Cummins Turbo Technologies (CTT) offers advanced improvements to the Series 800 Holset Turbocharger with an all-new compressor stage. The Series 800 Holset Turbocharger from CTT offers a world class product for its global customers that focuses on delivering performance and uptime in high-horsepower industrial markets.

Already a key component of CTT's product catalogue, the Series 800 Turbocharger takes a leap forward and has been revitalized to deliver significant improvements in performance, flow range, temperature capability and seal robustness. The Series 800 turbocharger is designed for engines ranging from15L to 28L, but can be paired with two or four additional turbochargers for engines ranging from 28L up to 100L.

The Series 800 turbocharger has achieved its best-in-class results by introducing technological advancements like:

• High Pressure Ratio Compressor 
• Extended flow range 
• Thin wall stainless steel compressor cover
• Lead free bearings option
• High temperature capable turbine housing option 
• Improved seal and joint robustness

For the very first time we are introducing the High-Pressure Ratio Compressor (HPRC) technology on Series 800 Turbocharger. This product architecture increases flow range capability by up to 25% and is optimized for pressure ratios of up to 6.5:1. These capabilities have allowed our customers to uprate engines by 20-40% without the need to move to a 2-stage architecture. We have also enabled additional altitude capability for many applications. The HPRC offering also improves our product efficiency. These gains enable air handling architectures which have resulted in 5-7% BSFC improvements for existing applications during engine simulation work. 

The new Series 800 Holset Turbocharger is available with a thin walled stainless-steel compressor cover, enabling us to increase capability without adding to our weight or space claim. We also offer lead free bearings, high temperature capable turbine housings and have increased robustness of our joints and seals.

At Cummins, our continued investment in research and development enables us to engineer new solutions for this market. We are currently in development of an integrated electronic wastegate for optimal flow control as well as focusing on turbine stage efficiency improvement.  

"We are excited to be offering new innovative technologies to increase the capability of the HE800 product line without needing additional space claim. We have been able to leverage our technical engineering expertise and advanced simulation analysis to provide critical air-handling features such as higher-pressure ratios and improved efficiencies while offering more product robustness." commented Brett Fathauer, Executive Director - Engineering and Research. 
The performance results of the upgraded Series 800 Turbocharger have been met with enthusiasm from off-highway customers who describe the Holset product as "class leading.”

The team at CTT has used the latest design practices to ensure this new product is superior to competition and drives value for customers. The upgraded Series 800 Turbocharger is available now and caters to a wide range of off-highway customer applications including power generation, agricultural, mining, oil & gas, rail, construction and marine. 

"At CTT, we continuously work to improve our products for on- and off-highway customers. The new Series 800 turbo is a class-leading product which exceeds performance expectations and provides excellent value for our customers around the globe," commented Matt Franklin, Director - Product Management and Marketing at Cummins Turbo Technologies.
