Frequently Asked Questions
Q1: Can this system handle concentrated hydrochloric acid (e.g., 32% HCl)?
A: Yes, our dosing system is designed with corrosion-resistant materials such as PVDF and PTFE, which can safely handle concentrated HCl up to 37% at ambient temperature. For higher concentrations or temperatures, please consult our engineering team for material selection.
Q2: What control interfaces are available?
A: We offer a touch-screen HMI with PLC as standard. It can communicate via 4-20mA, Modbus RTU/TCP, Profibus, or Ethernet/IP for integration with your existing SCADA system. Remote monitoring via mobile app is also available as an option.
Q3: How long is the delivery time?
A: Standard models can be shipped within 15-20 working days after order confirmation. Customized systems typically require 25-35 working days, depending on complexity. We operate from Tianjin port with fast shipping options.
Q4: Do you provide installation and commissioning service?
A: Yes, we offer on-site installation and commissioning support for overseas clients upon request. Alternatively, we provide detailed manuals and video guidance for self-installation. Our technical team is available 24/7 for remote assistance.
Q5: Is the system compliant with international safety standards?
A: Our system is designed to meet quality management standards. Safety features include overpressure relief valves, leak detection sensors, and emergency stop buttons. Additional certifications like CE, ATEX, or UL can be arranged upon request for specific markets.
Q6: What is the warranty period?
A: We offer a standard 12-month warranty from the date of shipment. Extended warranties up to 36 months are available for an additional cost. Our warranty covers manufacturing defects in materials and workmanship.
Q7: Can I get a sample or trial unit?
A: Yes, we provide sample units for testing. Please contact our sales team to discuss your requirements. A deposit is required for custom samples, which is refundable upon bulk order placement.
Q8: How do you ensure the quality of the dosing system?
A: Each system undergoes a rigorous factory acceptance test (FAT) including pressure test, flow calibration, and full functional test before shipment. We also provide test reports and certificates of conformity.
