Total heat recovery multi-purpose units LEP Indoor monobloc water-water unit LEP 50-40 kw Maximum efficiency with total recovery and dissipation in water.

1 Total heat recovery multi-purpose units LEP Indoor monobloc water-water unit LEP kw Maximum efficiency with total recovery and dissipation in water. Total heat recovery multi-purpose unit Multi-purpose unit - -pipe system Multi-purpose unit - 4-pipe system Scroll compressor R-40A R-40A refrigerant Cooling / Heating LEP units are actually multi-purpose, they totally recover the condensation heat and they are characterized by the simultaneous production of cold and hot water. Available for two-pipe systems with the request of DHW production or in four-pipe systems, they are conceived for averagehigh power applications (multi residential or commercial unit) and they guarantee a high thermodynamic efficiency and a wide configurability both in terms of accessories and in terms of refrigeration cycle. LEP series is characterized by a reduced size, high thermodynamic cycle COP, no external noise, reduced cooling load and it is composed of 4 models with refrigeration capacity ranging from 50 to 40 kw both for the standard version and the silenced one. Multi-purpose LEP machines have six water connections linked to three different hydraulic circuits of which a dissipation one (hot or cold) opposed to the consumption. The users differ as for two-pipe system in which there is a hot/cold circuit and just one hot circuit for the production of DHW while in four-pipe systems there is one hot circuit and a cold one. There is the option to obtain an external sound-proof hydraulic module with circulation pumps for dissipation circuits, users and domestic hot water. PLUS Maximum energy efficiency Total condensation heat recovery Electronic expansion valve Up to 4 compressors Remote connectivity to the most common protocols. Compact dimensions Low-noise level thanks to the paneled structure. LEP is suitable to the air-conditioning of -pipe systems with production of DHW or in 4-pipe systems. In both, the total recovery of the heat ensures remarkable energy savings. 30 galletti.com VM0003-C

2 LEP kw OPERATION MODE LEP-M: chiller mode In the Chiller mode the unit cools water to air condition the interior on the user side, dissipating the condensation heat by means of water that is cooled in the dissipation exchanger. LEP-M: chiller + DHW In the Chiller + DHW mode the unit can produce chilled water with the simultaneous production of high-temperature hot water for sanitary use, thanks to total heat recovery. LEP-M: DHW mode In the high-temperature sanitary hot water (DHW) mode the unit heats water in the condenser, dedicated to DHW as needed, dissipating the evaporative cooling capacity by means of water that is heated in the exchanger on the dissipation side. LEP-M: heat pump mode LEP-P: 4-pipe systems In the heat pump mode the unit heats the water in the condenser to warm the interior on the user side, dissipating the evaporative cooling capacity by means of water that is heated in the dissipation exchanger. CONFIGURATION The models are completely configurable by selecting the version and the options. To the right is shown an example of configuration. AVAILABLE VERSIONS -pipe system versions LEP..MS Standard execution LEP-ML Low noise execution CONFIGURATION OPTIONS The four-pipe system has a distribution system that offers both hot water (with respective return lines) and chilled water (with respective return lines). The LEP-P unit has a circuit used for the production of hot water and another one used for the production of cold water. - POWER SUPPLY 0 400/3/50 + N 400/3/50 + N + Circuit breakers - CONTROL MICROPROCESSOR AND THERMAL EXPANSION VALVE B Programmable (LCD x display) + electronic expansion valve 3 AIR FLOW MODULATION SOURCE SIDE 0 Absent P Condensation control with -0V modulated output signal 4 AIR FLOW MODULATION USER SIDE 0 Absent D Air flow modulation with output signal in ΔT logic = cost T Air flow modulation with output signal in T logic = cost 5 - REMOTE COMMUNICATION 0 Absent RS45 Serial board (Modbus or Carel protocol) Lonworks serial board 3 GSM modem kit 4 Ethernet card (SNMP or BACNET protocol) + clock card 5 Ethernet card + clock card + supervision software - VIBRATION ISOLATION 0 Absent G Rubber vibration dampers at the base of the unit M Spring vibration dampers at the base of the unit - PACKING 0 Standard Wooden crate Wooden case Version Fields LEP4ML B P 0 G 0 0 B To verify the compatibility of the options, use the selection software or the price list. 4-pipe system versions LEP..PS Standard execution LEP-PL Low noise execution - REMOTE CONTROL 0 Absent 3 Remote display for programmable microprocessor 9 INSULATED EXTERNAL HYDRAULIC MODULE SEPARATED FROM THE MAIN UNIT 0 Hydraulic module not present A LP user pump + LP dissipation + LP recovery B LP user pump + LP modulating dissipation + LP recovery C LP user pump + HP dissipation + LP recovery D LP user pump + HP modulating dissipation + LP recovery E HP user pump + LP dissipation + LP recovery F HP user pump + LP modulating dissipation + LP recovery G HP user pump + HP dissipation + LP recovery H HP user pump + HP modulating dissipation + LP recovery I LP user pump + LP dissipation + HP recovery J LP user pump + LP modulating dissipation + HP recovery K LP user pump + HP dissipation + HP recovery L LP user pump + HP modulating dissipation + HP recovery M HP user pump + LP dissipation + HP recovery N HP user pump + LP modulating dissipation + LP recovery P HP user pump + HP dissipation + LP recovery Q HP user pump + HP modulating dissipation + LP recovery Total heat recovery multi-purpose units - LEP ACCESSORIES A Power factor correction capacitors B Soft-starter kit C Service kit (kit of sensors for quick diagnosis) D ON/OFF status of the compressors E Outdoor temperature probe for setpoint compensation F Pressure gauges G Six Victaulic couplings for quick water IN-OUT connection H Regulating filter kit (solenoid and tap on the liquid line) I 4-way flow reverse valve on user side in hydraulic module VM0003-C galletti.com 3
