Trelleborg Citerdial – the dairy hose for milk collection and liquid foodstuffs

The Trelleborg Citerdial is widely regarded as the benchmark among milk hoses: extremely flexible, hygienic and built for intensive daily use. From milk collection tankers and unloading bays to process and filling lines in the dairy plant — the Citerdial accepts the tightest bend radius without kinking. Available from Nexaparts in diameters from 25 to 150 mm, by the metre or as a complete assembly with fittings.

Why choose the Citerdial dairy hose?

Unmatched flexibility – accepts the tightest bend radius without kinking, ideal for daily connecting and disconnecting
Hygienic white inner lining – smooth, seamless food-grade natural rubber that does not promote bacterial growth
Insensitive to temperature changes – the advantage of rubber over PVC, staying supple even in winter
Non-marking, abrasion-resistant cover – blue, weather-resistant, keeps floors and loading bays clean
Resistant to common cleaning agents – and steam up to 110 °C (max. 10 minutes)
Phthalate-free and fully traceable through embossing with production week, year and batch number

Applications

The Citerdial was developed for milk: milk collection and transport by tanker, unloading bays at dairy plants, and stationary process and filling installations. The hose is also suitable for other liquid foodstuffs such as wine, beer, cider, fruit juice, vinegar and alcohol up to 50%. Not suitable for fatty foodstuffs and oils — choose the Alikler G2 or Alikler D for those. For beer at higher temperatures and pressures, the Beerdial is the right choice.

Certified food safe

The Citerdial complies with EU Regulations 1935/2004, 2023/2006 and 2024/3190, FDA 21 CFR 177.2600, the French regulation of 5 August 2020 and the German BfR recommendation XXI cat. 2. All migration tests have been carried out and approved by the independent French institute IANESCO. The hose is also certified free of animal-derived ingredients (ADI-free). Made in France.

Custom fittings: the UTS system

Nexaparts assembles the Citerdial with the Trelleborg UTS coupling system, suitable for all common connections: DIN, SMS, MACON, CLAMP (Tri-Clamp) and GUILLEMIN — including dairy couplings for milk collection tankers. The crimped connection has no retention zones between hose and fitting, leaving bacterial growth no chance. Every assembly features an engraved ferrule with assembly date, ID number and test pressure — fully traceable.

Cleaning and maintenance

The Citerdial withstands the common cleaning agents: hot water up to 90 °C (max. 30 min.), steam up to 110 °C (open circuit, max. 10 min.), nitric acid, phosphoric acid, chlorinated products, caustic soda, hydrogen peroxide (3% at room temperature) and peracetic acid (0.5% at room temperature). Before first use, fill the hose with warm water of 70–80 °C and leave it for at least 2 hours. A maximum of 2 cleaning cycles per day, always followed by thorough rinsing. Avoid stagnation, do not use internal high-pressure cleaning, and store the hose in a dark, cool place.
