Technical information manual <strong>UTA</strong>-ECHOS<br />
REF. <strong>UTA</strong>-ECHOS-/<strong>UTA</strong>_ECHOS_2011.DOC<br />
Units for applications of residential and commercial <strong>type</strong>, characterised by reduced dimensions and easy installation equal to a<br />
valve convector. Due to their reduced dimensions they are particularly indicated for installations in false ceiling with ducting or air<br />
emission directly in rooms.<br />
The air treating units are available in the following constructive versions:<br />
• <strong>UTA</strong> ECHOS direct expansion unit<br />
• <strong>UTA</strong>H ECHOS heat pump unit<br />
The <strong>UTA</strong>-<strong>UTA</strong>H ECHOS versions are complete with gas load inlet, thermostatic valve, inlet plug connection attachments with<br />
precarious refrigeration tap . The installation is made easier by the possibility to have (upon request) both the connections on the<br />
right side and the fan air flow downwards or upwards. The <strong>UTA</strong>-<strong>UTA</strong>H ECHOS versions are coupled with motocondensing unit<br />
functioning with R410A chiller. (Epsilon Echos /LE, Epsilon Echos /LE /HP, Mu Echos /LE, Mu Echos /LE/HP; coupling with Epsilon<br />
Echos /LE, /LE /HP is defined SPLIT SYSTEM ECHOS).<br />
TECHNICAL FEATURES<br />
<strong>UTA</strong> ECHOS - <strong>UTA</strong>H ECHOSl unit<br />
STRUCTURE<br />
In models 8-18, the structure is made up in galvanised sheet with internal thermo acoustical coating in flexible polyurethane with<br />
open cells (density 30 kg/m3), flame retardant in class F1. In models 25-41, the structure is made of a frame realised in anodised<br />
aluminium borders, coupled with aluminium angular joints. The closing panels are made with galvanised sheet with internal thermo<br />
acoustical coating in flexible polyurethane with open cells (density 30 kg/m3), flame retardant in class F1.<br />
CONDENSE COLLECTING TANK<br />
It is made with galvanised sheet, with the outlets located on both sides of the unit in models 6-18.<br />
FANS<br />
In models 8-18 they are forward bend blade centrifugal, coupled three speed single phase, with direct dragging through splined<br />
electric motor on the fans shaft, whereas in models 25-41 a centrifugal fan with forward bend blades coupled with an electric motor<br />
through belt/pulley transmission is mounted; high prevalence for centralised installation with ducts; the rotors are balanced both<br />
statistically and dynamically to reduce to a minimum vibrations and noise; for the models 6-18 and upon request, they can be<br />
mounted with air flow upwards or downwards (see dimensional layouts).<br />
CONDITIONING COIL<br />
Made with copper pipes and aluminium flanges, is provided with condense collecting tank; in the direct expansion versions<br />
(<strong>UTA</strong>/<strong>UTA</strong>H Echos) it is complete with thermostatic valve and by-pass with check valve only in “heat pump” version (<strong>UTA</strong>H Echos).<br />
AIR FILTER Made with flame retardant synthetic fibres in class F1; maximum separation degree 85% ASHRAE 52-76 Atm (G3<br />
compliant to EUROVENT 4/5).<br />
