Stiefel's Boiler Parts Benefits.

Complete Compatibility With Major Boiler Brands

We primarily focus on making parts for boilers that are 98% compatible with top-end manufacturers such as Riello, Honeywell, and Baltur. Our silicon carbide core ignition transformers are used in replacing legacy components in industrial boilers and achieve 1,200°C furnace temperatures, emitting 35kV sparks. A paper mill in the U.S. reduced their repair costs by 30% after incorporating our OEM-quality flame sensors and fuel filters which were effortlessly designed for use with existing Riello burners. It does not matter whether you seek parts for commercial condensing boilers, or heavy-duty industrial systems, our cross-reference guide aids in the swift identification and installation of parts, seamlessly.

Not only do Stiefel's nozzles prevent the injection of unwanted gas emissions into the atmosphere, they maximize combustion efficiency. Dual fuel nozzles allow for gas and oil to be interchanged as required, while integrating a timed switch to be automatically set to turn on when required. Oil nozzles became an asset to the paper mill, dropping unburned ash carbon from 12% to 4%. Thermal efficiency achieved by gas nozzles stemmed from premixing technology, attaining 98% thermal efficiency with NOx emissions at a maximum of 30 mg/nm³. The nozzles’ designs inhibited carbon emissions while allowing the paper mill and fuel combustion system to maintain high standards of efficiency and reliability. Changes now take less than an hour per nozzle, making maintenance as simple as replacing the tips.

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Dependable Parts for Outdated Boiler Systems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.
