evaporative cooling. during periods when ambient temperatures or loads from the building
or process are relatively high, the Nexus™ Modular Hybrid Cooler operates with all spray
systems active across all modules. During off-design conditions, the eC Fan System will
automatically and intelligently reduce speed whenever possible. As the load is satisfied,
the fans and spray pumps will cycle off.
BaC’s exclusive iPilot™ Control System enables multiple modes of operation to tailor water and

hCore® Heat Transfer Technology
Using a highly corrosion-resistant stainless
steel alloy and greater heat transfer surface,
it provides unmatched thermal
performance, exceptional reliability, and long
life in an incredibly compact package.
EC Fan System
Simple design for lowest maintenance, easiest
access and maximum efficiency, this system
includes a direct-drive radial fan and a
variable-speed EC motor.
Modular Design
Its flexible, robust design is ideal for confined
layouts and indoor installations. The lightweight,
compact modules can easily be maneuvered with
a pallet jack and fit into most freight elevators.
DiamondClear® Design
This innovative design significantly cuts
maintenance costs. The spray water basin has
60% less spray water volume, has turbulent
spray water flow, and can be inspected while
in operation. The high-performance spray
resists clogging and delivers proper water
coverage for reduced scaling.

iPilot® Control System
Minimizes operating costs by effectively balancing
water and energy savings based on your needs
and preferences with three modes of operation:
ENERGY SAVER Maximizes energy savings though evaporative cooling
WATER SAVER Maximizes water savings through dry cooling
NEXUS Balances energy and water savings to fit your needs
UV System (Optional)
Optional UV system reduces bacterial growth
for best water quality. Factory installed UV lamp,
intensity sensors, and recirculating pump wired
into the iPilot® Control System.
• Non-combustible construction for local code compliance
• Intake and discharge sound attenuation to further reduce sound levels
• Tapered discharge hood to elevate air discharge, increase air discharge
speed, or reduce plan area for indoor ducting
• Positive closure dampers to reduce heat loss from heat pump loops
during winter months
• UV System reduces bacterial growth providing best water quality
enhancing health and safety
