• Double-tank, double-valve water softening system is an upgraded system that has been widely used in the field of industrial water treatment in recent years.
• Compared with the traditional single-tank, single-valve system, it not only continues the basic functions of the traditional water softening system, but also achieves significant improvement in intelligent control, continuous operation and system redundancy.

Differences from Single-tank Water Softening Systems

• Common single-valve control system in a tank into the regeneration cycle, the need to temporarily stop the water supply, easy to affect the continuous production process.
• The two-tank, two-valve system is equipped with two completely independent control units and inlet and outlet lines. When either tank is regenerated, the other tank can be put into operation immediately, guaranteeing an uninterrupted water supply.
• Dual-valve operation is flexible according to the different water load automatically switching tanks, improve the overall system response capability and energy utilization.

Intelligent Operation Mechanism

The system supports a variety of operating logic, such as flow preset control, time period control, water habit learning. Some models are equipped with intelligent chips, which can monitor the hardness of incoming and outgoing water, water consumption curve and resin status in real time, and intelligently adjust the regeneration time and method in combination with the operation data, so as to avoid ineffective regeneration and save salt consumption and water consumption.

Technical Parameters

• Standard flow rate: 1~100 tons/hour
• Resin loading capacity: 80L~500L
• System design pressure: 0.25~0.6 MPa
• Average regeneration cycle: dynamically adjusted according to the set water quality and dosage.
• Low power consumption of electric control system, stable long-term operation.

Performance Advantages

• High stability: the controller and valve body are independent of each other, even if a single group failure does not affect the operation of the whole machine.
• Energy saving and consumption reduction: through reasonable scheduling of regeneration frequency, significantly reduce operating costs.
• Convenient operation and maintenance: modular design facilitates the replacement of resin, maintenance of valve body and updating of electronic control.
• Intelligent management: adapted to the industrial Internet of Things environment, to realize the centralization and visualization of water data.

Reasons for Use in Water Softening Systems

1. Prevent Scaling and Corrosion

In central air-conditioning and centralized heating systems, especially those that circulate through water (e.g., hot water boilers, cooling towers, etc.), hardness ions (calcium, magnesium, etc.) in the water tend to react with other components in the water to form scale. Scale will accumulate in pipes, radiators, heat exchangers and boilers, reducing heat exchange efficiency and leading to premature wear and tear, corrosion and even damage to equipment.

Removing hardness ions through a water softening system avoids scale formation and ensures the thermal efficiency of the water system and the normal operation of the equipment. Softened water can also avoid corrosion of metal equipment (such as boilers, pipelines), to extend the service life of the equipment.

2. Improve Heat Exchange Efficiency

The accumulation of scale will reduce the heat exchange efficiency and increase operating costs.

The use of softened water can maintain high fluidity and low resistance of water in heat exchangers, boilers and air conditioning systems, reducing energy waste and equipment loss.

3. Reduced Maintenance Costs

Softened water reduces scaling and corrosion problems, thereby reducing the frequency of equipment maintenance and associated costs.

4. Provide a Better Comfort Experience

The efficiency of the hot water system has a direct impact on indoor temperature stability and comfort. Water softening improves the system's responsiveness and makes it easier to control indoor temperatures.
