Features
• Twenty-four sizes with nominal cooling capacities from 267 to 1682 kW.
• The ideal solution for industrial and commercial applications with optimal
performances and maximum quality. Units designed to operate up to 55°C.
• Exceptional full load and part load energy efficiency: Eurovent energy efficiency
class A and B (unit with high-efficiency option 119); standardised Eurovent
values in accordance with EN 14511-3: 2013: EER up to 3.3 and ESEER up to 4.2.
• Available in two versions: one with very low noise levels and superior energy
efficiency; the other with optimal energy efficiency to minimise operating costs.
• Twin-rotor screw compressors with high-efficiency motor and a variable
capacity valve for exact matching of the cooling capacity to the load.
• All-aluminium condenser (MCHE) with high-efficiency microchannels and high
corrosion resistance.
• Use of R-134a refrigerant with zero ozone depletion potential - the microchannel
heat exchangers reduce the refrigerant charge by 30%.
• Low-noise 4th generation Flying Bird fans made of composite materia l.
• Pro-Dialog+ control system.
• Flooded shell-and-tube evaporator.
• Economizer system with electronic expansion device to increase cooling capacity.
• V-shape condenser coils allow quieter air flow across the coil.
• Simplified electrical connections.
• Units are run-tested before shipment and include a quick-test function for fast
commissioning.
• Leak-tight refrigerant circuit.
• Comprehensive endurance tests.
• Aquaforce offers multiple remote control, monitoring and diagnostic possibilities.
