FRP Vessel 1665 2.5″ – 10 Bar Composite Pressure Tank

The FRP vessel 1665 2.5″ is a high‑capacity, corrosion‑resistant composite pressure tank built to perform in a range of water treatment systems. This strong tank uses fiberglass‑reinforced plastic (FRP) and an inner polyethylene liner to resist rust and chemical damage. It supports pressures of up to 10 bar (150 psi) and features a 2.5″ top opening that accepts standard top‑mount valves, making media loading and maintenance easier.

Because this vessel combines durability with easy access and a robust design, it works well in many commercial, industrial, and residential water treatment applications where reliable service is essential.

Key Features & Benefits

• Durable Composite Build

  • The FRP construction offers outstanding corrosion resistance, so it remains strong and reliable even in harsh chemical environments. Unlike metal tanks, it won’t rust over time.

• 2.5″ Top Opening

  • The 2.5″ threaded opening is designed for compatibility with top‑mount control valves and makes it easier to add, remove, or replace filter media without specialized tools.

• High Pressure Rating

  • Rated for a maximum operating pressure of 10 bar (150 psi), this vessel can handle flow and pressure demands of many water filtration, softening, or RO pre‑treatment systems.

• Wide Media Compatibility

  • You can fill this vessel with various media depending on the system’s needs, such as:
    • Sand for sediment and turbidity reduction
    • Activated carbon for taste, odor, and chlorine removal
    • Resin for water softening
    • Multimedia blends for comprehensive filtration

• Easy Installation & Maintenance

  • Due to its relatively lightweight composite design (compared with steel), the vessel is simpler to handle and install. Compatibility with standard 2.5″ top‑mount valves keeps integration smooth.

Technical Specifications

How It Works

In water treatment systems, the FRP vessel 1665 2.5″ serves as the media housing where selected filtration and treatment media perform work. For example, sand media helps remove sediments and turbidity, while activated carbon reduces chlorine and organic impurities. When filled with ion‑exchange resin, the vessel supports softening by capturing hardness minerals.

Water flows through the packed media under pressure, and the vessel’s corrosion‑resistant design helps ensure long service life without rust or premature degradation. The 2.5″ opening allows for easy media loading and access for valve installation or maintenance.

Applications

• Commercial Water Filtration Systems — for sediments and chemical contaminants
• Water Softening — resin housing for hardness removal
• Reverse Osmosis Pre‑Treatment — protects membranes by removing particulates
• Borehole & Municipal Water Treatment — improves water quality before point‑of‑use
• Industrial & Residential Water Systems — adaptable to varied setups

This vessel’s design and specs make it suitable across many water treatment contexts where solid, pre‑filter media housing is required.

Installation & Maintenance Tips

1. Place on a level and secure base before adding media.
2. Match top‑mount controls to the 2.5″ opening for compatibility.
3. Flush media before use to remove fines and dust.
4. Check all seals after pressurization to ensure tight, leak‑free connections.

Routine checks help ensure your system runs smoothly and extends vessel life.

Conclusion

The FRP vessel 1665 2.5″ is a versatile, durable composite pressure tank that supports a range of water filtration and treatment purposes. Because it withstands corrosion, handles high pressure, and provides easy access for media and valve installation, it offers a reliable solution for residential, commercial, and industrial water systems that require solid, low‑maintenance media housing.
