TRIAD Boiler Systems has a manufacturing history of over 80 years.  TRIAD patented the original isolated, 
modular  boiler  system  concept.    Each  boiler  /  burner  package  has  been  specifically  matched  to  provide 
optimal performance.  The boilers, however, are only a part of the complete operating system.  They can only 
meet their ratings if the system is properly designed and if the boilers receive proper care. 
 
Two  major  things  must  be  focused  on  to  achieve  successful  implementation:  Proper  System  Design  and 
Proactive Preventive Maintenance.  While the TRIAD Boiler websit

www.triadboiler.com

 may address some 

issues,  a design engineer should be  involved.  This Operations and Maintenance  Manual addresses many 
issues regarding usage. 
 
It  is  important  that the  system  design matches  the performance of the  boiler.    A  compatible  design  that 
addresses combustion air, correct system sizing, fuel and water supply, and breeching is crucial, and should 
be the responsibility of the system design engineer who must also ensure local code compliance.  The boilers 
will meet their full potential when part of an appropriate system design. 
 
Efficient burner operation is highly dependent on proper adjustment, adequate combustion air, and correct 
breeching. Make sure you carefully read the burner Operating and Maintenance Manual. Incorrectly dealing 
with  these  issues  can  result  in,  among  other  things,  a  loss  of  efficiency,  higher  operating  costs,  sooting, 
frequent cleaning, and high carbon monoxide (CO) output. 
 
The successful, long-term operation of the boiler is dependent on the quality of its water.  Failure to provide 
suitable  water  will  result  in  corrosion  and  the  build-up  of  scale  and  mud  /  sludge  /  sediment  causing 
inefficient thermal transfer, an associated loss of efficiency, higher operating costs, and eventually lead to 
premature boiler failure. 
 
Being  cognizant  of  these  issues,  and  taking  proper  steps  when  required,  should  result  in  many  years  of 
successful boiler operation.

 

 

TRIUMPH SS HIGH EFFICIENCY BOILERS 

TRIAD is pleased to introduce a new line of High Efficiency boilers, the TRIUMPH SS series.  This product line 
is  designed  with  a  large  horizontal  combustion  chamber  matched  with  a  specially  engineered  vertical 
condensing  section  in  stainless  steel  AISI  316  Ti.  These  elements  are  immersed  in  water  contained  in  a 
horizontal boiler drum with a vertical column to which the system inlet and outlet connections are fitted. All 
the burners, controls, and pumps are all first quality name-brand OEM components.   
 
These boilers reach very high efficiency levels as the flue gases not only are released at a temperature little 
higher than that of the system return water, but also a large part of the water vapor contained in the flue 
gases is condensed, recovering the latent heat of condensation. 
 
Because the flame path is designed to go through the combustion chamber without inversion, the formation 
of Nitrogen Oxides (NOx) is limited as much as possible. This is because NOx typically forms when the flame 
remains at high temperature in the combustion chamber for long periods.
