Premium Instant Boiler's Best Technology for Hot Water
- It stably supplies large amounts of hot water to large hot water suppliers while satisfying the hot water load without a hot water tank. Satisfying all loads with full proportional control and the application of the country's first hot water logarithmic division system. The technology as a hot water tank system is the best in Korea, reducing the installation area by 70% compared to the existing hot water generation system and reducing maintenance costs by not installing hot water storage tanks. Unlicensed uninspected products in the form of indirect heating boilers can reduce additional costs such as customs and other drug injection costs. Our high-performance heat exchanger is designed for smooth hot water flow, so there is no scale deposition and foreign matter deposition, maintaining the initial efficiency of installation for more than 10 years.
-
Hot water supply system for no hot water tank
(Tankless system) -
Compared to the existing hot water system
70% less floor space -
Reduce incidental costs such as safe products and customs costs with no license and no inspection products
-
Through the simplification of auxiliary facilities
Reduce maintenance costs -
Korea's highest efficiency of 93%
(Based on total heat generation) -
Highly scale-resistant with
specially designed high-performance heat exchangers -
Fully proportional control operation
-
Average hot water temperature between 65℃ and 70℃ reduces the risk of infection by reducing the density of Legionella and reducing the possibility of contact.
PREMIX BURNER
- Premixed Combustion
- There is no need for a separate combustion space due to the surface combustion method.
- Fully proportional controlled operation (15:1 MAX)
- There is no explosion in the furnace compared to the forced mixing method in the pre-mixing method.
- Ultra-low NOX implementation at full load (nitrogen oxide of 20 ppm or less)

D-BRAIN (MODULAR SYSTEM)
-
Developed with 60 years of know-how in producing hot water boilers,
Korea's first hot water boiler system D-BRAIN large water control system contributes to energy saving by innovatively
controlling the number of boilers by temperature sensing the feed load flow rate and average flow rate.

The above specification table is indicated as follows.
- The fuel calorific value of fuel consumption was based on the following.
- Fuel: High calorific value_Low calorific value
- LNG : 11,000_10,000 kcal/N㎥
- Propane: 24,350_22,400 kcal/N㎥ (11,969_11,089 kcal/kg) - Design Flow Conditions for Heating and Hot Water Circulation: 333~343K{60~70℃}
- Design flow rate for hot water supply: 298 to 338K{25 to 65℃}, 278 to 338K{5 to 65℃}
- Maximum working pressure: 10-20 kgf/cm²
-
Rated heat output for heating and hot water use is for individual use and simultaneous use
In this case, the total is the boiler heat output. -
The instrument or instrument's measurement error contains the following allowable values:
- Boiler efficiency measurement error ±1% and fuel volume (heat input) measurement error ±1.5% - The boiler efficiency is based on the amount of heat generated (low heat generated).
- The above specification table is subject to change without notice.
- The logarithmic control system is optional. (3+ installations, up to 15 installations)
