Dehumidifier with Air Mixing and Heat Pump Function
Type CMP
GEA CAIRfricostar
– With optimized heat exchanger combination for maximum COP values, mounted on
anti-vibration mounts, circuit includes filter drier, liquid collector, thermostatic
expansion valve with MOP (maximum operating pressure) and external pressure
equalisation, 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 side
exceeding 2,5 m/s is necessary
Fan unit:
GEA „OPTIVENT“
– High performance fan impellers with coated backward curved blades, one side suction
and blades directly connected to motor shaft; Performance
– Optimized high value three-phase motor, B3 model type, protection type IP55, insulation
class F adjusted for operation with a frequency converter. Fan and motor unit
including 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). Continuous
monitoring of operation using DDC. Frequency converter for each motor
installed in or mounted on the unit, control via GEA DDC with a separate analogue
signal 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, thermal
frequency converter load, control and programmable display with copy function,
production according to ISO 9001, CE Label, net and main shaft protection
according to VDE 0160, radio interference shielding, codes and regulations on electromagnetic
compatibility conform with EN 55011 Kl.B-1; EN 50082-2, electric insulation
of control and power components according to VDE 0106/0160 (The use of
earth leakage circuit breaker / fuse with frequency converters NOT possible!), volume
flow measuring device via ring measuring line and pressure measuring point
in fan. Calculation and evaluation of volume flow via the GEA DDC. The settings for
entire unit are done at the factory. Continuous safety monitoring via safety chain in
the unit. Display and settings via GEA DDC.
