for use in regulated markets globally. For example, our explosion proof solenoid Valves EEx d IIC T6 approved for Zone 1 hazardous areas are suitable for LPG powered boilers sold in the EU and North America.
Data Driven Predictive Maintenance

Data Driven Predictive Maintenance

Using our IoT-enabled parts like sensors placed in actuators and valves, clients obtain intel concerning their parts’ health in real time. A Dutch dairy plant’s use of this data to predict nozzle wear and replace them proactively led to a 35% reduction in unplanned downtimes and improved their maintenance budget.
