De Dietrich DTG condensing boilers Floor Made in France, the smart choice in France in northern Germany, is the largest boiler manufacturers in France, one of the leading manufacturers of heating production technology on the European market, too. High efficiency ultra-energy cast silicon aluminum condensing technology integrated heat exchanger allows the best to play, annual thermal efficiency up to 110%. Flexible power adjustment range premix combustion engine with proportional control valve and variable speed fan, the boiler power adjustment range from 18% -100%. Casting furnace heat exchanger using aluminosilicate material in order to achieve the best use of the condensing effect De Dietrich cast aluminosilicate one heat furnace, using alloys of the condensation technology is the best play Al is a very good heat conductor: seven times stronger than steel. Silicon guarantee see strong corrosion resistance. Lightweight and durable alloy reduces the weight of the boiler and improve the life of the boiler. Special furnace design, maximizing increased heat transfer area, the condensed outstanding results, use efficiency can be up to 110%. Stainless steel wire mesh covering the fire tube gas burner air / gas ratio fixed proportion of premix burner with valve and variable speed fan, the boiler of the power adjustment range from 18% -100%. Low operating noise. Clean combustion to reduce emissions of air pollutants can be achieved: nitrogen oxides NOX <35mg / kWh, carbon monoxide CO <45 / kWh. Low start power burner adjustable wide power range, adjustable from 18% to 100%, can better adapt to the needs of the actual heat load and low noise in the boiler at 1m noise measurement is 48dB (A) De Dietrich company France and Germany Dietrich company was founded in 1684, which lasted more than ten years of research and development time to create a Sustainable Comfort heat energy saving systems. The company currently has seven factories, including four located in north-eastern France, one in northern Germany, two in the Netherlands. Located in the De Dietrich Niederbronn thermal technology company iron foundry is one of the world's most advanced iron foundry. In 1980 the company research and development of proprietary products: eutectic cast iron boiler, and soon became the highest example of casting metallurgy. Provide quality high-quality heating equipment annually to more than sixty countries around the world.
