Chemical Dosing Systems by QILEE

Product Overview

QILEE Chemical Dosing Systems are high-quality, factory-tested dosing units designed for automatic chemical addition in water circuits. Built from premium materials with advanced manufacturing, the systems integrate dosing tank, mixer, metering pump, PLC control, valves and piping on a single base platform to deliver a compact, ready-to-install solution. The product is internationally certified and developed to protect and optimize industrial circulating water and air-conditioning water systems.

Product Features

- Automatic, continuous and proportional dosing by monitoring makeup water volume, conductivity ratio or temperature differences.

- Programmable daily dosing times and PLC-based centralized control for integrated, hands-off operation.

- Modular, compact skid-mounted design that centralizes all components (dosing bucket, mixer, metering pump, valves) for simple installation and commissioning.

- Supports common corrosion and scale inhibitors (e.g., polyphosphates, zinc salts, polycarboxylates, phosphonates) and use of ferrous sulfate for protective film formation.

- Environmentally friendly and cost-effective operation; system quality checked before shipment and compliant with international standards.

Product Value

The dosing system preserves pipework and equipment by preventing scaling and corrosion, improving operational safety and thermal efficiency. Automated proportional dosing reduces chemical waste and manual intervention, lowering operating costs and labor. By optimizing chemical consumption (typical reductions of 20–30%), it delivers faster return on investment and supports more reliable, longer-lasting water systems.

Product Advantages

- Proven reduction in chemical consumption (around 20–30%) through proportional automated dosing.

- Turnkey, skid-mounted design enables fast deployment and simplified commissioning.

- PLC control and centralized installation provide reliable, repeatable dosing and easy operation.

- Manufactured to high standards with international certification and pre-shipment quality checks.

- Backed by QILEE’s 20 years of process design experience, global project footprint (40+ countries) and dedicated R&D and technical support for tailored solutions.

Application Scenarios

Ideal for water treatment in industrial circulating cooling systems, cooling towers and central air-conditioning circulating water. Suited for boiler feed and HVAC piping where corrosion or scaling risks exist. Applicable across industrial plants, large commercial buildings, power and process facilities that require controlled addition of corrosion inhibitors and scale inhibitors to protect heat exchangers, pipelines and system components.
