AIR FLOW

In the LEONARDO EVOLUTION 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.

INTRODUCTION

Presentation of the system

The Leonardo Evolution™ 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 Leonardo Evolution series consists of 4 types of conditioners:
•  Direct expansion
•  Chilled water
•  Energy Saving
•  Twin-Cool

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.
