CYBERROW DX ENGINEERING MANUAL
MODEL NOMENCLATURE AND FEATURES
Direct expansion CyberRow systems provide efficient cooling through one of three different methods of heat
rejection. Remote aircooled (A) systems shall utilize an outdoorcondenserto reject heat, whilewater cooled (W)
and glycol cooled (G) systems shall utilize a brazed plate heat exchanger mounted insidethe CyberRow cabinet.
The STULZ E² controller allows for independent valve and fan control so the unit can adjust immediately, and
precisely, to varying heat loads and optimize energy efficiency.
Features
• Highest cooling capacities in the industry
• 12” and 24" cabinet widths
• 3 EC Fans: Independently and infinitely adjustable EC fans ensure maximum efficiency
• Used in containment, open architecture, and hot spot reduction applications
• Adapts to both high and low density IT environments
• Wide range of cooling capacities available
• 100% front and rear service access
• Adapts to all major manufacturers' racks and rack containment systems
• Seamless integration with all BMS platforms
• pLAN link to 8 units without a BMS
• High air flow with less noise
• Built in redundancy and capacity assist functions
• Top and bottom piping options
• Casters and Leveling Feet included
• Indoor use only
• Installation on raised and non-raised floors

MODEL NOMENCLATURE SPECIFICATIONS
Air Cooled Remote Evaporator
(Models CRS - _ _ _ - AR)
The floor mounted precision air conditioner system
shall be a split air cooled evaporator with remote air
cooled condenser. The evaporator section shall house,
at a minimum, the evaporator coil, expansion valve,
compressor, evaporator blower/motor and associated
electrical and refrigeration components.
DX Water Cooled
(Models CRS - _ _ _-W)
The floor mounted precision air conditioner system shall
be self-contained to include an integral water cooled,
plate-fin condenser with factory installed head pressure
water regulating control valve(s). Condenser (source) water
shall be provided by a cooling tower or some other remote
water source.
Head Pressure Control
Head pressure shall be automatically controlled by factory
installed 2-way, or 3-way water regulating valves rated for
600 psig w.w.p.
DX Glycol Cooled
(Models CRS - _ _ _ - G)
The floor mounted precision air conditioner system shall
be self-contained to include an integral glycol cooled,
plate-fin condenser with factory installed head pressure
glycol regulating control valve. Condenser (source) glycol
solution shall be provided via a STULZ model GPS - _ -
_ remote glycol pump package and F _ S -_ dry cooler
system.
Glycol Regulating Valve
Head pressure shall be automatically controlled by factory
installed 2-way, or 3-way, water regulating valve rated for
600 psig w.w.p.

CYBERROW DX ENGINEERING MANUAL
Open aisle configuration organizes racks in a single row orin
hot and cold aisle rows, but without containment. The STULZ
CyberRow draws hot airfrom the external environment or hot
aisle, removes the heat, and supplies cooled airto thefront of
IT equipment in the cold aisle.
Hot aisle containment captures the hot exhaust air from
IT equipment and prevents from mixing with cool air. The
front of IT equipment is accessed in the external cold aisle.
The STULZ CyberRow draws the contained hot air from the
hot aisle, removes the heat, and supplies cooled air into the
external cold aisle.
Cold aisle containment captures cooled air from the STULZ
CyberRow and prevents it from mixing with hot air. The front
of IT equipment is accessed in the contained cold aisle. The
Stulz CyberRow draws hot air from the external environment,
removes the heat, and supplies cooled air back into the
contained cold aisle.
