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 catalog consists of every part that guarantees proper and efficient operation of the boiler. Our ceramic seat butterfly valves provide bubble tight seal (leak rate ≤0.05 cc/min) in high pressure systems, while oil pumps with hardened steel gear handles viscous fuels (up to 500 cSt) in waste oil boilers. Safety parts like pressure relief valves and flame sensors are compliant with ISO 13489 standards which ensures safe operations even in dangerous conditions. For one maritime boiler using our parts, the service team due to the anti-corrosive coatings and precision overhaul machining took replacing the parts every 6 months to every year. Stiefel caters to customers who need single replacement parts and those looking for full system overhauls.

Frequently Asked Questions

What warranty and after sales support do Stiefel’s boiler parts come with?

Defects on materials or workmanship are covered by a warranty of 2 years for all standard parts. Warranties on custom components are adapted to the requirements of the application. Our after-sales team offers elaborate manuals on guide’s remote troubleshooting by video call, maintenance training at the site, and other support activities. A Japanese food processing plant received emergency support for a faulty solenoid valve within 4 hours which helped enabled the plant avoid prolonging the already critcal production run.

Dependable Parts for Outdated Boiler Systems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.

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.
