Benefits of Stifel’s Burner Parts

Stiefel's components are specially designed to have great quality ensuring durability for an industrial purpose. The carbide tipped nozzles heightened resistance to abrasion in biomass burners by five times compared to standard stainless steel. This also decreased maintenance frequency by eighty percent in a Swedish pellet plant. Inconel combustion chambers in stiefel industrial burner kits outperform generic parts by three years enduring 1,600 degree celcius in a steel mills reheating furnace. Every part from solenoid valves to ignition electrodes are tested with 10,000 cycle load tests and helium leak checks to ensure compliance to ISO 9001 and operational reliability of 99.9%.

Value Adding Maintenance With Global Logistic Sponsorship

Repair time on our premix burners is already less than 2 hours due to modular design, and preorder bulk kit valves, seals, and coils for Canadian district heating plants, saving them 25% on annual maintenance. With our 12 global warehouses, same day shipping on ignition electrodes and pressure regulators is guaranteed for clients with 24/7 technical support and a library of instructional videos. Japanese food processors using our parts rapid-response delivery service for emergent requests have reported a 60% reduction in standby time.
