Product features and advantages
Stable and mature
Adopting the advanced DC coil design technology of Heidelberg (Thermal Energy)Technology Company in Germany,this type of DC coil steam boiler is stable,energy-saving,and mature.It has   been used in Europe for more than 60 years.
Blowdown without boiler shutdown
With a unique direct-current coil design, the steam boiler requires no blowdown or shutdown during operation, making it more convenient and energy-efficient.
Absolutely safe with no hidden risks
Thanks to its small water capacity spiral coil design and the absence of a steam drum, the direct-current coil steam boiler is inherently explosion-proof. Since its introduction, there has never been a single explosion-related accident or casualty associated with this type of boiler.

Two placement forms
It can be flexibly placed vertically or horizontally according to the actual situation on site
Steam pressure
1.25 MPa-23.0MPa,with an overheating temperature of up to 650ºC Customizable according to requirements.
energy-saving
Thanks to its unique structural design, the direct-current coil steam boiler requires no preheating and can generate steam within 3-5 minutes after startup. It delivers steam on demand, ensuring immediate use with zero waste.
Advanced Services
The HD direct-current coil steam boiler adopts IoT (Internet of Things) technology and connects to the manufacturer's computer service center for 24/7 real-time monitoring. This enables proactive fault detection and prevention, ensuring safe and reliable operation throughout the year.

Reliability & Energy Efficiency
The boiler is equipped with a plunger pump or diaphragm pump, using fully proportional variable frequency control to deliver continuous feedwater. This maximizes continuity and energy efficiency, while avoiding frequent pump start-stop cycles. As a result, the quality of high-dryness steam is consistently ensured.
Modular boiler design for higher system efficiency
Direct-current coil steam boilers support a modular configuration (up to <200 tons of steam), allowing multiple units to operate in parallel. Thanks to their unique rapid start-up response, the number of operating units can be closely matched to real-time steam demand. This ensures that each boiler operates at peak efficiency, effectively avoiding the energy waste often seen with oversized single boilers running under low load. As a result, the overall thermal efficiency of the boiler system is significantly improved.
