FAQ

1. What fuels are compatible with your boilers?
Our boilers support Natural Gas (NG), LPG, Diesel, and Heavy Oil. We also offer Dual-Fuel burners to help you switch sources based on local fuel costs.
2. What are the benefits of the corrugated furnace?
The large-diameter corrugated furnace and spiral tubes increase the heat exchange area and allow for free thermal expansion, achieving over 95% thermal efficiency.
3. Which brands of components do you use?
We use world-class components: Baltur, Riello, or Elco for burners (Italy), and Siemens or Schneider for PLC control systems, ensuring global reliability.
4. What safety features does the control cabinet have?
The PLC touchscreen provides 24/7 monitoring with auto-alarms and interlock protection for water levels, pressure, flame-out, and exhaust temperatures.
5. Is customization available for voltage and pressure?
Yes. We customize industrial voltage/frequency (e.g., 220V-440V, 50/60Hz) and working pressure (up to 2.5 MPa or higher) to meet your local standards.
6. How do you provide international after-sales support?
We provide complete video installation guides, remote video technical support, and a free package of spare parts for 1-2 years of operation.
7. Why choose a Three-Pass Fire Tube structure?
The "Wet-back Three-pass" design maximizes heat transfer and minimizes footprint. It offers lower maintenance costs and a failure rate below 0.1%.
8. What is the required gas inlet pressure?
Requirements vary by capacity: 8-15 kPa for 1-2 ton/h boilers, and 20-50 kPa for 4 ton/h+ units. We provide technical drawings for your site preparation.
