The W(L)DR series of electric-heating boilers are vertical resistive-element-heating shell boilers,
mainly comprising a shell, boiler heads, an outer color-plate package layer and electric-heating tubes.
The boiler adopts stainless steel electric-heating tubes of 15-50KW/group, allowing the water to
be electrically neutral, achieving a safe use, and protecting the water from being contaminated.
The stainless-steel electric-heating tubes are connected with the boiler proper through flanges,
achieving an easy cleaning and replacement. The exterior of the boiler is packaged by a layer
of color plate, making the boiler be anti-rust and aesthetically appealing.
The heat-preservation structure adopts a layer of glass wool and a layer of aluminum silicate
fiber, greatly reducing the heat loss.
The boiler is noiseless and pollution-free, and the heat efficiency is greater than 97%.
This series adopts a fully-automatic control system, and possesses various protection
functions such as water-shortage protection, electric-leakage protection, phase-loss
protection, overload protection and overpressure protection, realizing a safe and reliable operation.
The installation period is short, enabling the boiler to be immediately put into use once the
valves & instruments, the water source, the power supply and the discharge pipeline are communicated
on the site.
