The WDR series is a horizontal electric boiler comprising electric heating steam boilers, atmospheric pressure hot water boilers, and pressure hot water boilers. Using electricity as the heating source, it produces no waste gas, residue, or effluent during operation, improving the working environment while complying with national environmental policies. Additional features include low noise, stable operation, easy handling, and high thermal efficiency.
The electric control cabinet and boiler body are separately designed to prevent heat-induced aging and extend service life. The boiler body is constructed from steel plate with X-ray-inspected automatic welds, ensuring quality and aesthetic appearance. The boiler automatically monitors and controls the circulating pump based on outlet water temperature to meet daily operational requirements.
FEATURE
- High-quality insulation materials: Low heat dissipation loss and reduced energy consumption.
- Progressive load design: Protects heating elements, minimizes impact on power grid, and extends service life.
- Integrated furnace and control: Achieves electromechanical integration and reduces space occupation.
- Ceramic electric heating tubes: Surface load several times lower than metal tubes, extending service life and achieving up to 99% thermal efficiency.
- Flange connection: Electric heating tubes and furnace body connected by flanges for easy disassembly, installation, and maintenance.
- Multiple operating time periods: Several periods can be set per day according to requirements.
- Automatic fault memory: Convenient for inspection and maintenance.
- Digital LCD controller: Fully graphical operation interface; users can directly view operating parameters.
