400 US gallon HDPE Royal Water Tank – Vertical Tank

Built for varied everyday and project-based water needs, this Royal HDPE model combines thermal protection, food-grade contact material and a durable 4-layer structure. Each layer performs a defined role, helping protect stored water from external heat, UV exposure and internal biological growth across residential, commercial, outdoor and supplementary-storage settings.

Key Features

• 7-Year Warranty: Every Royal HDPE water tank is backed by a 7-year warranty, providing longer-term confidence in the selected product.
• Grey Thermal-Insulation Layer: A dedicated grey polyethylene insulation layer helps reduce heat transmission from the surrounding environment towards the stored water.
• 4-Layer HDPE Construction: Manufactured using German blow-moulding technology, the Royal water tank uses 4 functional HDPE layers that combine external, light-shielding, thermal and internal protection.
• UV-Stabilised and Sun-Shield Protection: The UV-stabilised exterior supports the tank during outdoor sunlight exposure, while the black sun-shield layer helps limit light penetration through the tank wall.
• Food-Grade Inner Layer: The innermost food-grade HDPE layer provides a suitable contact surface for potable-water storage and water used throughout the home.
• Fungal and Bacterial Growth Protection: The protective black layers are designed to help prevent fungal and bacterial growth inside the tank, supporting better-protected water storage.
• Smart Air Vent: A built-in smart air vent integrated into the lid supports internal airflow and is designed to help reduce heat accumulation inside the tank.
