Stiefel's Boiler Parts Benefits.

Enhanced boiler efficiency accrues with premium-quality components.

Stiefel’s boiler parts are unmatched when it comes to reliability and efficiency. Our solenoid valves made of 316 stainless steel and PTFE have a fuel containment leakage of ≤0.01 cc/min and a 10 million cycle lifespan which is essential for safe fuel control in high-pressure systems. For example, a German hospital’s boiler system upgraded to our double-block valves, which led to an annual leak reduction from 12 to zero. In a Swedish pellet plant, our biomass boiler tungsten carbide tipped nozzles get 5x the lifespan of standard nozzles, resulting in lowered maintenance downtime by 80%. To ensure compliance with ISO 17025, every part undergoes rigorous functional testing, which includes helium mass spectrometry and pressure cycling.

Dependable Parts for Outdated Boiler Systems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.
