Hot water boilers ICI CALDAIE TNX, TNX EN, TNOX, REX, etc.

ICI Caldaie hot water boilers are gas–tube boilers made according to a three-way scheme or a two-way scheme with a reversible furnace. All boilers have a large water volume to ensure a low heat load, reduce consumption to maintain the boiler temperature and ensure a long service life. Boilers are designed for industrial applications and for large heating systems.

TNX

The heat generator with chimneys with three flue gas revolutions with a washed bottom and automatic operation is designed for burning liquid or gaseous fuel under pressure for large heating systems with a capacity of 2500 to 6000 kW and an operating temperature of 60 to 100 °C. Designed for a maximum safety temperature of 110 °C (modifications are available for pressures up to 10 bar).

• Design pressure: 6 bar.
• Useful power: 3000 ÷ 7000 kW.
• EFFICIENCY: 92.0%.
