VLS / VLH / VLC 604-1204
protection against freezing at low ambient temperature when the unit is
switched off.
Maximum working pressure is 10 [bar] water side and 45 [bar] refrigerant side
6 Condenser
In Heat pump version (VLH), Condensing unit (VLC) and Total heat recovery unit
(VLR), condenser coils are made of seamless copper tubes, arranged in
staggered rows, mechanically expanded into corrugated aluminum fins.
In Cooling only version (VLS) condenser coils are microchannel type, made of
100% aluminum (fins, tubes and headers) with the exception of copper pipe
couplings. Additional surface coating is provided for the standard delivery in
order to further improve resistance to corrosion.
7 Condenser fans
Basic units (in all different sound versions) are equipped with axial fans, direct
drive with asynchronous three-phase motors.
Special fan with electronic brushless type motors are used in HT and HPF
versions.
Fans are equipped with externally mounted nozzle profile housing generating
low sound levels
