Compressors

The story of how X-Range transformed a whole industry

When Sperre began developing what would become the X-Range compressor, the starting point was clear: the market had changed, and so had the requirements.

It had been many years since Sperre had introduced a completely new compressor when the X-range entered the market in 2010. Vessels were becoming larger, operating hours were increasing, and expectations for efficiency, safety, and performance were rising


From concept to finished product

The development of X-Range was a long-term engineering effort involving internal specialists and external design partners from Inventas. Several concept phases were explored before the final direction was defined.

– We built multiple prototypes before landing on the final solution, says Asbjørn Klokk, Product R&D Manager at Sperre, who has been with the company since 1994 and knows the products inside out.

– Parallel processes were running at the same time. Calculations, simulations, and testing. Everything had to align.

Compressors for the maritime industry must meet strict classification requirements. Many component requires approval, and every function must perform reliably.

– If the compressor fails, the vessel can’t sail. Starting air is critical. That’s the reality, says Asbjørn.


Built for higher demands

One of the main drivers behind X-Range was the need for improved performance and cost-efficiency. Modern vessels have engines that demand more power. At the same time, owners expect lower lifecycle costs and predictable maintenance.

The solution was a modular compressor design with fewer movable parts. The result was measurable improvements:

  • 25% fewer wear parts

  • 50% less installation time

  • 10% lower energy consumption

Reducing the number of components not only lowered production complexity but also improved reliability and reduced maintenance requirements.

– We needed a compressor that could operate at higher speeds and deliver more power, while maintaining long-term durability, says Asbjørn.

Today, Sperre offers up to a 30-year spare parts availability on its compressors, reflecting confidence in long-term design and material choices.


Design driven by function

The Enclosure and design of the X-Range is one of its most recognisable features. But it was never developed primarily for aesthetics. Cooling principles and safety considerations were the main thoughts behind the design. The fully enclosed construction eliminated hot surfaces and protected both operators and critical components.

– No hot surfaces means improved safety on board. That was important when designing a new compressor, he says.

At the same time, the distinctive X-shape gave the compressor a recognisable identity – something unusual in a traditional product category.

– When designing the compressor, we also wanted it to stand out and be recognisable. I believe we achieved that, Asbjørn adds.

In 2009, X-Range was awarded the Red Dot Design Award, competing across industries. The recognition confirmed that functional industrial equipment can combine engineering precision with strong design execution.

More than a product launch

The introduction of the X-Range had significant consequences for Sperre. It strengthened the company’s position in the market and supported further growth. It also led to internal development, including improved control systems and the establishment of a dedicated aftermarket department.

– We needed a new product to continue developing as a company. X-Range became that product, says Asbjørn.

Today, the compressor continues to evolve. Regulatory requirements are becoming stricter, vessel technology is advancing, and expectations are increasing. As a result, development never stops.


Lessons for the future

Quality cannot be rushed, and that became an important principle during the development of the X-Range.

– Product development often takes longer than expected. Extensive testing is required, and we take that seriously. We cannot release a product that doesn’t perform, Asbjørn says.

Looking ahead, Sperre continues to focus on low-pressure systems and on strengthening its position as a system supplier, delivering integrated solutions with full control over performance and reliability.
