990-4618C-001 InRow Chilled Water Air Conditioners Technical Specifications 9
30% ASHRAE 52.1 filter
(ACRC500/ACRP500 series only)
The filtration of conditioned air is extremely vital to maintaining
the clean, particle-free environment required by electrical
equipment. The system uses a 30% efficient, 102 mm (4 in), deep
loading, pleated filter. Deeper filters produce a lower pressure
drop, requiring less energy during normal operation. The filter is
moisture resistant up to a 100% relative humidity. Filters are easily
replaceable from the rear of the unit. (MERV 8 per ASHRAE 52.2,
EN779 G4)
Selectable top or bottom piping connections Note:Unit includes both top and bottom piping connections. Top
piping connects to internal piping connectors and routes piping
upward out of the unit. Bottom piping connects to internal piping
connectors and routes piping downward out of the unit. All connec-
tions are unions for ease of installation and service.
Note: Top piping for ACRC301S and ACRC301H is available as an
optional kit.
Dual float condensate management
(Does not include ACRC301H)
The factory-installed condensate pump is piped internally to the
condensate pan. Dual floats are included with the unit. One float is
used for condensate pump control, the other to generate condensate
pan overflow alarms. For technical specifications, see
“Performance Data—General” on page 61.
Network management Permits multi-level access to monitoring, control, and event
notification features over the user’s network.
Service notifications (ACRC301 series only) Several components within the unit will provide a warning that
service is needed. There are multiple faults that can be detected and
reported (see “Alarms” on page 15). Notification is also provided
when a service interval expires.
Bay kit InRow RC/NetShelter SX Joining kits made of 16 gauge metal enable joining of the cooling
system to NetShelter SX enclosures.
Remote temperature sensor To control the unit based on rack inlet temperature, one remote
sensor is provided with ACRC301S and ACRC301H units
(factory-wired) and three remote sensors are provided with
ACRC500/ACRP500 series units (field-wired).
4.3-in. touch screen
(ACRC301S and ACRC301H only)
High-definition screen displays more data. Provides easy-to-read
system status information.
Casters Allows for the unit to be moved easily.
Easy-access electrical box
(ACRC301S and ACRC301H only)
Slide-out electrical box enables maintenance without removing the
unit from the row.
Active Flow Controller Compatibility
(ACRC301S and ACRC301H only)
Monitors pressure inside and outside the contained aisle and
adjusts cooling unit fan speed to match the airflow with that of the
IT equipment.
