Bryant’s Quantum Plus 591B with Puron® provides features
which cannot be matched by any other family of equipment. The
591B is a Quantum Plus air conditioning system utilizing Bry-
ant’s unique Puron refrigerant. The environmentally sound
refrigerant allows you to make a responsible decision in the pro-
tection of the earth’s ozone layer. Bryant’s Quantum Plus sys-
tems meet the Energy Star
®
guidelines for energy efficiency.
AVAILABLE OPTIONS
Puron® Environmentally Sound Refrigerant
—Is Bryant’s
unique refrigerant designed to help protect the environment.
Puron is an HFC refrigerant which does not contain chlorine that
can harm the ozone layer. The most important advantage of
Puron refrigerant is that it has not been banned in future air con-
ditioning systems as the traditional refrigerant R-22 has been.
Puron refrigerant is in service in thousands of systems proving
highly reliable, environmentally sound performance.
Heavy Duty Inlet Grille
—The DuraGuard™ coil protector,
made of a coated steel wire grid with vertical 3/8 in. spacing, is
designed to help protect the coil from inclement weather, van-
dalism, and incidental damage. It provides protection while not
restricting airflow and maintaining ease of coil inspection and
cleaning.
High Efficiency Performance
—Is delivered through a combina-
tion of features including Bryant’s Puron refrigerant, unique scroll
compressor, and advanced heat transfer surfaces. Efficiency rat-
ings are 11 to 12.5 SEER (Seasonal Energy Efficiency Ratio).
Sophisticated heat transfer surfaces utilized in Bryant’s 591B
design allow heat to easily be transferred to the outdoor air and
require less energy. The unique scroll compressor found in the
591B design performs quietly and adds to the overall efficiency of
the system. Finally, Bryant’s unique Puron refrigerant operates
more efficiently than ordinary R-22 refrigerant found in other sys-
tems. The efficiency levels provided by the 591B provide end
users with lower costs of operation than traditional air condition-
ing systems.
Assured Future Service
—By utilizing the environmentally
sound refrigerant, Puron®, 591B models will remain serviceable
well into the future. The Clean Air Act of 1990 has placed a cap
on production of most other refrigerants which has scheduled
reductions beginning in 2004. The resulting cap in production
ultimately results in a complete ban on many other refrigerants
in new equipment by the year 2010. These changes, required by
federal law, mean the supply of other refrigerants may be limited
in the near future making Puron the correct choice when consid-
ering long term serviceability.
Highly Reliable Performance
—Is delivered through the supe-
rior design of the system and componentry. The reliability of
the existing Quantum Plus models has been proven to provide
the lowest incidence of warranty service of any product in the
Bryant family in the past few years of service. Long term reli-
ability is assured through the use of both high and low pres-
sure switches which will not allow the system to operate in the
event of a significant change in operating pressure. In doing
this, the system is protected from damage if an unusual condi-
tion arises. Finally, Bryant includes a special liquid line filter
drier designed to trap moisture and contaminants which could
otherwise shorten the life of the system.
Application Versatility
—Bryant’s systems utilizing Puron
refrigerant have the same application guidelines as other sys-
tems. Applications which include long line sets (50 to 175 ft) or
applications which require the system to operate at low outdoor
temperatures (below 55°F) are approved under Bryant’s stan-
dard guidelines.
Bryant Coils and Fan Coils to Complete the System
—Bryant
specially designs both the outdoor product and indoor coil prod-
ucts to operate with assured reliability and performance. A wide
range of indoor coil options are listed in the ratings section of
this publication.
Special Protective Devices
—High and low pressure switches
and internal protection in the compressor including temperature
and current sensing overloads prevent operation under poten-
tially damaging circumstances. A special liquid line filter drier
designed to trap nearly 4 times the volume of contaminants of
standard driers provides superior protection from moisture
trapped in the system.
Electrical Range
—208/230v, single phase.
Wide Range of Sizes
—Available in seven sizes; 1-1/2, 2, 2-1/2,
3, 3-1/2, 4, and 5 tons.
Reliant Cabinet
—Galvanized steel is coated with powder paint
to provide a superior, long lasting appearance.
Totally Enclosed Fan Motor
—Protected from adverse weather
conditions.
Unit Design
—Enhanced copper and aluminum heat transfer
surfaces with vertical air discharge to direct air up and away
from the area.
External Service Valves
—Both service valves are back seating
type valves which are externally located. These unique valves
allow service technicians to evacuate or charge the system in
less time than standard service valves.
Easy Serviceability
—One panel provides access to electrical
controls and compressor. Removal of wire dome gives access
to fan motor and removal of the top gives access to the coil.
Agency Approvals
—591B models are listed with UL, c-UL,
ARI, CEC, and CSA-EEV. Special endorsements have also
been awarded these products by Energy Star® which recog-
nizes energy efficient products.
Limited Warranty
—A standard five year warranty on parts with a
10 year limited warranty on the compressor. Optional warranties
are available through your Bryant distributor.
