For hygienically demanding applications, NORD DRIVESYSTEMS supplies aluminum two-stage helical bevel gear units in five sizes with a maximum torque of 660 Nm that are especially easy to clean. The washdown design is based on smooth inclined surfaces, transitions with large radii without dead spaces, and requires no assembly covers. Cleaning liquids wash off easily and completely from the surfaces, which also remain considerably cooler than those of conventional drives thanks to the special construction. The design is optimized, amongst others, for use in the food industry and complies with international guidelines and standards such as EHEDG, ANSI / BISSC, and ANSI / NSF. If required, the gear units can be fitted with double shaft seals. They can be ordered as open or closed frame versions with hollow or solid shafts.

Bargteheide – NORD DRIVESYSTEMS now offers a new range of worm gear units in a robust, one-piece UNICASE housing in five sizes with a maximum torque of 427 Nm. New, larger output bearings allow users to choose increased shaft diameters than the previously available series. In addition, the large bearings ensure a much extended service life. The aluminum permanent mould casting process was optimized for the SMI series, resulting in an especially smooth surface that prevents dirt build-up. Closed SMI worm gear versions are washdown-capable, and can therefore be easily cleaned along with other systems during plant cleaning processes. If required, these gear units are available with NORD’s NSD tupH surface conversion treatment which transforms their durability with up to seven times the hardness of the base aluminum material, providing excellent protection against acids and alkaline solutions. A synthetic long-life lubricant makes the worm gears maintenance-free during their entire service life. Equipped with oil gauge screws, the gear units are now also suitable for use in hazardous areas.

During 40 years of continuous around-the-clock operation, the tanks and vats in the Forst specialty beer brewery’s old brew house produced 25 million hectoliters of beer. Now, since brewing technology has progressed, especially with regard to energy aspects, the management decided to build a completely new brew house which was to operate highly efficiently, comply with the latest safety requirements, and produce the lowest possible emissions. The brewery in Algund, South Tirol, commissioned leading German companies to construct five large vats, complete with brewing technology and piping systems, a newly designed water supply, a malting plant with twelve silos, and three separate storage vats. NORD DRIVESYSTEMS custom-tailored all necessary drive units.

efficiency motors from NORD DRIVESYSTEMS

The SK 200E series is a highly versatile line of distributed AC vector drives customizable for specific applications. NORD has expanded the power capacity of the SK 200E up to 30 HP with the new size 4 drives. NORD is the only manufacturer that offers a motor-mount variable frequency drive at these ratings.

performance, washproof: New open or closed washdown versions of NORD's helical bevel gear units

In its cement plants and concrete factories in Croatia, geared motors of different performance classes are used. Heavy duty is no problem for the NORD products - they are ready for any challenge. That is why both companies have now completed a three-year-contract for the exchange of older drives.

SK 200E frequency inverters from NORD DRIVESYSTEMS are equipped with a proprietary system bus that allows for user-friendly, cost-efficient wiring in the field. Connected to the fieldbus or an Industrial Ethernet system via a bus technology unit that acts as a gateway, the system bus can link up to four frequency inverters. Thus, four drive units are connected to the higher-level communication system at one single point. All data is thus available at every diagnosis interface, i.e. users can access all data sets from every device connected to the system bus via RS232 interfaces at both the inverters and the technology unit.
