InRow RP Technical Data Manual4
Standard Features
Insulated Cabinet
The frame is constructed of 1.5 mm
(16 gauge) formed steel for
maximum strength. 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.
Front and rear exterior panel are
constructed of 1.2 mm (18 gauge)
perforated steel with 69.5% open free
area. Insulation is 80.1 kg/m

density and complies with
ASTM E84 rating of 25/50. All
panels include a key latch for safety
and security for easy access and
removal.
Variable Speed Fans
The InRow RP unit is equipped with
variable speed, electrically
commutated, 400 mm (15.8-in)
backward incline, direct drive fans.
The chilled water unit is equipped
with three fans while the air-cooled
unit has two. In order to provide
uniform airflow over the cooling coil,
the fans provide a draw-through air
pattern. Fans are easily serviced in
the field.
Shutdown Input/Alarm
Output
The unit provides one field
connection input for remote
shutdown and one field connection
alarm output.
Chilled Water Flow Meter
Internal piping of the unit includes a
flow meter wired into the
microprocessor controller to display
chilled water flow and determine
operating performance.
2-way/3-way Floating Point
Valve (CW Only)
A floating point valve is
microprocessor controlled to regulate
the amount of chilled water into the
cooling coil to maintain desired
conditions. The standard valve
pressure rating is 4136.8 kPa
(600 psig). The maximum operation
pressure of the unit is 2068.4 kPa
(300 psig). The valve is user
configurable to be two-way or three-
way.
Counterflow Cooling Coil/
Condensate Pan
Designed for high sensible heat
ratios, the coil is constructed with
copper tubes, raised lance type
aluminum fins, and 1.2 mm (18
gauge) galvanized steel end plates.
Coil headers are equipped with anti
drip shields in case of condensation.
Condensate pan is UL94 V-0 thermal
formed non-ferrous material sloped
for positive drainage for higher
indoor air quality.
Electric Reheat
Electric reheat elements are low watt
density, wired for three-phase and
loaded equally on all three phases,
and electrically and thermally
protected by both automatic and
manual reset thermal cut outs. Reheat
elements are stainless steel, fin
tubular construction.
30% ASHRAE 52.1 Filter
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, 100 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.

G4)
Pipe Adapters (CW only)
Standard pipe connections are
38.1 mm (1 1/2 in) NPSM
(manufactured in accordance with
ANSI B.1.20.1).
Pipe Adapters (Air-Cooled
only)
Standard pipe connections are
31.75 mm (1 1/4 in) 12 UNF female
Rotolock (manufactured in
accordance with ANSI B1.1). The
adapter converts the rotolock to a
sweat adapter.
Selectable Top or Bottom
Piping Connections
Unit includes both top and bottom
piping connections. Top piping
connects to internal stubs and routes
piping upward out of the unit.
Bottom piping connects to internal
stubs and routes piping downward
out of the unit. All connections
utilize unions or rotolok fittings for
ease of installation and service
