QILEE Chemical Dosing Systems Chemical Dosing Systems Supply-1

Product Overview

- QILEE Chemical Dosing Systems are skid-mounted, integrated metering solutions designed for accurate, continuous dosing of paper-making chemicals.

- Systems combine metering pumps, on-line dilution/mixing, PLC control and monitoring on a single frame, with capacities customizable from 0.5 to 5,000 L/h.

- Standard construction uses corrosion‑resistant materials (316L, PTFE) and optional upgrades (Hastelloy, PFA) for aggressive chemistries.

Product Features

- PLC-based control with touch-screen HMI, dual operation modes (automatic closed‑loop linked to speed/flow and manual override).

- On-line dilution and mixing nozzle for uniform concentration and precision dosing.

- Comprehensive monitoring and alarm suite (liquid level, flow, pressure, pump overload) plus safety accessories (emergency stop, leakage protection).

- Modular skid layout for compact footprint and easy maintenance; standard metering pumps, filters, flowmeters and agitators.

- Customizable options: multi‑aid integration (up to 8), IoT remote monitoring, automatic replenishment, online concentration feedback and automatic cleaning.

Product Value

- Ensures consistent paper quality through stable, accurately controlled chemical dosing and real‑time adjustment to production load.

- Reduces chemical waste, operational downtime and manual workload via automated dilution, alarms and optional auto‑replenishment/cleaning.

- Improves plant safety and longevity by using corrosion‑resistant materials and built‑in protection features.

- Space- and labor-saving skid integration shortens installation and commissioning time.

Product Advantages

- Robust automation and flexible control modes enable closed‑loop integration with DCS and easy on-site adjustments.

- Durable, corrosion‑resistant construction minimizes maintenance and total cost of ownership.

- Broad customization (capacity, materials, control upgrades, environmental adaptations) fits diverse mill needs.

- Strong after‑sales support: 18‑month warranty, 24‑hour technical response and on-site commissioning assistance.

- Competitive pricing and export experience support rapid delivery and global deployment.

Application Scenarios

- Pulping: dosing cooking aids and bleaching aids.

- Wet‑end paper forming: dosing sizing agents, retention/drainage aids, reinforcing agents, bactericides and cleaners.

- Dry‑end/finishing: softeners, surface sizing agents, waterproofing and anti‑yellowing agents.

- Paper machine maintenance: routine bactericide dosing, cleaning cycles and online cleaning of lines/tanks.

- Can be adapted for high‑humidity, high‑temperature or cold environments and for multi‑chemical centralized dosing stations.
