1.1.4 Product innovation

LEW units provide excellent thermodynamic performance and maximum flexibility of use thanks to constant product

research. The joint application of scroll compressors, advanced control systems and R410A refrigerant gas achieves

compactcircuitsandhighCOPs.

The possibility of keeping the evaporator on the inside allows you not to add glycol to the water in the sy

stem, with

clear advantages in terms of thermodynamic performance, preservation from corrosion and respect for the

environment. It also makes it possible for all the components requiring maintenance to be installed in an easily

accessiblespace.

Chiller units can be applied even when no dissipation source other tha

n air is available: a water Dry‐Cooler provides

thermalexchangewiththeatmospherewhilemaintainingacompact‐sizedcircuit.

Forlargebuildings,air‐conditioningcanbeimplementedasthefloors/zonesaresoldorrentedbyinstallingaLEWunit

for each floor in a small size technical room, thus spreading the inves

tment over time. The overall dimensions of the

units(lessthan90cmdepthinthehigheroutputsizes)makethemeasytobeinstalledsincetheyfitthroughanydoor.

1.2 Structure

AllLEW seriesunitshavetheloadbearingbaseand panellingingalvanisedsheetmetalpaintedwithpolyesterpowders

and polymerised in the oven at 180°C. The unit has an attractive design and when closed all the components are

inaccessible. This, along with the extensive use of soundproofing material inside the compartme

nt and around the

compressors(availableforthelow‐noiseversion),reducessoundtoexceptionallylowlevels(Lp<67dB‐A@1metrefor

biggersizes).

The hydraulic/chiller connections are envisioned on the right side, when looking at the electrical control board, to

reducethetechnicalspacerequiredforinstallation.Allthepanelsarere

movable(exceptfortheoneontheright, upon

which all thehydraulic connections are fitted) making the unit fully accessible even though routine maintenanceonly

needsaccessingfromthefront.

1.3 Cooling circuit

The cooling circuit is manufactured in our factory, with top brand components and operators trained, according to
