HIGH EFFICIENCY
CONDENSING BOILERS
Rounds Company carries High Efficiency Condensing Boilers manufactured
by Cleaver-Brooks and Fulton.
The Clear
Fire from Cleaver-Brooks is a revolutionary hot water boiler
design that is in-tune with the environment and today's market
needs.
The Pulse product
from Fulton has been greatly refined and is capable of very high
efficiency under condensing conditions. It is excellent for building
reheat, heat pump jobs and compensated hot water systems that will
run at low temperature. Refinements include much lower sound levels
and excellent reliability.

Cleaver-Brooks Clearfire
This state-of-the-art unit has been designed with today's demand for
high thermal efficiency, quick response and challenging systems dynamics
in mind. The Clearfire has a range of sizes to meet almost any commercial
applications, combines engineering expertise with ISO 9001 quality standards
to deliver a product unsurpassed in the industry when it comes to peak
performance and low environmental impact.

Fulton Pulse Hot
Water and Steam Boilers
These Pulse Combustion
low and high pressure steam boilers are the only pulse combustion steam
boilers available. The input ranges and sizes make them prime subjects
for single and modular installations for both new and retrofit projects.
The width is only 34". The special combustor design gives long lasting
heat exchanger life. The combustor travels the full interior length of
the pressure vessel. Attached is the exclusive Fulton "Thermalflex"
formed pipe system. Combined, this assumes maximum overall even heating.

Features
and Advantages
- No expensive
chimney or stack is required. Vents through the roof or sidewall.
- No boiler
room makeup air is required. Combustion takes place in a sealed
combustor.
- No moving
parts. Only a small assist fan needed for starting.
- A simple
spark plug is all that's required for ignition.
- Low NOx
emissions. Inherent with pulse combustion are low temperature
exhausts and low NOx emissions making clean natural gas fuel even
cleaner. Fulton's pulse units meet all new stringent government
emissions standards.
- Quieter
than most conventional power burners.
- Stand-by
losses are nearly nonexistent due to air metering valve.

 Fulton
VANTAGE
The new Fulton Vantage rovides maximum performance and an input of 3,000,000
Btu/hr, making it the perfect boiler for any large heating application.
The
VANTAGE is designed with a large condensing heating surface. The
result is a reliable
boiler which reaches maximum efficiencies possible for the corresponding
return water temperature.

Fulton PulsePak
A PulsePak boiler operates
with a standard efficiency of approximately 84-90%. For optimum performance
Fulton's PulsePak can be ordered with modulation which results in efficiencies
of up to 98%. Fulton Model PHW-1400 is supplied with modulation as standard
equipment. Unlike conventional power burners, pulse boilers are modulated
by using a standard butterfly valve in the gas line and a butterfly valve
in the exhaust line. The result is a boiler that offers 5:1 turndown for
precise load matching capability. Sound deadening features bring the DBA
to less than 70 on all PulsePak boilers - quieter than most other HVAC
equipment.
 |
Benefits
with Pulse
- Standby losses are
nearly zero.
- Small footprint allows
installation in multiple buildings or in isolated areas of large
plants.
- Fit through standard
door openings.
- No power burner combined
with the pulse design, results in the lowest maintenance requirements
in the industry.
- No primary/secondary
loop required to maintain minimum return water temperature.
- Pulse combustion produces
inherently lower NOx levels than conventional boilers.
- No minimum or maximum
flow requirements.
