Chapter 1 Description & Specications
1.1 General Description
Industrial Climate Engineering's (ICE) Environmental Control Units (ECU) 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 90,000 to 240,000 BTUH.
Resistance heating elements are available in various wattages.
Industrial Climate Engineering ECU's feature an exclusive electronic control board.
The control board consolidates several of the 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 to allow operation in cold temperatures
• Thermal expansion valve to improve both efciency and capacity over a wide range of ambient
temperatures
• Phase monitor to prevent operation if the unit is not properly phased
The ECU's 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.

The standard conguration is with the supply (conditioned) air at the top of the unit and the return air below it. In the reverse air ow conguration, the return
is at the top and the supply air below it.
3
Filter acces in the standard conguration is through the hinged, sheet metal panel on the exterior of the air conditioner. The "I" conguration allows access to
the lter from inside the building through the return air grille.
