Condenser Section
Microchannel condenser coils are utilized on 3-12.5 Ton non-CDR units except for Heat Pump and 6.5, 8.5, and 12.5 ton
Reheat units. Heat pump and reheat units do not utilize microchannel condenser coils due to the increase on
condensation and drainage.
Microchannel coils offer many advantages over the traditional copper tube/aluminum fin design:
-Enhanced heat transfer for higher efficiency
-Low air pressure drop
-One piece, all aluminum construction minimizes galvanic corrosion (no copper to aluminum contact points)
-Zinc coating provides further protection
-Optional epoxy coating is available for harsh environments
-Maintenance benefits – microchannel coils are more durable than traditional tube/fin design and can handle
higher water pressures during cleaning. Coils are not nearly as deep as traditional tube/fin design (roughly one
inch deep), so debris clears easily during cleaning - restoring performance lost to dust, dirt, and pollen
accumulation.
-Lower refrigerant charge - microchannel coils require much less refrigerant.

Key Talking Points
−Highly customizable
−Longevity- Replacement opportunities- Same platform since 1996
−Unique to the industry with four independent cooling stages
−Staged (Up to 3), modulating, electric heat, hot water and steam heating options
−Hinged, tool-less access panels- Electrical, blower, filters, economizer/power exhaust sections
−Double-walled cabinet, Merv 7 and 14 air filters and painted or stainless steel condensate pan
options for superior IAQ.

tools.
Product in compliance with:
ASHRAE 90.1
CSA, U.L.1995
ETL

Construction Features
−Double Wall Construction - Each unit has both an exterior and an interior wall, which make for a
more rigid design with panels and doors that are solid, not flimsy. The unit features a fully
framed construction for even greater stability.
−Powder Paint - Industry leading 1000 salt spray hour paint keeps the unit in great condition for
years to come.
−Low Profile - Millennium units stand only 64” above their curb, minimizing potential aesthetic
conflicts.
−Extended flue connection - Each gas unit ships with a field mounted external flue. The flue lifts
all products of furnace combustion far above the unit - eliminating the possibility of corrosion in
the furnace heat exchanger from recirculating flue gases.
−Protective Covering - Special polyurethane sleeves which cover the distributor tubing keep
distributor tubes from contacting each other a causing a potential leak, something other
manufacturers neglect to provide.
Features and Benefits
−Constant, IntelliSpeed (Multi-Speed) and variable air volume options available. The onboard
Simplicity SE control allows multiple airflow configurations including factory and customer
installed variable frequency drive options.
−Simplicity Smart Equipment controls featuring onboard two line LCD display, navigational
joystick, standard supply, return and outdoor temperature sensors, Optional humidity and
enthalpy sensors. BACnet MSTP, N2 or ModBUS RTU communication protocols.
−Simplicity Smart Equipment controls can be controlled with a simple 4-stage cool, 3-stage heat
thermostat, stand-alone controlled by return air temperature or space sensor. BAS/EMS ready
with the field configurable BACnet MSTP, N2 or ModBUS RTU communication protocols.
−Efficient, Durable Scroll Compressors - The Millennium design uses industrial grade hermetic
scroll compressors for peak efficiency and low noise operation.
−Four compressors, four independent refrigerant circuits provide excellent capacity and
turndown control. Unlike many competitors with products having single refrigerant circuits
should there be an issue with a refrigerant circuit only 25% of the Millennium’s capacity is
impacted. Competitors may lose 100% capacity if a refrigerant issue occurs.

Vibration Isolation - The Millennium's
neoprene mounts are typically
sufficient for most applications but
when sound and vibration transmission
are a major concern, UPG 1"and 2"
isolation springs provides for even
greater air fan noise and vibration.
Flexible Motor Options- The
choices of 7.5, 10, 15, 20 and 25
horsepower supply fan motors
and 5, 7.5, 10 and 15 horsepower
power exhaust motors provide
flexibility and correct motor sizing
to assure proper airflow and
maximum energy savings.
Indoor Air Quality (IAQ) options-
Offered from simple 2” throw-away
air filters, to 6” 95% efficiency MERV
14 filters. A sloped drain pan is
available in aluminized/galvanized or
stainless steel material to eliminate
standing condensate and prevent
corrosion.
Tool-Less, Hinged Access - Access to
key unit components are easily
accessed through tool-less, hinged
access doors. Choose the factory
option of electrical, filter and blower
access or electrical, filter, blower, heat
section and exhaust/fresh air.

Outdoor Air Options- All fresh air
and exhaust hoods ship mounted
and ready. Aluminum mesh filters
and barometric relief dampers
included on all product ordered
with a motorized damper or
economizer.
Outdoor Air Options Continued-
Millennium packaged products
equipped with “Tilt-Out” side fresh
air hoods. Simply tilt the hoods out
and secure with two screws and
Done!
With the combination of both side
and end return hoods 100%
economizer operation is possible.
Many competitors cannot achieve
100% economizer operation due to
insufficient fresh air intake points.
Modulating, Multi-Staged Gas
Heat Options- Choose from single,
dual or three stage gas heat (3
stages 40 ton only). Modulating
gas heat is available on all 25-40
ton units that achieves up to an 8:1
turn-down.
Hot water, steam and electric heat
is also available.

Heavy Steel Lifting Lugs-
Positioned at each end and the
middle of the packaged units crane
lifts are quick and easily rigged and
prevent any possible unit damage
as long as proper rigging is done.
Some competitors punch holes in
the base rails for rigging, thus
providing the potential for unit and
unit base rail damage.
