Features and Benefits
LOW OWNERSHIP COST
Lower Installation Cost
• Single point power connections.
• Single condenser water inlet and outlet connections. Factory installed internal piping.
• Comprehensive factory testing of refrigerant, condenser water piping, supply fan,
and control system.
• Factory installed internal condensate drain connection.
• Compact design allows smaller mechanical equipment room.
• Optional low service clearance units allow installation in even smaller mechanical
equipment rooms.
•
Optional multiple piece shipment allows installation in tight spaces. No field refrig
-
erant or water piping is required.
• Condenser water piping connections from the top of the unit minimizes piping in
mechanical equipment room.
LOWER OPERATING COST
Efficient Operation
•
Plenum fan with backward inclined airfoil blades provides required airflow at a low
-
er energy consumption compared to the most competitive units.
•
All scroll compressors combined with highly efficient condenser and evaporator coil
design provides efficient cooling, lowering energy consumption.
• Water economizer and air economizer options provide free cooling to reduce power
consumption.
•
Partial occupancy on any floor reduces power consumption, due to multiple com
-
pressor operation and optional variable frequency drive (VFD) to match capacity to
the load.
•
After hours operation on any floor only requires unit on that floor with partial op
-
eration of cooling tower and pumps. This saves significant amount of energy over
chilled water systems.
•
Variable condenser water flow option, with internal actuated valve(s), prevents flow
through units not requiring cooling, saving pump energy.
• Evaporator coil circuiting supports low leaving air temperature designs to reduce
design air flow and reduce fan operating energy.
•
High efficiency evaporator coil available for lower air flow, low leaving air tempera
-
ture applications.
