Vinitrell is a hose recently developed by Trelleborg Engineered Systems especially for the wine industry. This offers the superior benefits of a natural rubber product, while its advanced polymer coating allows it to move within the confined spaces of wineries as easily as a PVC hose.
"Rubber hoses have significant advantages over PVC products," says Christine Dhiersat, product manager for performance hoses. "These are the maintenance of pressure and flexibility over the whole of their operating temperature range and absorption of impact. Their disadvantage is that they are heavy and difficult to maneuver within wineries. Vinitrell, with its unique polymer coating, solves this problem and many wines in Bordeaux, Champagne, Languedoc-Roussillon, Rioja and Ribera Del Duero areas are already flowing freely through these hoses."
Vinitrell is manufactured from food-grade white natural rubber tube that is compliant to European and US standards, including FDA and the French Institute of Poitiers (IANESCO). Its special polymer-based coating has excellent friction characteristics, facilitating ease of movement.
With operating temperatures from -30°C to 80°C / -22°F to 176°F it is unaffected by fluctuations in these and is resistant to steam cleaning up to 110°C / 230°F for a maximum of ten minutes. Working pressure is 10 bar / 145 psi with bursting pressure of 30 bar / 435 psi and a maximum vacuum of 0.9 bar / 13 psi. In addition it is capable of withstanding most common cleaning media and contains no phthalate.
Vinitrell is available with inside diameters from 38mm to 75mm / 1.5in to 3in and in standard lengths of 20m and 40m / 65ft and 131ft. It can also be supplied with Trelleborg’s own-designed fitting system to fit all common connections and ensure full hygiene.
