QuantiServ operates four Reconditioning Centres. They are located in Kruiningen (Netherlands), Dubai (UAE), Suzhou (China) and in Singapore. At all four, we offer two convenient options for our customers:

  1. Exchange Service: We send you a newly reconditioned QS50K piston, whereafter you return your worn one to us.
  2. Reconditioning Service: We recondition your existing piston, put on the QS50K coating and return it back to you.

Between them, our four Reconditioning Centres have so far produced about 2’000 QS50K pistons. We thank our existing customers for their continued support and look forward to serving new ones too!

“Manufactured Again”-Certification Renewed

Our reconditioning centres in Dubai, Kruiningen, Singapore and Suzhou have been Manufactured Again certified since 2018. This prestigious mark represents the quality, value, and sustainability of our reconditioning (remanufacturing) processes and has just been renewed for another year.

Let’s delve into how this renewal benefits both our customers and our commitment to sustainability:

  1. Quality Assurance: The Manufactured Again Certification ensures that our reconditioned products meet rigorous quality standards. By adhering to stringent processes and standards, we guarantee consistent excellence in our reconditioned goods.
  2. Value Proposition: Reconditioned products offer exceptional value. They combine like-new quality with reduced production costs, resulting in better prices for our customers. By choosing our certified products, customers make an economically savvy choice without compromising on quality.
  3. Environmental Impact: Sustainability lies at the heart of our journey. Reconditioning conserves embodied energy and reduces waste. For instance, reconditioning one large piston consumes about six times less resources than producing a new one! Our commitment to reconditioning and sustainability aligns with global efforts to reduce environmental impact.
  4. Customer-Centric Approach: By holding the Manufactured Again Certification, we demonstrate our dedication to customer satisfaction. Customers can trust that our reconditioned components are not only eco-friendly but also reliable and high-performing.

In summary, our renewed certification reinforces QuantiServ’s position as a responsible service provider, creating value for customers while simultaneously advancing our sustainability goals. Together, we’re driving positive change — one reconditioned component at a time.

More Than 1’000 QS50K Pistons Delivered – And Counting!

In 2019, following an extensive research and testing period, we have introduced the first QS50K pistons into the market. It was the beginning of a lasting success story: Ever since, we have produced and delivered more than 1’000 pieces, to many different customers.

These pistons are now installed all around the world, in ocean going vessels and in power plants. They are performing extremely well and achieve time between overhauls (TBO) that hitherto were unthinkable. The earliest QS50K pistons have accumulated well over 30’000 running hours and are still in service!

Benefits of the QS50K technology

With the introduction of the QS50K coating technology, QuantiServ has redefined the piston reconditioning process. This proprietary technology was developed by QuantiServ and offers the following important advantages:

    • Extremely durable, wear resistant coating, resulting in very long life-time / time between overhauls (TBO)
    • Fully automated process carried out by a robot, resulting in a top-quality product due to the robot’s very high accuracy, repeatability and consistency.
    • Faster than chromium plating, therefore shorter turnaround times
    • Less heat input into the piston, eliminating any residual stresses that over time could develop into cracks
    • Environmentally sound, non-toxic process

Availability

We offer the QS50K technology for any engine brand and for any cylinder bore above ø 48 cm. The QS50K pistons that we have delivered so far covered the bore range, from ø 48 cm to ø 98 cm. They were destined for engines manufactured by the big three OEMs, in an approximately 45%/45%/10% ratio.

At this moment, our recon centres in Kruiningen (The Netherlands) and Suzhou (China) are equipped with the required machinery to offer this product. Our large recon centre in Singapore will follow very soon.

To give maximum flexibility to our customers, we offer three different ways of working to chose from:

  1. Reconditioning on exchange. The customer gets a newly reconditioned component delivered from one of our four reconditioning centres. Once he has installed the component into his engine, he returns his old part to us.
  2. Reconditioning of the customer’s own part. The customer sends the component to be reconditioned to a QuantiServ reconditioning centre, where it undergoes professional reconditioning after which it is returned to the customer.
  3. Straight sale. The customer purchases a reconditioned piston from us, without returning an old one.

We can apply the QS50K coating to pistons that are undergoing full or partial reconditioning.

Full reconditioning

The entire top surface and ring groove area is first machined off and then rebuilt by robotic MIG or SAW welding. Thereafter, the piston undergoes final machining before the QS50K coating is applied to the ring grooves. The last step is grinding of the ring grooves, which completes the full reconditioning process.

If it is requested by the customer, then we can coat the top of the piston by a protective layer of Inconel. This can be a good solution for engines that suffer from excessive hot corrosion at the piston top.

Partial reconditioning

If only the ring grooves are worn and if a piston is in otherwise good condition, then partial reconditioning is possible. A precondition is, however, that none of the ring grooves has worn so much that not only the chromium layer but the steel substrate itself has worn. In this case, partial reconditioning is not possible and full reconditioning is the only remedy.

During partial reconditioning, any remaining chromium is removed before the QS50K layer is applied to the ring grooves. All mating surfaces will be skimmed, to remove any signs of fretting corrosion and if there are small internal cracks, then these will be repaired too.

Our reconditioning centres

We operate four reconditioning centres that are strategically located along major shipping routes: Singapore, Kruiningen (The Netherlands), Suzhou (China), Dubai. Each of the four centres carries a large inventory, so it can offer components on exchange in addition to reconditioning the customer’s own part. Both ways of working are available, it is entirely the customer’s choice.

Our reconditioning centres are the most modern ones within our industry. Welding and QS50K coating is typically performed by robots and machining is done on numerically controlled (NC) machines.

Flywheel Teeth Dentistry on a Container Ship in Hong Kong

 

Our in-situ specialists from QuantiServ Dubai have just completed another flywheel repair. This time it was for a very large European owner, on one of their large container ships with a 12-cylinder, 96-bore engine while on anchorage in Hong Kong. Our specialists machined off two damaged teeth and installed an insert, which they had pre-fabricated at their workshop before boarding the vessel and which they sent on board jointly with the in-situ tools.
The total work took 42 hours – three long days of work – and the result is something that they can be very proud of!
