INTRODUCTION

Presentation of the system

The Mercury precision air conditioners are designed for environments which are characterised by the presence of highly
technologically advanced equipment: telecomms and internet centres, data processing rooms and any type of environment
which is characterized by high concentrations of power.
The Mercury series consists of 2 types of conditioners:
• Direct expansion
• Chilled water
AIR FLOW
In the MERCURY conditioners, the air can flow upwards or downwards (UPFLOW / DOWNFLOW).
UPFLOW
Upflow units (with upwards air discharge) are designed to distribute the air through a system of ducts or by means of a
false ceiling. Air intake is usually through the front of the unit, but versions are also available with air intake through the
rear or the base of the unit.
DOWNFLOW
Downflow units (with downwards air discharge) handle large volumes of air which are distributed uniformly into the
environment by means of a void under a raised access floor. The air enters the unit directly from the environment, or
through a ventilated or false ceiling.
