Hot technology for hot boards: Innovative KSB technology for handling thermal oils

Producing particleboard requires high temperatures – KSB and its high-performance heat transfer fluid pumps make sure the thermal oil used is transported smoothly.

1. Customer

Kronospan Schweiz AG is part of the Swiss Krono Group, a leading company specialised in producing and refining wood-based materials. The company's facilities in Menznau produce particleboard and fibreboard for furniture and interior finishings as well as high-density fibreboard (HDF) for laminate flooring. Since 1969, when the first chipboard left the factory, the company has trusted in KSB pumps for handling thermal oils – a long partnership that is still going strong.

2. Project

Producing wood-based chipboard is quite a hot process: First, the wood chips are dried in a rotating drum with hot gases at temperatures around 350 °C. After the dry chips have been bound together, they are pressed to form the actual board. This requires temperatures of up to 285 °C.

To be able to use such high temperatures continuously and evenly, thermal oils are used. At Kronospan the oil is heated up using recycled wood, which is burnt in a special wood energy production system. Once the oil is heated, it is transported to the production facility.

KSB Etanorm SYT heat transfer fluid pump

3. Challenge

What was special about this project were the tough demands the production process places on the thermal circuit – especially the high temperatures that would be enormously challenging for any pump system. The fluid to be handled was mineral thermal oil of the type Transcal N, which is characterised by a high thermal stability and a good thermal conductivity. Transporting such thermal oils in these temperature ranges requires pumps of extraordinary robustness and maximum operating reliability.

4. Solution

In the Kronospan facilities in Menznau, located in the Lucerne hinterland, more than 50 heat transfer fluid pumps made by KSB carry out their responsible task. The heating and control circuits alone are fitted with 40 Etanorm SYA and Etanrom RSY pumps of various sizes. In the main energy centre, which was inaugurated in February 2010, the modern plant is equipped with another six Etanorm SYA and three Etanorm RSY pumps as well as pumps of the new KSB type series Etanorm SYT. Another four Etanorm SYA and Etanorm RSY pumps were installed as part of modification work at the heat energy supply system in the production facilities.

When the heat is on, experts are needed – for example Etanorm SYT with the new VenJet® venting feature. These systems are perfectly prepared for their hot and oily work. KSB’s patent-pending VenJet® venting contour ensures that the gases contained in the fluid handled can be separated and collected in a different chamber. This allows them to be released in a controlled manner via a screw plug. The pumps are especially sturdy in design and remain torsion-resistant, also in hot temperatures. Further benefits of Etanorm are its low heat transfer to the bearing bracket, low maintenance requirements and, as a result, its excellent operating reliability.

The pilot pump is an Etanorm SYT 150-400 with a flow rate of 470 m³/h, a head of 46 m and a remarkable efficiency of 83.8 %. For decades KSB service specialists have been supporting the site with great care to prevent failures and costly downtimes. The proven benefits of Etanorm SYT are more than ready for the future.

Welcome cooling for high-volume printing

In order to achieve sustainable improvements in its environmental performance, the web-fed offset printing company WKS Kraft Schlötes implements ISO 50001-compliant energy management. This involves continuously checking all processes for energy efficiency. These checks revealed that the water cooling system of the commercial printing press for brochure printing is an energy-intensive process. KSB won the contract to provide new pumps capable of achieving competitive energy and cost savings.

Keeping cool in the face of sweet temptation

For many people, chocolate is more than just one of life’s sweetest temptations. The complex machinery required for the industrial production of this luxury food item also presents engineers with major challenges. In an ever-tightening market, traditional companies in particular, such as the Ludwig Weinrich chocolate factory, need to rise to current economic and ecological challenges. To do this, they need reliable partners.

KSB Guard saves industrial park from compressed air failure

KSB ensures that the Kalle-Albert Industrial Park in Wiesbaden, Germany, is reliably supplied with compressed air. Our customer Infraserv and its subsidiary ISW know they can rely on KSB’s expertise: Etanorm pumps equipped with the KSB Guard monitoring unit. They keep the vital compressed air system running reliably and continuously cool the operating temperature.

And KSB Guard has already paid off very successfully: it helped to detect the looming threat of bearing damage at an early stage and prevented major failures.

More transparency – with KSB Guard

Even high-quality pumps can sometimes experience malfunctions whose exact cause can only be determined by a long-term diagnosis. External factors are often to blame, and these can only be identified if the affected pump is monitored over a longer period of time using suitable sensor technology. KSB Guard has been developed to determine a problem’s cause so that remedial action can be taken.
