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

Hot water boilers ICI CALDAIE 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 low heat load, lower flow rate to maintain boiler temperature and ensure a long service life. The boilers are designed for industrial applications and for large heating systems.
