||Eutectic Cast Iron Means Strength
De Dietrich R&D developed a new eutectic cast iron in 1980 and it quickly
became the highest reference in cast iron metallurgy.
The word “eutectic” means that the melting point temperature of the cast iron
is lower than the melting point temperature of all of the components included
in its manufacture.
In operation, eutectic means strength:
iron results in greater structural integrity
standard in resistance to corrosion allows no weak points or pitting corrosions
The ability to
withstand low water temperature input creates longer boiler life
Time and money
are saved through easy cleaning and maintenance
Flexible Cast Iron Creates Longer Operating Life:
Thanks to the most modern processes and the high quality of its eutectic cast
iron, De Dietrich manufactures the most flexible cast iron in the world. Its
modulus of elasticity is 30% greater than any other cast iron currently
line result of De Dietrich in depth experience is:
Savings in time,
money and fuel consumption
for equipment maintenance and replacement
Efficiency Greater Than 88% Saves Money:
Supported by powerful computers in state-of-the-art equipped laboratories, the
De Dietrich Research and Development Department designed an optimized cast iron
section that achieves full heat transfer through:
3 & 4 pass
fire chamber design
that permit greater heat transfer and combustion efficiencies greater than 88%
Fire box totally
surrounded by system water
Temperature Produces Extraordinary Annual Efficiency:
By using indoor/outdoor reset, De Dietrich boilers can modulate to lower
temperatures than all other cast iron boilers. The result: extraordinary annual
efficiency as well as greatly increased control and ease of installation.
Boiler temperatures can go down to 85° F for the GT 300 series and 105° F for
the GT 400 and GTE 500 series without damage to the castings. The design and
quality of the cast iron provide control and operating efficiency, thus
assuring lower operating costs and longer life. Low operating temperature
capabilities make the GT series ideal for water to air heat pump or 2 pipe
Insulation Minimizes Heat Loss:
In order to achieve its very high annual efficiency, De Dietrich boilers are
equipped with a minimum thickness of four inches of reinforced fiberglass wool
insulation around all combustion/furnace areas of the boiler.
Heat losses are therefore reduced to the minimum possible.
Low NOx Emissions
Consider the Environment:
The future demands careful energy management that protects our environment.
De Dietrich’s state-of-the-art design allows easy application of low NOx and CO
emission burners. This will become even more important as we enter the next
Up to 91 PSI Working Pressures Maximize Your Flexibility:
De Dietrich boilers meet ASME requirements and rate far above other industry
On special-order commercial and industrial boilers, the maximum working
pressures of our boilers can go to 60 PSI for the GT-200A series, up to 81 PSI
for the GT-300A series, up to 91 PSI for the GT-400A series and up to 83 PSI
for the GTE-500A series.
Your bottom line benefit: greater versatility and flexibility of application
for both hydronic heating and process systems.
and Cleaning Save Dollars:
De Dietrich boilers are supplied with high quality, removable, full-swing doors
that give access to all flue ways and combustion areas for easy maintenance and
cleaning without burner removal.
De Dietrich's boilers are also enhanced by removable cast iron turbulators
Nipple Assembly Ensures Perfect Fit:
Bi-Spherical push nipple assembly of De Dietrich boilers translate into longer
life, easier quicker assembly of sections, and higher operating pressure.
Machined to very close tolerances, their exceptionally tight fit produces both
safety and reliability.
Thermocord Prevents Flue Gas Leakage:
A siliconed thermocord is sandwiched between sections to provide the perfect
tightness necessary to prevent leakage of flue gas.
This careful attention to engineering increases safety and extends the perfect
operation of the boiler for many years.
High Performance Boilers SAVES
