Efficiency
Low excess-air combustion reduces the heat lost warming surplus air, achieving high boiler efficiency.
NIPPON THERMOENER
60+ years of
Japanese engineering.
Guided by its philosophy of contributing to society through boilers, Nippon Thermoener (NTEC) manufactures once-through steam, hot-water, thermal-oil and biomass boilers, providing reliable thermal infrastructure for a wide range of industries.
Since 2023, NTEC has partnered with Chuang Ting subsidiary Green Water Precision Technology. Japanese equipment combines with over 30 years of Taiwanese engineering experience to provide local planning, installation, training, parts, repairs and maintenance.

Combustion control, vessel design and steam quality: one video on the core of NTEC's once-through boilers.
NTEC Boiler Features
Eight technologies for efficiency and steam quality.
Combustion, control, steam separation, low emissions and the boiler body: eight technologies at a glance.
99%
Steam dryness
Advanced combustion and pressure controls work with a baffle separator to maintain steam quality as loads change.
5:1
Wide turndown
Combustion capacity can be reduced to 20% of rated output, matching actual steam demand and reducing unnecessary starts and stops.
900mm
Slim footprint
The compact body reduces boiler-room space requirements and simplifies parallel installations and existing-site upgrades.
JET FILM
Film-jet combustion
NTEC combustion technology mixes fuel and air uniformly to balance efficiency with low emissions.
25ppm
Ultra-low NOx
Jet film combustion achieves low emissions of NOx at 25 ppm and CO at 30 ppm.
High Efficiency
Pressure-vessel design
An optimized rectangular combustion chamber, water tubes and downflow system combine high thermal efficiency with low pressure drop.
Made in Japan
Quality and Technology
Imported from Japan, with local selection, installation, repairs and maintenance by Chuang Ting in Taiwan.

Test conditions & technical notes
Actual evaporation is calculated using feedwater at 15°C and saturated steam at 0.49 MPa. Boiler efficiency uses the JIS B 8222-1993 heat-loss method.
Boiler efficiency tolerance is approximately ±1–2%; combustion capacity tolerance is approximately ±3.5%. Refer to official series catalogues and a Chuang Ting engineering assessment for fuel consumption, dimensions, economizer configuration and electrical requirements.
