NORD DRIVESYSTEMS presents a package of drive technology innovations for high hygiene applications. A new family of two-stage helical bevel gearboxes has been designed for easy and residue-free cleaning. The washdown gear units feature no indentations or dead spaces where dirt or liquids could accumulate. Due to especially smooth surfaces, cleaning liquids can easily wash off in all installation positions. The systems withstand frequent intense, aggressive cleaning with acids and alkaline solutions. Manufactured from die-cast aluminum, they resist corrosion far better than steel models.
The family comprises five sizes with torques between 90 and 660 Nm. All models are available as an open, especially lightweight version or enclosed. Additionally, NORD introduces NSD tupH, a sealed surface conversion system that makes aluminum drives as robust as their stainless steel counterparts and is a thousand times as durable as anti-corrosion paints. Combined with stainless steel standard parts, stainless steel output shafts, and food grade lubricants, NSD tupH drives are the optimal solution for applications with stringent hygiene requirements. Drawing on its extensive range of high-performance and efficient drive technology for the food industry, NORD realizes a variety of solutions for pumping, mixing, cooling, transporting, and packaging food articles. For a brewery application, for instance, industrial gear units were custom-manufactured. The product range includes hygienic, reliable wet cell versions of geared motors. Special feature modifications available for the complete range include extended temperature operation, protective finishes and special lubricants. A highlight from the electronics division is the versatile line of SK 200E frequency inverters for distributed installation, which have proven themselves in many applications. Four sizes from 0.25 to 22 kW are available. Functionally, the devices can adapt to a diverse range of requirements. Options include AS-Interface and the safety function “Safe Torque Off”. Special variants for pump operation feature two analog inputs that allow for variable speed adjustment and can actively and autonomously control process values. The cost-efficient SK 200E inverter series also includes special variants suitable for conveyor applications. A microsite at http://food.nord.com provides the food industry with a quick overview of the full range of services and sector-specific solutions from NORD. The manufacturer will show its systems and solutions for the food, beverage, and packaging industries at the Anuga FoodTec trade exhibition on March 27-30 in Cologne, Germany, in Hall 10.1, at Stand B054.
