Specifications

6 InRow™ Direct Expansion Air Conditioners Technical Specifications 990-4617
Cabinet
The frame is constructed of 16 gauge formed steel for maximum strength. The cabinet is serviceable from the
front and rear. All exterior panels and corner posts on the frame are powder coated for durability and an
attractive finish. The front and rear exterior panels are constructed of 18 gauge perforated steel with 69.5%
open free area. All panels, which include a key latch for safety and security, allow easy access and removal.
Insulation (ACRD100 and ACRD200 series only) is 80.1 kg/m
3
(5 lb/ft
3
) density and complies with ASTM
E84 rating of 25/50.
Shutdown input/alarm output
The unit provides one field connection input for remote shutdown and one field connection alarm output.
Variable speed fans
Each unit is equipped with variable speed fans to allow for varying heat loads. In order to provide uniform
airflow over the cooling coil, the fans provide a draw-through air pattern. The ACRD100 and ACRD200 series
units are equipped with six direct drive fan modules. These fans are easily replaceable while the unit is in
operation. The ACRD500 and ACRP100 series is equipped with two backward inclined, direct drive fans.
Bay Kit-InRow DX/NetShelter SX
Baying kits made of 16 gauge steel enable baying the InRow DX to APC NetShelter enclosures.
Counterflow Cooling Coil/Condensate Pan
Designed for high sensible heat ratios, the coil is constructed with copper tubes, raised lance type aluminum
fins, and 18 gauge galvanized steel end plates. Coil headers are equipped with anti-drip shields in the event of
condensation. The condensate pan is thermal formed non-ferrous material, and is sloped for positive drainage
to provide higher indoor air quality.
Filters
Filtration of conditioned air is extremely vital to maintaining the clean, particle-free environment required by
electrical equipment. Filters are easily replaceable from the rear of the unit. The ACRD100 and 200 series
systems use greater-than 20% efficiency ASHRAE 52.1, 12.7 mm (1/2 in) washable filters that meet HF-1
standards for electronics (MERV 1 per ASHRAE 52.2). The ACRD500/ACRP100 series system uses a 30%
efficient, 102 mm (4 in), deep loading, pleated filter (MERV 8 per ASHRAE 52.2, EN779 G4).
Selectable top or bottom piping connections
The unit includes both top and bottom piping connections. All ACRD100 and ACRP500 series connections use
threaded ring seals for ease of installation and service. The ACRD200 series uses union connectors.
Network Management Card
The Network Management Card (NMC) allows communication with the Local Area Network (LAN). In
addition, the NMC permits multi-level access to monitoring, control, and event notification features over the
building network.
