Technical specifications

LRE is the new Galletti series of motor-driven evaporating unit for indoor or outdoors (with IP54 electrical panel option) 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 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, LRE 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 the cooling and electrical systems makes LRE motor-driven evaporating units state of the art in terms of efficiency, reliability, and operating limits.
In fact, the possibility of producing water down to -8°C and condensing with maximum temperatures of 60°C is guaranteed, in order to ensure minimum space requirements for the external fan unit even in the hottest climates.

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.

It is also possible to provide an oil recovery kit inside the refrigerator compartment to prevent it from being trapped in the connection refrigerator lines between the indoor unit and the external condenser when the distances, due to the requirements of the installation site, are characterized by long lengths. Finally, the advanced microprocessor that regulates the operation of the unit allows: the control of a maxium 2 user-side pumps, on/off or modulating, the possibility of cascade connection up to 6 units and the control of the modulation of the air flow in the remote condenser unit with single or double 0-10V signal.
