3 pass condensing steel boiler with single pass combustion chamber and with low heat load, suitable for pressure jet burners. Combustion chamber and condensing section underneath both constructed in titanium stainless steel aISI 316 Ti.
The Codex has a very high efficiency (max 109%) for the particular shape of gas plates, which allows obtaining of high exchange surfaces and turbulence of gasses.
These boilers are fitted with double skin third pass gas tubes which the boiler to operate with a return water temperature of 35 °C. Owing to the low water temperature in the boiler and the particular shape of the flue gas passages inner surfaces, the flue gases exiting from the outlet of the boiler pass into a flue gas condenser installed downstream of the boiler, where the temperature of the gases drop below dew point.
The MONOLITE GT has a very high efficiency (max. 109%) which places it at the peak of the classification according to European standards (Output Directive 92/42/EEC). The AISI 316 Ti furnace and vertical flues are capable of resisting attacks from acidic condensation.
The boiler is already equipped with a fully modulating premix burner, thus ensuring the highest performance.
The MONOLITE JB has a very high efficiency (max. 109%) which places it at the peak of the classification according to European standards (Output Directive 92/42/EEC). The AISI 316 Ti furnace and vertical flues are capable of resisting attacks from acidic condensation.
The boiler may operate with any kind of pressure jet gas burners, always ensuring the highest performance.
Owing to its slim design, the STELT DUAL boiler can be installed in the most plant rooms, particularly where the access is a problem. High water content and the twin water return, allow an easy installation for every plant application.
New condensing technology can be used on the traditional heating circuits as well (radiators, heating fan coils, etc.) increasing the efficiency up to 107%.
STELT is a commercial hot water condensing boiler for single or modular use. Small dimensions, high water content and very high efficiency (up to 107%) are the main features of this boiler. STELT is an ICI CALDAIE patented condensing boiler that allows the new technology of condensing to be easily utilised on a new or existing heating circuit.
The furnace, the boiler shell and the horizontal flue sections are fully manufactured in titanium stainless steel AISI 316 Ti.
The VERO-NOx is a, pre-assembled ﬂoor standing, gas ﬁred high efﬁciency condensing boiler. It is a compact design with a small footprint lending itself to both single and multiple boiler installations.
The WALL series are hot water condensing boilers specially designed for modular use. Each module consists of a 125 or 150 kW boiler with single pass combustion chamber and condensing section underneath, both constructed from AISI 316 L anti-acid stainless steel. Combustion of each module is provided by a total premix burner.
Up to 4 modules can be joined together for a maximum output of 600 kW.
