Super silenced Remote aircooled Condensers with axial fans

These Remote aircooled Condensers with axial fans are designed to be combined with evaporating units with R410A refrigerant.
These units, available in three configurations depending on the level of noiselessness required, Standard, Silenced and Super silenced, are equipped with latest generation axial fans, with motor fan shrouds having a large radius of curvature to eliminate all the air flow turbulence and with larger plenum to uniform the air distribution on the cooling coil.
The units can be installed with either horizontal or vertical air delivery, as needed and can be equipped with high efficiency EC fans.

Versions

ARC/SSL - Super silenced cooling only units with horizontal air flow
ARC/EC/SSL - Super silenced cooling only units with horizontal air flow and EC Inverter fans
ARC/VX/SSL - Super silenced cooling only units with vertical air flow
ARC/EC/VX/SSL - Super silenced cooling only units with vertical air flow and EC Inverter fans

Power range

1.5-18.0 m³/s
3071-37912 Cfm

Features

Frame in oven painted with a polyurethane resin and galvanised steel casework.
The cowlings of the motorfans are made with a wide bending radius to eliminate any turbulence in the air flow.
Heat exchanger is made with corrugated tubes with a greater heat exchange surface, fins cut with a special louver configuration to give the best external coefficient of heat exchange.
Electrical board includes: main switch, fuses, fans wiring, terminals for external connections, fans speed controller via 0-10V signal.
Electrical board (EC versions) includes: main switch, automatic circuit breakers, fans wiring, terminals for external connections, therminals for 0-10V signal for fan speed control.
