20 Inch Big Blue Descaler with steel bracket (including 5kg Siliphos Crystals)

The DESCALER20 is a high-capacity water conditioning system designed to reduce limescale and corrosion in homes or buildings with higher water usage. It features a robust 20-inch Big Blue filter housing filled with 5kg of Siliphos crystals and is mounted securely using a durable steel powder coated bracket. This system is ideal for households or small businesses using municipal or borehole water, offering chemical-free protection for pipes and water-based appliances.

Key Features:

• Reduces limescale build-up and corrosion throughout the plumbing system

• Pre-filled with 5kg of premium Siliphos crystals for long-lasting protection

• Extends the life of geysers, dishwashers, washing machines, and kettles

• Suitable for use with municipal and borehole water (borehole applications require a submitted water analysis)

• No salt, electricity, or backwashing required

• Installs neatly with a steel powder coated wall-mount bracket

• Low-maintenance system—just top up crystals as they dissolve

How It Works:

• Siliphos crystals prevent calcium and magnesium ions from forming hard scale by sequestering them in the water

• The treated water flows over the crystals inside the chamber, reducing limescale and corrosion without affecting water taste or quality

• Especially useful in older plumbing systems prone to corrosion or homes in hard water areas

Specifications:

• 25 mm female inlet and outlet ports (1 inch BSP), easily adaptable to other pipe sizes

• Pre-filled with 5kg of Siliphos crystals

• Optimal flow rate: 1500 litres per hour

• Maximum flow rate: 3000 litres per hour

• Maximum pressure: 6 bar

• Crystals dissolve over time and must be topped up depending on usage and water quality

• In rare cases with extreme lime content, the crystals may melt together and cause blockages—if lime levels are excessively high, a water softener may be more suitable

What’s Included:

• 1 x 20-inch Big Blue filter housing

• 5 kg Siliphos crystals in a refillable media housing (pre-filled)

• 1 x Steel powder coated mounting bracket with screws

• 1 x Wrench for housing maintenance

The DESCALER20 is the ideal solution for larger households or light commercial applications needing a reliable, eco-friendly way to prevent scale and corrosion. Easy to install and maintain, it offers long-term protection for your plumbing and appliances without the need for harsh chemicals or electricity.

Disclaimer: Big blue filters are intended for fine filtration and limits apply to water quality and quantity. Have your water tested before installing a big blue filter to ensure that it is the right solution. It is important to note that the volume of water put through the unit as well as the quality of the water will greatly influence the lifetime of the filters.
