98%+ Boiler Thermal Efficiency

Direct electric heating has zero stack losses and converts nearly all input energy into steam. With PID control, energy is saved during variable-load periods by reducing steam production to match and maintain the required steam output. This results in lower costs for continuous-duty applications.

Zero On-Site Emission & NOx

All combustion pollutants are eliminated. No flue gas, particulate matter, NOx, or SOx is generated. This helps the facility meet environmental requirements, supports the facility's net-zero goal, and qualifies for the IRA clean energy tax credit.

Electrical Control Cabinet Separate Design

The control PLC cabinet is physically separated from the boiler for safe electrical isolation, maintenance, and troubleshooting. This design ensures full operational autonomy (automatic start, heater control, alarms, and shutdown).

Horizontal Electric Steam Boiler Layout

The horizontal configuration enables consistent water-level management and even heat distribution across the electric stainless steel heating tubes. A furnace arrangement optimized for space allows the furnace to maintain maximum heat-transfer surface area while keeping the boiler room footprint to a minimum, making installations more convenient.

Stainless Steel Heating Elements (20,000h Life)

Electric heating tubes are made of premium stainless steel with surface load optimization and a 20,000 service life. Durable industrial-duty cycles are supported by reinforced welded industrial-duty cycles with rated flange connections and ceramic insulation.

ASME / CE / CCC Multi-Certification

Constructed to the guidelines of the ASME Boiler & Pressure vessel code (and CE marking & CCC certification pathways). These Structured ISO 9001 (Quality Management System) procedures govern each process, ranging from the choice of raw materials to final Hydrostatic testing and commissioning documentation.

Boiler Accessories

Электрический паровой котел серии WDR — Standard Accessories & Components

All the WDR Series electric steam boilers come with the appropriate accessories that are designed for safety, efficiency, and long service life. Each component is chosen to complement the PLC control system and the horizontal design of the boiler.

WDR Series Electric Steam Boiler PLC Control Cabinet with LCD Display

Электрический шкаф управления

Benefit of safety and maintenance is accrued from separating the PLC cabinet from the boiler body. It displays real-time boiler status on an LCD touchscreen interface, which includes steam pressure, water level, heating element status, and fault alarms. Start-up sequencing, boiler group modulation, and multi-layer safety interlocks are some of the facilities the fully automatic system provides in protecting against dry firing and overpressure.

Centrifugal Feed Water Pump for WDR Electric Steam Boiler

Насос Кормовой Воды

The centrifugal feeding water pump ensures the correct water level inside the boiler drum by being operated automatically. Controlled by the PLC system and water-level sensors, the pump automatically starts and stops to reflect the real-time demand and hence prevent under- or over-watering. Sizing of the pump to match the boiler's rated evaporation capacity ensures efficient water supply to the boiler under conditions of continuous or transient operating loads.

Spring-Loaded Safety Valve for WDR Series Electric Steam Boiler Overpressure Protection

Предохранительный клапан

The crucial overpressure protection device on every steam boiler is the spring-loaded safety valve which is factory-set for the release of excess steam only if internal pressures exceed the rated working limit. As a result, dangerous pressure build-up and probable vessel failure are averted. In conclusion, all WDRs are equipped with a safety valve meeting ASME and the national pressure vessel standard, making export market compliance inevitable.

Steam Distribution Header Manifold for WDR Electric Boiler System

Steam Distribution Header

The steam manifold collects the steam after the boiler and output and evenly distributes it to various processing lines or equipment by branch outlet nozzles. It dampens the pressure fluctuations, provides extra moisture separation for better steam quality, and allows the isolation of particular processing lines for maintenance without any shutdown of the total system. Steel headers are fabricated with welded construction.
