NORD drive solutions for primary packaging

With NXD tupH®, drive solutions also withstand the various cleaning intervals in wet product-contact areas. Image: NORD DRIVESYSTEMS

Process advantages for the spray zone with NXD tupH^® 

Comparable to stainless steel when it comes to hygiene and corrosion resistance, more efficient when it comes to space requirements and scalability: With the NXD tupH^® surface treatment, NORD DRIVESYSTEMS opens up new planning options for primary packaging. Aluminium drive solutions are more compact and provide thermal benefits as well as – thanks to NXD tupH^® – effective protection against moisture and aggressive cleaning chemicals in intensive cleaning intervals.

With NXD tupH^®, NORD DRIVESYSTEMS puts drive technology with aluminium housings into wet product-contact areas. The combination of surface treatment and high-performance sealer provides a particularly hard and non-porous surface that can be cleaned quickly and hygienically. Even after numerous cleaning cycles, the sealer does not flake off and thus does not enter the products to be packaged. Thanks to the surface treatment, the protective effect remains unchanged even with minor damages. A long-term test using Ecolab cleaning agents has proven the resistance to cleaning chemicals. Decisive for use in wet product-contact areas of primary packaging: NORD drive components with NXD tupH^® surfaces are in accordance with the requirements of the FDA, EU and Switzerland as well as the MERCOSUR states.

More compact and more scalable
With NXD tupH^®, NORD refines the hygienically designed drive components of its wash-down modular product system and reveals process advantages in some additional application areas of primary packaging. For example, drive solutions with aluminium housings can be designed more compactly than with stainless steel, as aluminium is more lightweight and has a significantly higher thermal conductivity. The modular product system furthermore allows the drives to perfectly fit into the machine. All these factors result in reduced space requirements and enable flexible scalability of the system.

Decentralised and suitable for servo
With the NXD tupH^®-capable NORDAC ON PURE, the solution provider will soon reveal the advantages of decentralised drive electronics for wash-down areas. Ethernet on Board, hybrid cables and daisy chain technology enable efficient and hygienic topologies. This makes the inverter easier to clean and significantly more streamlined than conventional decentralised wiring. Furthermore, its integrated POSICON software allows for the creation of travel profiles for non-complex servo applications in packaging. This includes control functions such as synchronism and flying saw that are used, for example, when separating and sealing during flow wrapping.

Economic alternative to servo
Wherever servo gear units are oversized in the primary packaging line, NORD offers helical, helical bevel and worm gear units as an economic alternative. With IEC, NEMA and servo adapters from the NORD modular product system, they can be combined with servo motors from various manufacturers. And here again: NXD tupH^® makes the drive solutions resistant and durable.
