Hitachi Air Conditioning Engineered for tomorrow. Utopia IVX Premium IVX Premium offers high seasonal efficiencies, and Hitachi’s IVX technology has all the benefits of VRF, including individual control of each indoor unit with an increased number of twin, triple and quad combinations in addition to delivering excellent part-load efficiency. With cooling capacities and heating capacities from 3.2kW to 37.5kW, a maximum of 8 indoor units are connectable to a single outdoor unit, with individual control and efficiencies achieved as high as A++/A+ (depending on model/combinations). Comfort and ease of installation Improved connectivity (up to 8 indoors per outdoor unit, minimising pipework required) and zone-by-zone individual control makes IVX Premium the perfect solution where VRF flexibility is needed but at a lower cost. Seasonally efficient The individual Thermo-on and Thermo-off is possible even when the remote control is connected to multiple internal units. The system is able to handle changes in air conditioning needs for each individual space, e.g., internal zone or perimeter area, and thereby optimise energy efficiencies. This produces a highly comfortable environment and great electricity savings. New DC inverter compressor for improved low-speed and part-load seasonal performance SCOP of up to 4.65 A+ rating and SEER of up to 6.82 A++ rating. Zone-by-zone control Individual control of multiple indoor units in each zone Adjust temperature settings according to occupancy and external environmental conditions to save on energy. Easy installation Easily adaptable and reconfigurable Each indoor unit can be operated completely independently within the same mode. Controlled from a dedicated remote controller, each room’s occupants can monitor and adjust operating temperatures according to their specific requirements. This facilitates maximum energy savings and total future flexibility, as units have individual control regardless of possible future reorganisation of the interior spaces. Compatibility with R22 pipework New Utopia IVX Premium (and IVX Comfort) are compatible* with existing R22 gas installations. Both models – which use R410A refrigerant gas - can be installed without having to change the existing installed piping as the system adjusts the pressure so as not to damage the existing piping. *some restrictions apply Compact and lightweight outdoor unit Reduced number of outdoor nits and u less pipework required. Improved comfort Slitless fin heat exchanger for improved heating performance Cold draft prevention, frost protection and low noise as standard. Eco friendly Compatibility - Compatible with all Hitachi System Free indoor units All IVX Premium models are ErP compliant, exceeding the 2014 ErP Lot 10 standards. IVX Premium is fully ErP compliant and has excellent A++ seasonal efficiency
