Chapter 1 Description & Specications
1.1 General Description
Industrial Climate Engineering's (ICE) "CFA" and "CGA" Environmental Control Units are a series
of vertical wall-mounted air conditioning systems that provide heating, cooling, and ventilation for
electronic equipment shelters, process control centers, E-Houses, and other applications with high
internal heat gains. The series includes multiple sizes and nominal cooling capacities from 120,000 to
360,000 BTUH. Resistance heating elements are available in various wattages.
Industrial Climate Engineering models feature an exclusive electronic control board.
The control board consolidates several electrical components, improves the air conditioner’s reliability
and has LED’s to indicate operating status and fault conditions to assist the service technician. A complete
description of functions of the control board is in Section 1.6
Other standard components include:
• Hot gas by-pass valve provides for closer temperature control in mechanical cooling and protects
against coil freeze-upduring low load conditions.
• Thermal expansion valve to improve both efciency and capacity over a wide range of ambient
temperatures
• Phase monitor to prevent operation if the unit is not properly phased and high/low voltage
ICE CFA & CGA units are designed for easy installation and service. Major components are accessible
for service beneath external panels.
All units have internal disconnects. Depending upon state and local code requirements, this feature
may eliminate the need for an external breaker or disconnect.
