(1) data referred to the following conditions :
internal exchanger water = 12/7°C
outside air temperature 35°C
(2) According to EUROVENT the Total Power Input does not consider the
pump share, required to overcome the pressure drop for the solution
circulation inside the exchangers.
(3) DSW = twin-screw compressor
(4) S&T = tube bundle
(5) AX = axial-flow fan

Note: the Standard unit shall never be exposed, at temperatures below -
10°C while supplied. On request it’s possible to take countermeasures for
the operation also in more critical environmental conditions. For special
conditions contact our Sales Office.
Warning: the still air condition is meant as absence of air flow to the unit.
Any wind condition can let air pass through the condenser coil thus
worsening the operating limits of the unit (see limits with air speed at 0,5 m/s
& 1 m/s). In order to avoid such situation, windbreak barriers are necessary.
The minimum ambient temperature is given for units equipped with low
ambient control or with ECObreeze fans. For standard unit without these
options, this value is of about 18°C with still air and unit operating at full
load.
