Features
• The ALTO remote condensers cover a capacity range from
24 to 1128 kW designed for commercial and industrial use in refrigeration
and air conditioning applications. All models are available with vertical or
horizontal air flow.
• The ALTO FC dry-coolers cover a capacity range from 17 to 1104 kW for use
in commercial and industrial applications, working with fluids that are copper
compatible. All models are available with vertical or horizontal air flow.
• The ALTO range is designed for outdoor installation, for maximum working
temperature of 60°C and outdoor air temperature from -30°C to +45°C.
• Several fans configurations possib le to match cooling capacity and sound
requirements.
• Single or double raws coils to match pressure drops requirements
• Casing in galvanised sheet steel, powder-painted polyester, resisting UV radiation
and offering excellent corrosion protection.
• The propeller fans ensure a significant sound reduction, while maintaining
high air flow performances. Motors have high-efficiency shrouds to reduce
sound levels and increase the air flow efficiency and are designed to work
with frequency speed control from 50 to 20 Hz.
• All condensers and fluid coolers are Eurovent certified and tested by
independent laboratories in accordance with European Standards. The
performances comply with EN 327 for air-cooled condensers and EN 1048 for
fluid coolers.
• Dry coolers are suitable for cooling water or other fluids that do not corrode
with copper.
• Electrical connections in weatherproof boxes, easy access for maintenance.
• Air-cooled condensers are available with refrigerant R-134a, R-407C and
R-404A.
• The sound power levels are in accordance with ISO 3741 and ISO 3744.
