Heating hose with vulcanised heating conductor
Approval for foodstuffs
HL 40 / 80 series40 °C / 80 °C
The HL foodstuffs hose stands out by virtue of its innovative construction. The heating element is spiral-wound on the NBR hose core and thus lies vulcanised in the inner hose material. This hose does no longer differs visibly or in its usage from an unheated hose, thus handling is simplified considerably. A temperature sensor is also integrated into the hose which measures temperature directly in the hose wall. Suitable for transporting fatty and non-fatty foodstuffs, as well as passing alcoholic and non-alcoholic beverages.

All the hose materials used meet the requirements (EC) no. 1935/2004 of the instructions from the Federal Institute for Risk Assessment (BfR) (Recommendation XXI, cat. 2) and FDA CFR § 177.2600 Approval for foodstuffs.
On request, we can also supply suction and pressure hoses with steel coil. Special hoses made of fluoropolymer (Viton) can be fabricated for higher temperatures. Connections with flanges, quick couplings or outer treads are also available on request.
A range of devices is available for temperature control. The line extends from the mini-controller with fixed temperature setting to convenient microprocessor controlled devices. See chapter Control technology.
