3 next evo cw 3 AN EFFICIENT ENERGY USE One of the most important characteristics of NEXT EVO CW machines is their high energy efficiency, both at design and at the various operating conditions experienced during the year. The fans electric motors are the brushless type with built-in electronic commutation system (EC) which yield high energy savings during operation in reduced air flow. These electric motors are ensuring high performances, minimum energy consumption and total absence of electromagnetic noise FREE-COOLING The free-cooling system is an important accessory that allows you to maximize energy savings of air conditioning plant The microprocessor controls a dual source free-cooling system: direct free-cooling with direct introduction into the room of ambient air, or water indirect free-cooling with a dedicated heat exchanger. According to the set-point and the energy saving logic. the controller activates the free-cooling system more affordable. THE RC GROUP TECHNICAL SYNERGY IN ENERGY CLASS A RC Group proposes itself as the sole supplier of offering both the air conditioning units and the liquid chillers. The synergy includes the air conditioners NEXT EVO CW and the air-cooled liquid chillers series UNICO TURBO FL. These liquid chillers are equipped with oil-free two stage centrifugal compressors with magnetic levitation bearings, flooded shall and tube evaporator and micro-channel type condensing coil. The 17 proposed models cover cooling capacities from 280 to 1500 kw, all in energy class A with a value of 5.76 ESEER unico turbo fl vo cw

The machine is divided in two sections: the upper part ( A in the picture) includes the high efficiency air filters and the air handling section with a cooling coil available in 3 versions: with 4, 6 or 8 rows. The lower part ( B in the picture) can be placed in the compartment formed by the raised floor and includes the plug-fans. The lower part is also provided with height-adjustable feet to allow the adaptation of the frame to the height of the raised floor. vo cw
