Condenser
• All units feature dual refrigeration circuit design with fully
interlaced evaporator circuits for redundancy and efficient
part load control
• A minimum of four stages of compressor capacity control
and optional hot gas bypass (on one or both circuits)
provides for stable discharge temperature and humidity
control
Fully Modulating Hot Gas Reheat with Two
Point Dehumidification Control
Hot refrigerant gas leaving the compressor can be directed to
a separate coil to reheat the cold, dehumidified air leaving the
cooling coil. This reheat costs no energy and is an excellent
way to precisely control and optimize dehumidification.
To provide optimized dehumidification control the Rebel
Applied dehumidification sequence controls the compressors
capacity by using direct feedback of the temperature leaving
the evaporator coil. This temperature is at a saturated coil
condition and is effectively the dewpoint that is being supplied
to the space. Directly controlling dewpoint provides users
with the flexibility to commission the equipment to provide
the dehumidification each application requires; No more, no
less. The fully modulating hot gas reheat coil is controlled
independent of the compressors to maintain constant supply
air temperatures which is critical to prevent over-cooling and
poor space control during dehumidification operation.
Energy Efficiency
• Industry leading energy efficiency customizable for any
application
• Select between two coil areas with 4 or 6 rows to optimize
energy efficiency to maximize Rebates
• Select between Daikin Fantrol, staged control, or
Speetrol, modulating condenser fan, control to meet
customer efficiency needs.

Minimums
Quiet Condensing Operation
Specially engineered quiet condenser design to reduce
radiated noise by an average of 10 dBA or more compared to
standard units.
Low Ambient Operation
Minimum Operating Ambient down to 50°F Mechanical Cooling
is included as standard. Optional fully modulating Low ambient
head pressure control allows mechanical cooling down to -10°F
ambient conditions.
Enhanced Serviceability
Optional Compressor Isolation Valves, Replacable Core Filter
Driers, and Refrigeration Monitoring sensors enhance the
servicability and longevity of rooftop systems.
