Jumbo Tankby Astral Industries Limited

Why Jumbo

Built to outlast the sun.

A tank is bought once and judged for years. What follows is what goes into a Jumbo Tank, and what the double-layer wall is actually for.

Why Jumbo

Two layers. Two different jobs.

Every Jumbo plastic tank is moulded as a double-layer wall, each layer doing a different job. Hover either one below and the diagram picks it out of the cut.

Tank wall, cut through

  • Outer layer

    Black, for UV protection and weather resistance

    UV stabilised, so the wall keeps its strength under the Kenyan sun — and opaque, which is what keeps algae from taking hold inside. This is the layer you see, and the one that takes the knocks.

    Know More
  • Inner layer

    White virgin material, food grade and anti-algae

    Virgin material, not regrind — the only surface your water touches. Smooth enough that residue has nowhere to sit, and bonded to the outer layer during moulding rather than glued on afterwards.

    Know More

Two layers. Two jobs. One strong tank.

  • Air ventilation

    Vented so the tank breathes as water moves in and out.

  • Food grade

    Non-toxic inner surface for household water storage.

  • UV stabilisation

    The outer wall is built to sit in direct sun.

  • Built stronger

    Two bonded layers instead of one moulded wall.

  • Low maintenance

    A smooth interior keeps routine cleaning simple.

Growing with Kenya.

Astral Industries Limited designs, manufactures, installs and maintains water storage and fabrication solutions - moulded tanks, tank structures, steel structures, fuel tanks, hot water cylinders and panels. What started as a regional operation now reaches customers across Kenya, and the company supports community work around water access in arid areas and the agricultural sector.
