A thoroughly clean solution

blueglobe CLEAN® Plus in mounted condition

Industries such as the food industry, pharmaceuticals, chemical and cleanroom technology set high standards for hygiene and ease of cleaning of production equipment. Therefore, high-quality stainless steel housings are used, for example. But what about the "clean" introduction of cables into these housings? Pflitsch offers a solution with the new cable gland blueglobe CLEAN® Plus, which impresses in terms of quality, operational safety, and ease of cleaning.

The requirements of the food industry for production equipment are very high in terms of hygiene. Attachments and contaminations must be minimized or ideally prevented according to DIN EN 1672-2:2009. Hollow spaces, gaps, and open threaded connections are therefore prohibited. Because residues can accumulate here and form bacterial nests, which are difficult to eliminate even with intensive cleaning processes. Manufacturers and suppliers of such production systems must therefore install components with minimized gaps. This is a particular challenge for cable glands, as conventional solutions often feature external threads and gaps between the compression nut and sealing insert as standard design.

Designed and certified according to EHEDG standards by BGN

The cable management specialist Pflitsch now introduces the hygiene cable gland blueglobe CLEAN® Plus, which meets the high hygiene requirements. Its design complies with the demanding EHEDG standard. Currently, BGN has confirmed conformity with the applicable test bases under the certification NV 13132: GS-NV-2 Food machinery and GS-NV-6 Hygiene (cross-industry). Other testing standards included hygiene requirements for food machinery from the 9th ProdSV Machinery Regulation and DIN EN 1672-2:2009.

The hygiene cable gland blueglobe CLEAN® Plus is designed without hollow spaces, gaps, or external threads and features smooth surfaces (roughness Ra < 0.8 μm) as well as rounded transitions to the sealing surfaces. The company uses high-quality stainless steel 1.4404/AISI 316L, which has established itself in the food industry. On a modern machining center, this material achieves a very smooth surface after turning processes and contours without edges or corners. This prevents dirt accumulation and bacterial nest formation.
All seals are made from TPU plastic (FDA 21 CFR §177.2600). They are suitable for contact with food according to EU Regulation 10/2011.

Few components – simple assembly

Even during installation, the blueglobe CLEAN® Plus impresses compared to standard market products: because this hygiene cable gland, with its few system parts, can be installed very easily without special tools. The gland body is either screwed into the housing wall or inserted into through-holes and fixed with a locknut. Then, the compression nut is placed onto the external thread, the cable is pushed through, and the compression nut is tightened onto the block. An elastomer ring seals the cable gland securely against the housing.

The blueglobe CLEAN® Plus is currently available in sizes M12 to M40 for cable diameters from 5 mm to 29 mm. It achieves high protection ratings of IP 66, IP 68 (up to 15 bar), and IP 69K and can be used at temperatures from -40 °C to +85 °C. The hygiene gland is also available as an EMC variant, blueglobe TRI CLEAN® Plus, with above-average damping values.

Closed and open stainless steel cable management systems

Pflitsch supplies additional components and solutions for electrical installations under hygienic conditions, such as closed cable management systems – also optimized for use in cleanrooms – or open grid cable ducts made of stainless steel, which allow cables to be routed safely through systems. Upon request, the company plans the necessary routing lengths, manufactures and assembles the cable duct components into ready-to-install assemblies, and installs them on-site at the customer's location.
