Features
  • Analog pressure input for the control of suction pressure or
  • Two different setpoints directly selectable (e.g. for night setpoint)
  • Freely-selectable minimum and maximum frequencies
  • Possibility to select up to three skip frequencies
  • Special function "freeze protection of the evaporator" for use in air-conditioning systems and chillers can be activated
  • Testing and filling the system possible without using an external sensor 
  • All FrigoSoft-advantages also available when using an external control system 
  • Control of the oil pressure switch in large capacity compressors 
MotorMaster Frequency Inverters
  • Our applications support will be pleased to assist with adapting the inverter to the compressor used
  • Easy connection to the external control system (safety switches, motor protection, etc.)
  • Analog setpoint and measured value inputs can be set for various ranges 
  • RS232 interface integrated as standard
  • LON-Bus interface for building management systems on request


NEW: The FrigoSoft-Software is integrated in the inverter. This results in simple minimum-time commissioning.

  • Calculated evaporating temperature
  • Setpoints
  • All motor data (power, frequency, setpoint, etc.)
User benefits  
Improved refrigeration quality 
  • Practically ideal and constant pressure in the suction line, also under alternating system load. 
  • Reduced temperature fluctuations in the refrigerated areas.
Energy saving
  • Up to 40% energy saving due to stepless power control
  • The evaporating temperature may be increased 
  • No peakloads by soft starting of the compressor 
Increased power
  • 20 % higher compressor capacity compared to 50 Hz supply due to 60 Hz operation conditions 
  • Higher C.O.P. factor at part load operating conditions
Extended lifetime 
  • Closed-loop control eliminates pressure surges in the cooling circuit
  • Adjustable timer to prevent frequent compressor starting at minimum demand levels
Ready for extention
  • Two stage operation possible as standard, third stage on request. Soft start of second stage compressor is recommended (KIMODUL, LEKTROMIK)
Safety
  • Automatic restart following a supply interruption or system fault 
  • Numerous supervision functions integrated in the software
