Gamrat HYDRO

Gamrat Hydro is a polyvinyl chloride hose with helical reinforcement, used to carry drinking water and other liquids, and solid materials.

 

The wall of a hose consists of green softened PVC material supported by a helix of hard PVC material. Its inner surface is smooth.

The elements of Gamrat Hydro system are suitable for operation at temperatures from -10°C to +55°C.

 

Quality requirements:
PN-EN ISO 3994:2014,
TWT-ZPR-01/2013.

 

Hygienic assessment:
PZH Nr HZ/17521/01.

 

Below, there are given limit values of a bending radius, at which the Gamrat Hydro hoses do not deform. The test has been carried out in accordance with EN ISO 1746. When pressure tested at 23°C, the elements of Gamrat Hydro system do not fail due to collapse or fracture at pressures up to 65 kPa (absolute pressure of 35 kPa).
