Product Introduction
The fully‑premixed low‑NOx cast‑aluminum condensing boiler adopts advanced condensing recovery and metal‑fiber combustion technology. Equipped with high‑grade international core parts and LCD touch‑screen PLC control, it delivers ultra‑high thermal efficiency, low‑emission combustion and flexible multi‑unit linkage. Compact‑sized and easy‑to‑install, it supports remote monitoring and multi‑zone control, ideal for commercial and industrial heating & hot‑water projects.
Core Advantages
- Small footprint & low installation cost: Compact lightweight structure; PVC flue pipe available for easy field setup. Built‑in multi‑layer gas & temperature safety protection.

- High efficiency & eco‑friendly: Cast‑aluminum heat exchanger plus metal‑fiber fully premixed burner. NOₓ<30ppm, saves over 15% energy, low flue‑gas temperature.

- Durable & low‑maintenance: International‑brand core components; heat exchanger service life over 20 years. Wide‑flow channel design, fewer wearing parts and variable‑frequency fan cut servicing cost.

- Smart flexible control: LCD touch‑screen PLC controller, supports remote monitoring, mobile & PC access, fault email alarm, multi‑zone management and max 16‑boiler cascade control.

- Complete service guarantee: Reliable pre‑sales technical support, full after‑sales service and product insurance for worry‑free operation.
