Overview

MISSION CRITICAL COOLING

gForce by Data Aire are efficient and economical while complying with strict
environmental requirements. Incorporating backward curved plenum fans with
electronically commutated (EC) motors, these units supply radially dispersed cooling
air at lower speeds allowing for more uniform static pressure across the room. These
fans provide more net cooling from the computer room air conditioning (CRAC) system.
DC motors are more energy efficient, providing an on-going savings year after year.
Each unit is factory run tested and put through a vigorous quality control procedure.

IMPROVED PERFORMANCE AND REDUCED MAINTENANCE

Backward curved fans discharge air radially, allowing for uniform static pressure across
the raised floor. Traditional forward curved fans prohibit optimal airflow through the
raised floor close to the CRAC. One of the key features of backward curved fans,
commonly referred to as plug fans, is that the motor and fan are integrated into a
single unit, and includes a separate speed controller. This eliminates the need for
monthly maintenance, belt replacement and all belt dust.

IMPROVED AIRFLOW DESIGN

The increased capacity of the gForce internal cabinet allows for less restrictive airflow.
When additional options are added to smaller cabinets, the static pressure within
the unit increases, making airflow more difficult. The advanced design of the bigger
interior and the product’s quality construction ensures the highest level of efficiency in
a precision air system.

DATA AIRE DELIVERS

Standard lead time for a standard unit is 30 days from date of order. With an optional
premium “quick ship” units can be expedited to ship in as little as one week. All units
are built to your specific order and specification. Not only does Data Aire deliver
standard products in short lead times, our consultative process helps you meet your
specific requirements.

 Design Features

DESIGN
gForce CW units feature a specially designed compact tubular steel frame which allows for minimum space
requirement of air conditioning equipment in the controlled area. Although compact, all parts are easily accessible
providing excellent serviceability. The heart of the system is the Data Alarm Processor (dap4), a microprocessor
based controller. The dap4 not only controls and monitors temperature, humidity, airflow, and cleanliness, it provides
component runtimes, alarm history, and automatic self-test.

FRAME AND CABINET

The heliarc welded tubular steel frame provides for maximum strength and ease of access. Side and front doors
can be easily opened and removed with quarter-turn fasteners allowing full access to all unit components. All doors
include one inch thick, 1-1/2 pound density insulation for thermal performance, protection, and sound attenuation.

COIL SECTION
Designed for draw-through application, the computer-selected, rifle-tubbing dual circuited A-frame coil has an
interwoven surface that increases unit efficiency at low load conditions. Air is drawn through both circuits of the coil at
low velocity providing effective surface exposure with minimum turbulence. The coil sits in a stainless steel drain pan.

FAN SECTION
Backward curved plenum fans with electronically commutated motors are used to provide the most efficient fan/
motor combination available in the market today. Electronically commutated motors are DC motors connected to
standard AC power. DC motors are more efficient that AC motors and can be programmed to run at various speeds.
With the fan blades directly connected to the motor, there is no need for periodic maintenance. In the unlikely event
of a fan failure, replacement is simple; remove four bolts, disconnect the power and remove the fan. Reverse the
process for installation of a new fan.

ELECTRIC REHEAT
Low-watt density finned tubular sheathed elements provide ample capacity to maintain room dry bulb conditions
during a call for dehumidification. Three stages of reheat are standard.

HUMIDIFICATION
gForce CW includes an electric steam generator humidifier with “quick change” disposable cylinders and an auto-
flush cycle. The steam generator humidifier, with its patented control system, optimizes cylinder life and energy
efficiency by concentrating incoming water to a predetermined conductivity much higher than that of any entering
water. The control system continuously monitors the conductivity in the cylinder through its electronics, which allows
water to be flushed as often as is necessary to maintain the capacity at this design conductivity. The high design
conductivity results in a minimum flushing of heated water, which saves energy. The humidifier is designed to allow all
units at any voltage to produce full rated steam output capacity at an optimum low water level based on this design
conductivity.

FILTER SECTION
Units are provided with 4 inch deep, MERV-8 pleated filters. The filter section is accessible from the top, front, or side
on downflow units, and the front and right hand side on upflow units.

System Control

SMART SYSTEM CONTROLS FOR MISSION CRITICAL ENVIRONMENTS

Incorporating advances based on years of control-logic experience, Data Aire system control products offer maximum
operational flexibility and growth potential. From a versatile microprocessor controller or a dependable relay
autochangeover unit, to accessories that help prevent hot spots in rack installations and compensate for short-term
power outages, Data Aire technology keeps you in command.
The gForce systems come equipped with dap4 touch for the dap4 control panel. dap4 supports the following
network protocols for integration with a Building Management System (BMS) for Computer Room Air Conditioning
(CRAC) system monitoring and control: Modbus RTU, TCP/IP, SNMP V1 or V2, BACnet IP or MS/TP and LonTalk SNVT.
Building Management System Interface: Unit(s) shall be furnished with an optional interface card to communicate
directly with the Building Automation System (BAS) through a RS-485, Ethernet or LonTalk port. All alarms, set points,
and operating parameters that are accessible from the unit mounted control panel shall also be made available
through the BAS.
