GEA CAIRfricostar - CS Klimateknik

Dehumidifier with Air Mixing and Heat Pump FunctionType CMPGEA CAIRfricostar– With optimized heat exchanger combination for maximum COP values, mounted onanti-vibration mounts, circuit includes filter drier, liquid collector, thermostaticexpansion valve with MOP (maximum operating pressure) and external pressureequalisation, all necessary shut-off valves, monitoring and safety devices(pressostat, icing sensor, etc.)Droplet eliminator – Made of plastic with an aluminium frame at air velocities on supply and exhaust sideexceeding 2,5 m/s is necessaryFan unit:GEA „OPTIVENT“– High performance fan impellers with coated backward curved blades, one side suctionand blades directly connected to motor shaft; Performance– Optimized high value three-phase motor, B3 model type, protection type IP55, insulationclass F adjusted for operation with a frequency converter. Fan and motor unitincluding coated intake nozzle mounted on buckling resistant and coated base construction,motor and fan have sound attenuated bearings– Continuous measurement of pressure effects– Statically and dynamically balanced according to DIN ISO 1940, part 1, G2,5). Continuousmonitoring of operation using DDC. Frequency converter for each motorinstalled in or mounted on the unit, control via GEA DDC with a separate analoguesignal for both motors. Frequency converters are adjusted and set for both motors.Limit values for motor current and fan speed are set by the programme– Resonance frequency band/fade out set by factory– Automatic energy optimization for optimal energy use and efficiency rate– Multiple motor operation is possible– Voltage intermediate circuit converter without reduction of capacity– Continuous speed control– Operating hours counter– Min. and max. speed limitation, automatic ramp curve function UP/DOWN– Automatic motor adjustment– Motor tracing switch– DC break– Variable clock frequency– Motor protection– Short circuit and short circuit to earth safe– Under and over current protection– Phase fault monitoring– Motor coils for reducing speed of voltage rise du/dt (delta voltage/delta time)– Numerical display for queries and entering of different indicators on operating status:control setpoint, motor frequency, actual value and setpoint, motor current,motor torque and capacity, intermediate circuit voltage, thermal motor load, thermalfrequency converter load, control and programmable display with copy function,production according to ISO 9001, CE Label, net and main shaft protectionaccording to VDE 0160, radio interference shielding, codes and regulations on electromagneticcompatibility conform with EN 55011 Kl.B-1; EN 50082-2, electric insulationof control and power components according to VDE 0106/0160 (The use ofearth leakage circuit breaker / fuse with frequency converters NOT possible!), volumeflow measuring device via ring measuring line and pressure measuring pointin fan. Calculation and evaluation of volume flow via the GEA DDC. The settings forentire unit are done at the factory. Continuous safety monitoring via safety chain inthe unit. Display and settings via GEA DDC.24 PR-2008-0327-GB • Subject to modifications • Status 09/2008
