Accelleron has received its ten-thousandth order for the A100-L/A200-L turbocharger series. First introduced in 2009 and expanded in 2013, the low-speed turbocharger series has since become the most widely selected solution for marine two-stroke engines, recognized for its strong performance, reliability and contribution to energy efficiency in the shipping industry.

Accelleron A100-L/A200-L turbochargers are designed for low-speed marine two-stroke engines, in applications ranging from 3,000 kW to 28,000 kW. That wide power range means they are widely used across several core vessel segments in the global merchant fleet, from bulk carriers and tankers to LNG carriers and ultra-large container vessels.

The exceptionally wide compressor maps and advanced turbines that are a hallmark of the series mean that, despite being designed more than a decade and a half ago, they are still helping ship operators react quickly to volatile market conditions. Several cruising modes are enabled by those features, from highly efficient slow steaming to peak power via high-pressure tunings.

As successors to the widely used TPL-B series (launched 1999), the A100-L (launched 2009) and A200-L (launched 2013) are testament to Accelleron’s ethos of high performance, utmost reliability and continuous improvement. They weigh up to 30% less than equivalent TPL-B units, with volume flow increased by up to 15% – translating to a dramatic upgrade in power density from an already market-leading benchmark. Their popularity also builds on the TPL-B series, of which 6,900 units have been sold to date.

A100-L/A200-L operators have access to Accelleron’s global network of service experts, making overhaul and upgrade as effective and minimally disruptive as possible for busy merchant marine schedules. And with Accelleron’s digital tool Turbo Insights as standard, key turbocharger and engine performance indicators are clearly visible for ship operators, supporting effective maintenance and service interventions that optimize efficiency across the lifecycle.

Accelleron Global Head of Sales and Marketing, Medium & Low Speed, Benoit Viel, said: “Reaching 10,000 orders is an unprecedented success for a low-speed turbocharger series. We are deeply honored by the confidence that engine builders and shipowners have placed in Accelleron, which reflects our own commitment to deliver turbochargers that support their business goals – through efficiency, reliability and flexibility backed by exceptional global service.”
