3 LCAEX General features FRAME Open self-supporting galvanized steel frame protected with polyester powder painting. The open frame make easy maintenance and service activities while the unit is in operation. As option a protection grid is available. COMPRESSORS Semi-hermetic «double screw» type with a built-in thermal switch protection motor complete with: suction and discharge shut-off valves (option), oil separator, step control, crankcase heater, oil level switch (option), oil sight glass, safety thermostat, oil strainer, suction strainer, liquid injection device. EVAPORATOR Shell and tube type, made by copper tube and steel shell and with two independent refrigerant circuits and one water circuit. The thermal insulation is made of flexible closed-cells lining. As protection CONDENSERS Double circuits made of several copper tube and aluminium finned coils. They are connected to make two refrigerant circuits FANS Axial fans with aerodynamic outline blade, directly couplet to a three phase electric motor with external rotor. A safety fan guard is fitted on air flow discharge. REFRIGERANT CIRCUITS Each unit is supplied with two or more independent refrigerant circuits; each one includes: filter dryer, refrigerant sight glass, solenoid valve, thermostatic electronic valve with external equalizer, liquid line shut-off valve, service valve, HP/LP gauges with shut-off valves. To protect the refrigerant circuit the following devices are installed: automatic reset low pressure switch, manual reset high and safety pressure switches, safety valve, antifreeze thermostat. ELECTRICAL BOARD Weather proof type with protection grade IP 54. It includes: main circuit automatic breaker with locking door device, main fuses, compressor contactor and fuses for the star/delta start or part winding; fans contactors and fuses, auxiliary circuits transformer; Microprocessor to control automatically the unit with a visual system to display the function as well as failures Versions DS Partial condensing heat recovery. Each refrigerant circuit includes a desuperheater insulated and installed in series between the compressor and the condenser. RCS Condensing heat recovery from 70% to 90%. Each refrigerant circuit includes a heat exchanger shell and tube type insulated and mounted in series between compressor and condenser. Condensing control through pressure transducer. RCP 100% condensing heat recovery. Each refrigerant circuit includes: a heat exchanger shell and tube type insulated and mounted in parallel to the condenser and the relevant solenoid valves. P Hydraulic kit version. It includes: one or two pumps (one as stand-by pump) expansion vessel, safety valve, air purger, hydraulic circuit insulated and with flowswitch, shut-off valves and, in case of stand-by pump, non-return pump. Relevant electrical circuit. As option, pumps with higher ESP are available. PAC Version with hydraulic and inertial storage tank. It includes, further to what included in the P version, a storage tank installed on the return line. The storage tank includes the evaporator. LN Low noise version, it includes pressostatic fan speed control and special soundproofing for the compressor chamber. VLN Very low noise version. Further to the LN devices, this version is equipped with very low speed fans and extra insulated compressor box. Options Power factor correction. Fan speed control. Remote control panel. Clock card. RS 485 card. Evaporator electrical heater. El. Heater for PAC version. Compressor shut of valves. Cu/Cu condensing coils. Flowswitch (STD on P and PAC versions). Pump shut off valve.
