Hydrohermetics sealing is a specialized sealing system for Flottweg separators. It creates a liquid barrier between the product chamber inside the bowl and the surrounding environment. This sealing system uses degassed water, which prevents the ingress of oxygen while simultaneously reducing the escape of product-related gases. For applications with particularly high product protection requirements, the seal water can additionally be enriched with CO₂. This further minimizes oxygen ingress and achieves an even higher level of product protection.
Unlike mechanical sealing systems, the hydrohermetics system operates without contact and is therefore wear-free. This increases operational reliability and reduces maintenance requirements.
In many industrial processes, preventing oxygen from entering is critical to product quality. Food and beverages—especially beer—as well as fermentation products and biotechnology products are particularly sensitive to contact with oxygen. Even the smallest amounts of oxygen can impair taste, quality, freshness, or shelf life. Hydrohermetics sealing therefore supports a gentle separation process and creates optimal conditions for high-quality end products. In the brewing industry in particular, they help minimize oxidation processes and preserve the sensory quality of the beer.
Hydrohermetics sealing has been a proven feature of Flottweg separator technology for many years. The system combines reliable product protection with a wear-free and low-maintenance design.
Thanks to continuous technological advancements, even the most stringent requirements for oxygen minimization and product protection can now be met. As a result, hydrohermetics plays a key role in ensuring stable processes and consistently high product quality.
