Polyethylene-Rotomould Water Tanks

Tietan polyethylene (Rotomould) tanks are safe for storage of water for human consumption. It has a capacity ranges from 100 US gallon to 5000 US gallon’s. It is vigorously designed to withstand both hydrostatic and dynamic water pressure.

Our water tank is tested in an accredited test laboratory in United Kingdom as per BS 6920 – 2000 up to 50°C.

Tietan polyethylene tanks are manufactured by means of rotational molding process under strict quality control and hygienic condition.

Tietan is certified to ISO 9001 – 2000 in which quality system has been organized to comply with international standards.

Our tanks are produced with 100% virgin resin, which meets FDA specifications for potable water. Our tanks are warranty for 12 years against any manufacturing defect.

Special Features of Tietan Rotomould Tanks

  • Tietan rotomold tanks are strong, durable, high impact resistance, hygienic, economical and maintenance free.
  • Our rotomold tanks are built-in several circumferential ribs help to resistance hoop stress and make the tank strong enough to withstand the water pressure and load.
  • Tietan Rotomold Tanks are made from linear low density polyethylene (LLDPE). Food grade (FDA Approved), these materials comply with recommendation and statutory regulations in the USA and most European countries regarding water tanks intended to come in contact with drinking water.
  • Tietan Rotomold tanks are UV stabilized and will not breakdown and to give a long service life under outdoor exposure in harsh weather condition.
  • Tietan Rotomold Tanks have been manufactured according to BS6920-2000 standards to ensure the best quality and suitable to store potable water.
  • Clean hygienic – exterior white UV layer prevent ingress of sunlight up to the inner layer which comes in contact with water, which prevents growth of algae and bacteria and thus maintain clean hygienic quality of water, also smooth inner wall is deterent to deposition of foreign particles on it which makes it easy to clean and maintain.
  • Lid (Cap) – threaded lid protect water inside the tank from ingrese of dust, dirt, insects etc. And keeps water safe and clean.
  • Inbuilt air vent provide fresh air circulation inside the tank.
