Water chillers and heat pumps WRE Indoor packaged unit Available from June 2020 Water-water unit with high seasonal efficiency Scroll compressor Cooling only Heating/ Cooling Electronic expansion valve Up to 6 compressors 1 or 2 cooling circuits Remote connectivity with the most common protocols Compact dimensions 3 di erent acoustic con gurations High seasonal e ciency values WRE is the new Galletti series of self-contained reversible heat pumps and water chillers for indoor installation, suitable for both air conditioning and industrial process applications. The range covers capacities from 40 kW up to a maximum of 750 kW and is characterised by extremely high levels of seasonal efficiency (in compliance with ErP 2021 requirements) and reduced space requirements in order to facilitate access to technical compartments (for capacities of up to 560 kW, the width and height are less than 88 cm and 190 cm respectively). In order to increase the efficiency at partial loads, WRE models are provided with tandem or trio solutions (2 or 3 compressors on a single circuit) and equipped with electronic expansion valve as standard. Both single and dual circuit versions are available. The use of top quality components at the cutting edge of technology in cooling, hydraulic, and electrical systems makes WRE chillers state of the art in terms of efficiency, reliability, and operating limits. In fact, the ability to produce water from -8 °C to 55 °C and use any type of natural source for dissipation is guaranteed: soil, ground water, or outside air. The high configurability of the series, which is in the DNA of Galletti, is guaranteed by 2 different versions, with and without closing panels, and 3 different acoustic configurations: standard, low noise, and super low noise, able to ensure a sound power level reduction of up to 12 dB(A). The range of the configuration available is completed by the possibility of producing hot water up to 60 °C at zero cost through partial heat recovery. Lastly, the advanced microprocessor that regulates the operation of the unit allows the control of a maximum of 2 pumps on the equipment side and 2 pumps on the source side, on/off or modulating, the possibility of cascade connection of up to 4 units and management of reversibility on both the gas side and the water side. The possibility of keeping the evaporator indoors means there is no need to add glycol to the water inside the system. In addition, you can keep all components requiring maintenance in an easily accessible room.

COMPONENTI PRINCIPALI Structure Made in galvanised steel sheet with a polyester powder coating for outdoors. On request the compressor compartment is completely sealed and accessible on 3 sides thanks to easily removable panels that greatly simplify all maintenance and inspection operations. Compressori scroll Heat exchangers Scroll-type compressors in a tandem or trio con guration equipped with IDV valve. The IDV intermediate delivery valve technology allows the compressor to avoid losses caused by overcompression and, consequently, the additional work the motor has to perform in...
