The ICI CALDAIE medium/high pressure hot water boiler model ASX is a fully packaged unit,complete with accessories for easy installation. It features a large volume flame reversal furnace with low heat release characteristics. The larger sizes of boiler incorporate a corrugated furnace, and this feature together, with the generously proportioned furnace in terms of length and diameter, ensures an even distribution of heat within the combustion chamber guaranteeing perfect combustion with both oil and gas firing. Such furnace geometry ensures that overheating of the tubes and tube plates is avoided and the longevity of the boiler is assured.

 

High efficiency guaranteed with every fuel medium/high pressure hot water boiler up to 12 bar.

High efficiency is essential: ASX guarantees it withOperating Efficiency

The ASX Hot Water boiler guarantees a maximum net working efficiency up to 92% at both high and low thermal load demands. This is mainly due to the generously sized internal transfer surface and the 80mm thick mineral wool lagging. The boiler shell is clad externally by aluminium sheet panels. Special attention having been paid to the elimination of heat bridges across the entire surface of these panels, the upper level walkway and the upper part of the piping panel.

Maintenance and Cleaning

The internal parts and accessories that make up the boiler, are within easy reach to facilitate cleaning, maintenance and inspection to ensure the safety and long life of the boiler.
