Pharma showdown: Dynamic CLC vs. Dynamic Cleanroom

Over the past few months, we have added several new industrial hoses to our stock, and as always, this is by far the most popular product category among our customers. In particular, new models have been added to our range of pharmaceutical hoses, and two of them stand out in particular: the Dynamic CLC and the Dynamic Cleanroom. It's fair to say that they set entirely new standards in terms of some of the most important properties for pharmaceutical and biotech production. 

But which of these two dynamic models should you choose? The answer to this question naturally depends on the specific requirements of your production. We provide an overview of the key properties of each model, giving you the best basis for making your final choice.

We call it “the king of corrugated” for good reason. Dynamic CLC is extremely flexible and can be a game-changer in production environments with very little space at the process plant. In addition to this property, it covers a wide temperature range from approximately -40°C to +150°C, depending on the medium. With an inner PFA liner, it supports frictionless transport of, for example, yoghurt, sauces, food oils and similar viscous products. Combined with a steel spiral, multiple layers of polyester reinforcement and built-in copper wires, you get a pharmaceutical hose that is both extremely flexible, mechanically robust and safe to operate in demanding production environments. 

Would you like to know more about what makes Dynamic CLC special? Then watch this video, where we highlight the 3 most important benefits of the hose. 

Are you facing requirements for maximum hygiene both inside and out? Then you should look for the Dynamic Cleanroom hose. Within our range, it is known as one of our universal hoses, as it is suitable for the high-hygiene transport of everything from foodstuffs to pharmaceutical products. The hose combines the technical advantages of PFA with a silicone cover, which is food-grade approved and resistant to external contamination. In practice, this means the hose can be in direct contact with your products on the outside. The silicone coating also adds extra heat resistance and maintains the hose’s elasticity even under demanding conditions with temperature ranges from -30°C to +150°C, depending on the medium. 

The key difference between Dynamic CLC and Dynamic Cleanroom lies in their construction. Dynamic Cleanroom is more suitable for the high-hygiene transport of medicines and foodstuffs, as it is not only food-grade on the inside but also on the outside due to its silicone cover. In other words, it may also come into contact with foodstuffs externally. On the other hand, Dynamic CLC has better mechanical properties, making it ideal for use on moving equipment.

To give you the best overview of the capabilities of the two models, we have listed the most important parameters in the table below. Both hoses are in a class of their own, and the choice should always reflect your specific process environment and installation requirements.

1. You have very little space around the filling equipment, and the hose must bend sharply without kinking: Here, the Dynamic CLC will typically be the obvious choice, as its corrugated construction and steel spiral provide extreme flexibility, even with repeated movements and high temperatures. The hose is designed for dynamic loads and is particularly suitable for filling equipment and other applications where the hose is frequently adjusted and moved during operation. 
2. You have an installation where the hose may also come into contact with the product externally: Dynamic Cleanroom is food-grade approved both internally and externally due to its silicone cover, and may therefore also come into contact with the product on the outside. It's a major advantage if the hose is located in open tanks, above filling areas or in other zones where spillage or splashes may hit the outside, and where you still need to be able to document hygiene and food contact. 
3. You have production lines with viscous or sticky media that need to flow as smoothly as possible: Here, the Dynamic CLC’s internal PFA liner offers a particular advantage, as the smooth, white surface ensures low-friction transport of media such as yoghurt, sauces, food oils and similar products. This reduces the risk of deposits and makes it easier to achieve complete emptying and effective cleaning between batches. 
4. You work in an environment with significant temperature fluctuations – e.g. from cold storage to the process area: Both hoses retain high flexibility at both low and high temperatures, but the Dynamic Cleanroom is specifically described as highly flexible even at both high and low temperatures, reinforced with a spiral and multiple layers of polyester.

We offer a wide range of pharmaceutical hoses, with the Dynamic series developed with a focus on high operational reliability, flexibility and proven quality. We advise service technicians and production managers daily on everything from the correct hose selection to installation, approvals and documentation. 

If you need help with sizing or selecting couplings, we can put together a complete solution with pharmaceutical hoses, fittings and accessories tailored specifically to your process.

A PFA liner is chemically inert and has an extremely smooth surface, which prevents media deposits and ensures frictionless transport. This makes it ideal for ultra-clean processes, as the material does not impart any taste, odour or particles to your product. 

PFA is chemically neutral and has an extremely smooth inner surface, which reduces friction and deposits in your flow. Whilst silicone is highly flexible, PFA offers superior chemical resistance, retaining its shape and maintaining performance when exposed to aggressive media. 

USP Class VI is one of the strictest testing standards for the biological reactivity of materials. When your hoses have this approval, it's your guarantee that the material is safe to use in contact with medical and pharmaceutical products without the risk of adverse tissue reactions. 

A pharmaceutical hose can only withstand CIP cleaning if the materials, temperature limits and chemical resistance are documented for the CIP cycles you use in your facility. You should therefore always check the data sheet for information on temperature and chemical resistance against your CIP agents. Both dynamic CLC and dynamic Cleanroom are designed for high temperatures and thermal stress, making them suitable for CIP and sterilisation cycles in food and pharmaceutical applications.
