Heating hose with integrated inner heat- er for drinking or waste water
HWI 19/25 series 80 °C
Frost protection hose for mobile water supplies in winter and under cold ambient conditions.
Applications Container settlements, stables, washing and cleaning plants, Christmas markets, catering, agriculture, road construction, construction sites.
The heating element of the HWI hose is located directly in the medium. This direct heating technique consumes a low level of energy. This hose no longer differs visibly or in its usage from an unheated hose. A mini- controller in its connector head keeps the temperature in the hose constant above freezing point. The water hoses are approved under BT-DVGW / KTW-A and may be used for drinking water applications. For service water applications, the HWI hose is also available without plastic - drinking water approval (KTW) and is thus more economical. The hose heater is to be connected by way of a fault current circuit breaker.
