The Yongxing WDR series is a horizontal electric heating boiler designed specifically for industrial users seeking zero emissions, high automation, and large capacity. As a model of environmentally friendly thermal energy solutions, this series is widely used in hospitals, pharmaceuticals, food processing, and central heating systems—fields with stringent environmental requirements.
Its core advantages lie in its exceptional energy efficiency and stability: The WDR model adopts a shell-type horizontal structure with horizontally arranged internal electric heating tubes, providing a large steam space that ensures high steam dryness and stable pressure. Compared to vertical structures, its heat load distribution is more uniform, effectively extending the lifespan of the heating elements. Its thermal efficiency reaches up to 99%, achieving almost zero-loss energy conversion.
The system employs a separate electromechanical design, with an independently arranged control cabinet, avoiding heat-induced aging of electrical components and greatly improving equipment reliability. Combined with a PLC fully automatic intelligent control system, it can achieve tiered switching, effectively reducing the impact on the power grid. For customers with abundant power resources and large-scale steam demand, the Yongxing WDR boiler is an ideal choice for achieving low-carbon production and efficient energy supply.
The WDR series operates entirely on electricity, producing zero CO2, NOx, or SOx emissions. It is the ultimate "Green Solution" for regions with strict environmental regulations, eliminating the need for a chimney, fuel storage, or complex emission treatment systems.
By using high-quality immersion heating elements, energy is transferred directly into the water with almost zero loss. This ensures a thermal efficiency of up to 99%, significantly reducing energy waste and lowering operational costs compared to fuel-fired boilers.
Equipped with a PLC intelligent control system, the heating elements are engaged in sequential stages (step-loading). This prevents sudden power surges, protects your local electrical grid, and allows the boiler to automatically adjust its output based on real-time steam demand.
The horizontal structure provides a larger water surface area and an expansive steam space. This design ensures rapid steam-water separation, resulting in high-purity, dry steam that is essential for precision industries like pharmaceuticals, food processing, and sterilization.
Unlike compact models, the WDR features a separate electrical control cabinet. By isolating the sensitive electronic components from the heat of the boiler body, we significantly prevent thermal aging, reduce failure rates, and extend the lifespan of the control system.
We utilize premium seamless stainless steel or Incoloy heating tubes designed with a low surface heat load. This minimizes scale buildup and prevents overheating, ensuring the heating elements can withstand long-term, high-intensity industrial operations.
