Overview

Introduction

The APC AFX series precision air-conditioning system provides compact,

 

quiet, efficient, and reliable system solutions in the expanding precision air-

 

conditioning market. The AFX series is offered in a wide variety of

 

capacities, configurations, and air patterns within an extremely compact

 

cabinet size.

 

Precision environmental control requirements now reach far beyond the

 

confines of the traditional data center or computer room to encompass a

 

larger suite of applications, referred to as technology rooms.

 

Typical technology room applications included:

 

Computer rooms

 

Telecommunication facilities

 

Clean rooms

 

Power equipment

 

Medical equipment rooms

 

Archives

 

LAN environments

 

A worldwide network of APC representatives is fully qualified to provide

 

engineering, sales, installation and service for our products.

 

Our commitment to quality is demonstrated by the APC industry-leading

 

two-year parts warranty.

Capacity

Available are 6 through 28 nominal tons (20 kW–96 kW) in nine models and

 

3 cabinet designs.

Air pattern

Downflow units discharge air into the raised floor plenum eliminating the

 

need for air distributing ductwork. This enables the owner to locate the unit

 

where space is available or relocate the unit as the room changes or expands.

 

These units are suitable for areas with raised floors greater than 12" (305

 

mm) high. Air is drawn in through the top of the unit. Downflow units also

 

include a static regain duct which increases performance and efficiency while

 

reducing noise level.

 

Upflow units discharge air into either a plenum or ductwork. These units are

 

suitable for areas with raised floors less than 12" (300 mm) high. Air is drawn

 

in through the front on the standard design or optionally from the rear of the

 

unit.

 

Control

The microprocessor controller provides advanced integrated system

 

operation and management ensuring simple, reliable and precise temperature

 

and humidity control.
