. In most applications, the temperature of the medium needs to remain constant at a specified value irrespective of variations in ambient temperature. Several constructions are available. Heated hoses are suitable for environments from -40°C to 80°C and can be used in explosion-proof zones 1/21 and 2/22, if required. A heated hose consists of a flexible hose, through which the media is pumped. This hose determines the resistance against temperature and chemicals. A

Heated hose are generally specified by required inside diameter, working pressure, operating conditions, voltage, temperature sensor and hose fitting. Heated hoses are now available for use around the home and farm. Commonly used on farms to get water to livestock in northern climates during the winter.
