PE conical salt tank – Softening system salt storage tank – Large capacity salt storage – Rotational molding – Durable and sturdy

PE Conical Brine Tank Series (60L–1000L) is a robust, safe solution for brine storage, tailored to different capacity needs with specialized molding processes:


Dual Molding Technologies: 60L–300L models use blow molding, while 500L–1000L models adopt rotational molding—ensuring structural integrity for each size range.


Seamless, Safe Construction: The one-piece tank body has no adhesive joints, so it won’t crack or leach harmful substances. It’s lightweight yet durable: easy to transport, and resistant to shock and impact.


Specifications & Design: Available in sizes from 60L (φ380×750mm) to 1000L (φ1080×1460mm), all in white. The conical shape optimizes space utilization and material discharge.


Ideal for water treatment brine storage, this series balances safety, durability, and practicality across various operational scales.

【Product Overview】
The PE conical salt tank is a high-quality salt storage and dissolution container specially designed for the fully automatic soft water machine system. This product is made by rotating molding process using food-grade high-density polyethylene (HDPE/PE), featuring seamless, leak-proof, corrosion-resistant, and impact-resistant excellent characteristics. Its unique conical design not only has a beautiful appearance but also ensures that the salt blocks smoothly fall under the force of gravity, avoiding “bridging” or “suspended” problems, and guaranteeing the continuous and stable supply of salt solution (salt water) from the salt tank to the soft water machine for resin regeneration. It is a key supporting equipment for ensuring the long-term efficient and automatic operation of the soft water system.
【Product Features and Advantages】
Food-grade safe and durable: Made from food-grade HDPE/PE materials, ensuring the safety of the storage medium; the material is resistant to ultraviolet rays and acid-base corrosion, and can be used both indoors and outdoors, with a long service life.
One-piece molding, no leakage: Manufactured through advanced rotational molding technology, the tank body has no welds or seams, fundamentally eliminating the risk of leakage and achieving extremely high reliability.
Conical design, smooth salt discharge: The scientific conical bottom structure enables the salt blocks to naturally concentrate and dissolve at the center under the influence of gravity. This effectively solves the common “salt bridge” problem in square salt boxes, ensuring a continuous supply of salt solution.
Large capacity option, convenient and efficient: Available in a large capacity model with a capacity of up to 1000 liters. This is particularly suitable for commercial, industrial soft water systems or households in areas with high hardness, significantly extending the salt addition cycle and reducing maintenance frequency.
Lightweight and easy to install: Compared to traditional fiberglass salt tanks, the PE material is lighter in weight, making it easier to transport, handle and install on-site.
【Typical Application Scenarios】
Whole-house soft water system packages for homes, villas and apartment buildings.
Central soft water systems for commercial establishments such as hotels, schools, hospitals and beauty salons.
Soft water preparation systems for industries such as food and beverage processing, boiler heating, and laundry rooms.
Any automatic sodium ion exchange water softening device that requires a large, durable and maintenance-free salt tank.
