QILEE Chemical Dosing Systems Manufacturer

Product Overview

1) Product overview

Product Features

- QILEE’s Chemical Dosing Systems are packaged recirculating water dosing units (also offered as automatic nitrogen/chemical dosing systems) designed for industrial and commercial water treatment.

Product Value

- Typical basic spec (example model): metering pumps 7.6 LPH × 2, tanks 100 L × 2, recirculating capacity ~2,000 TPH, cabinet size ~1200 × 800 × 1600 mm. Multiple model variants are available with larger pumps, tanks and higher circulatory capacities.

Product Advantages

- Manufactured in Shanghai with export‑grade packing and a monthly supply capacity (standard models) of about 20 sets. Lead times typically range from 3–30 days depending on order size and season.

Application Scenarios

2) Product features

- Automatic, metered chemical dosing for scale inhibitors, corrosion inhibitors, biocides and other reagents.

- Online parameter monitoring options (pH, ORP, conductivity, residual chlorine, turbidity, corrosion rate, reagent concentration).

- Remote wireless transmission and real‑time status monitoring of online parameters and equipment operation.

- Uses selected internationally known instruments, metering pumps and valves for stable long‑term operation.

- Modular model range (multiple pump/tank/configuration options) to fit different flow and dosing requirements.

3) Product value

- Ensures accurate, reliable chemical feed that improves water quality control and reduces chemical waste and operating costs.

- Automation and remote monitoring reduce manual intervention, lower labor and human error risk, and enable faster response to process changes.

- Durable construction and quality components reduce downtime and maintenance costs over product lifetime.

- Scalable model options allow specification to the customer’s process, producing better performance and regulatory compliance in water treatment applications.

4) Product advantages

- High quality materials and strict factory testing for long‑lasting, stable performance and safety during delivery and operation.

- Adoption of well‑known international components to ensure reliability and serviceability.

- Wide model lineup (from small recirculating units to high‑capacity pump packages) to meet diverse industrial needs.

- Proven track record with large enterprise customers and long‑term cooperation with chemical suppliers.

- Export experience, reasonable lead times and convenient logistics from a Shanghai manufacturing base.

5) Application scenarios

- Open cooling water systems and closed chilled water systems in industrial facilities and large commercial buildings.

- Large water‑cooled central air‑conditioning systems and central plant operations.

- Industrial wastewater treatment plants and process water conditioning.

- Corrosion and scale control, biocide dosing, residual disinfectant control and reagent feed in manufacturing sites (including semiconductor and other large enterprises).

- Any process requiring automated, monitored chemical dosing and recirculation for large flow rates and continuous operation.
