ARC/SSL 4231÷5281 Y
Super silenced Remote air cooled Condensers with axial fans
These Remote air cooled Condensers with axial fans are designed to be combined with evaporating units set up for R134a 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, except the V shaped ones, can be installed with either horizontal or vertical air delivery, as needed and can be equipped with high efficiency EC fans.
On request, units can be set up for R513A refrigerant.

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.
- R134a refrigerant. On request R513A refrigerant.
- 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.
