High-performance, high-efficiency boilers that lead the way in energy saving and new technology.
Premium instant boiler
Tankless high-efficiency hot water boiler with fully proportional control for large-scale supply
A tankless hot water system that steadily supplies large volumes of hot water to large facilities.
- 70% less installation space · compared with conventional hot water systems
- Efficiency up to 93% · based on higher heating value
- NOx 20 ppm or less · ultra-low NOx premix burner across the full load range
Vacuum hot water boiler
Easy-to-use high-efficiency vacuum hot water boiler
The heating medium water is kept in a vacuum inside the boiler body, and its decompressed steam indirectly heats the heat exchanger to supply hygienic hot water.
- No license or inspection required · operates below atmospheric pressure, so anyone can run it
- NOx 40 ppm or less guaranteed · low NOx burner attached as default
- Helium leak test · 3-stage vacuum leak check
Pressure-free hot water boiler
Energy saving, low pollution non-pressure hot water boiler
A 3-pass inverted combustion boiler that runs at 95℃ or less in a pressure-free condition with the expansion tank directly attached. No license or inspection required.
- Rust-free hot water · indirectly heated stainless heat exchanger
- Up to 3 circuits · heating, hot water supply and circulation heating in one boiler
- Technical partnership with Naval, Italy · European technology and DongKwang know-how
Once-through steam boiler
High quality steam boiler with optimal design and strict quality control
A high-performance once-through steam boiler that generates dry steam right after ignition without preheating load loss, reducing fuel cost.
- 4~5 minutes after ignition · dry steam generated
- High-performance steam separator · high-quality dry steam even with sudden load changes
- One-touch automatic control · water supply, operation and burner stop
Flue and smoke tube boiler
Easy-to-use high-efficiency vacuum hot water boiler
A condensing boiler with an air pre-heater and economizer attached to the body, recovering the sensible heat of the exhaust gas and the latent heat of water vapor.
- Sensible and latent heat recovery · from the exhaust gas
- Integrated auxiliary facilities · blower, water pump, panel and automatic blow device
- No separate installation space · pre-heater and economizer attached directly
Electric steam boiler
Clean and eco-friendly electric steam boilers
An eco-friendly steam boiler with no exhaust gas and lower fuel cost than oil and gas boilers. It is ready to use once the electricity and water lines are connected.
- Special steam separator · produces high-quality steam
- Standard safety devices · overheating, low water level, overpressure and leakage protection
- Compact design · easy to install in a small space
D-Brain
Communication
It is a high-performance control device equipped with a microprocessor as well as an LCD display so that all operation and error conditions can be seen at a glance, ensuring your convenient use with the cutting-edge device possible of setting the operating status and conditions of the boiler, using serial communication between the computer and D-Brain.
