Cummins Inc., a global power technology leader that designs, manufactures, distributes, and services a broad portfolio of power solutions, has revealed a revitalized Series 850 Holset Turbocharger.
The turbocharger, said Cummins, meets or exceeds the unique product specifications and uptime requirements of its global customers and offers a new compressor stage that provides a more efficient and aerodynamically focused product. The Series 850 caters to high-horsepower customers with engines ranging from 15L to 95L (15L to 25L per turbocharger).
Features of the Series 850 Holset Turbocharger:
- High-Pressure Ratio Compressor: Like its predecessor, the Series 850 includes Cummins’ advanced High-Pressure Ratio Compressor (HPRC) technology, a product enhancement the company released in 2020. The compressor features:
- +7 points of efficiency at a 4.5:1 pressure ratio from the current product;
- >6:1 pressure ratio (Vaneless or Vaned);
- 25 to 40 percent power uprated is achievable;
- Increased altitude capability;
- ~5 percent improvement in BSFC (simulated) when matched with HPRC
- New inverse impeller:
- Bespoke design optimized to meet higher performance with improved durability
- Vaned and vaneless diffusers:
- The vaneless design offers enhanced map width at higher pressure ratios, whereas the vaned design offers efficient higher pressure ratio capability with the flexibility to improve usability by altering vane designs.
- Thin-wall stainless steel compressor cover:
- The stainless steel compressor cover offers weight reduction against the cast iron version, which is attributed to the investment casting process used to cast thin-walled castings.
“Our Holset Turbochargers are continuously incorporating new technology to improve our products and exceed performance expectations for on-and off-highway customers. With additional altitude capacity, improved product efficiency, and higher power density, the Series 850 is designed to meet emission requirements and drive value for customers,” said Lalitkumar S. Suryawanshi, the Director of High Horsepower Products at Cummins.
The upgraded Series 850, manufactured in Huddersfield, England, is available now and caters to a wide range of customer off-highway applications, including power generation, agriculture, mining, oil and gas, rail, construction, and marine.
