PREO flexible high pressure thermo heated hoses convey liquids maintaining their properties unaltered, thanks to the internal constant temperature. They are available in different models: standard and special versions (high temperature, with external water proof braid and with external rigid protective jacket for movement, with external reduced diameter, with inner exchangeable glue tube and with air tube for spray). They are suitable for all different models of dosing systems present on the market and are used in all industrial fi elds requiring high quality, resistance and careful control of the temperature. They are available with different nominal diameters of the internal hose (6, 8, 10, 13, 16, 20 and 25 mm), with lengths that differ from 0,4 up to 12 meters and with working temperature between 50 and 230°C, in order to grant the same application precision, safety and reliability in controlling all different fl ows. The connection end fi ttings are available in a wide range allowing the perfect hydraulic connection between applicator and gun. Manufactured in galvanized steel, on Customer's request they can be demanded made of other materials (brass, iron, stainless steel) and equipped with different threads (BSP, metric, J.I.C, ASA etc.), in order to fulfil any possible technical or production requirement.
Available in different diameters, it is obtained through the extrusion and sintering of Polytetrafl uoroethylene (PTFE). It resists also to particularly aggressive adhesives and to temperatures over 230°C (450°F).
Built in stainless steel 18/8-AISI 304, it assures protection and resistance to the working pressures.
It brings the inner hose made of PTFE in temperature and wraps it around. It is of variable power.
It detects the material temperature allowing its continuous control.
It maintains the temperature constant wrapping and protecting the resistance.
They grant the electric connection between machine and gun. They can be supplied in different typologies and models.
It helps to keep the temperature to the level required thanks also to the silicon foam with which it is composed.
Equipped with earth conductors, they supervise to the heating and control of the guns solenoid valve (24V).
It increases the mechanical resistance against heat, strokes, abrasions wear and handling. It is available in Polyamide or in water-repellent silicon.
The electrical connection takes place here. They can be rigid or made of silicon and thanks to their particular resistance, they protect the hoses ends.
They are manufactured with different threads and materials in accordance with the specifi c requirement and allow the hydraulic connection between machine and gun granting a perfect tightness in all circumstances.
