Industry Background

In modern industrial systems, water treatment equipment and chemical dosing units, space efficiency and system integration have become key design priorities. Traditional cylindrical tanks are structurally reliable, but they often leave unused space during installation, especially in compact systems.

Rectangular plastic tanks provide a more efficient solution by fitting tightly into available space. Their geometry allows better alignment with surrounding equipment, making them ideal for integrated and modular systems. This is one of the main reasons why the K50L–K2000L range is widely used in industrial applications.

Core Advantage

These tanks are manufactured using LLDPE material through a rotational molding process, creating a seamless one-piece structure.

The absence of welding joints significantly reduces the risk of leakage.

Uniform wall thickness improves structural strength and durability.

Smooth internal corners reduce stress concentration and enhance long-term performance.

Compared with assembled or welded tanks, rotomolded tanks offer higher reliability in continuous operation environments.

Capacity Selection

Selecting the correct capacity is essential for efficient system operation.

Tanks from 50L to 200L are suitable for laboratory use and small dosing systems.

Models from 300L to 800L are commonly used in standard water treatment and industrial processes.

Larger tanks from 1000L to 2000L are ideal for centralized storage and high-capacity systems.

Proper capacity selection helps reduce refill frequency and improve operational efficiency.

Application 1 Dosing Systems and Water Treatment

Rectangular tanks are widely used in chemical dosing systems, especially for PAC and PAM applications.

Their shape allows easy installation of mixers, pumps and piping systems.

LLDPE material provides excellent resistance to common chemicals.

The stable structure ensures reliable long-term operation.

Application 2 Industrial System Integration

In industrial equipment design, efficient layout is critical.

Rectangular tanks can be installed directly against walls or inside equipment frames.

They support modular design and reduce overall system footprint.

This makes them highly suitable for automated and integrated systems.

Application 3 Chemical Storage

In chemical storage applications, safety and durability are essential.

Tanks must withstand liquid pressure, environmental exposure and long-term use.

The rotomolded structure provides uniform strength and reduces risk of failure.

LLDPE material ensures compatibility with a wide range of chemicals.

Structural Design Considerations

Key design factors include

Uniform wall thickness to prevent weak areas

Rounded internal corners to reduce stress concentration

Reinforced structure for improved load capacity

These features ensure long-term stability and performance.

Installation and Compatibility

Rectangular tanks offer clear advantages during installation

Flat surfaces allow easy positioning and support

They can be integrated into system frames without additional modification

Customizable inlet and outlet positions improve system compatibility

Proper planning of dimensions and connections simplifies installation.

Conclusion

Selecting rectangular plastic tanks requires a balanced approach

Capacity must match system demand

Dimensions must fit available space

Material must meet chemical requirements

Structure must ensure long-term stability

With proper selection, these tanks provide an efficient, reliable and space-saving solution for industrial and chemical applications.
