Refrigeration Inverter for the control of 1 to 8 compressors - up to 440 A
The FrigoPack FU+ range of Refrigeration Inverters offers better control performance, efficiency, compressor protection and integrated intelligence
FrigoPack FU+ has been designed for refrigeration systems in small and large supermarkets, hotels, restaurants or in food production and processing facilities as well as for chillers for Aircon and indirect-cooled refrigeration, condensers, dry coolers and more. All modern refrigerants have been integrated in its software.
The modular structure of FrigoPack FU+ inverters allows a flexible spectrum of inverter performance: functionality can be adapted by adding of modules according to the relevant application .
In its basic version FrigoPackEC FU+ (without modules) controls one refrigeration compressor. Control is based on an external signal 0….+10 V (or 4…20 mA), e.g. from a WURM control system.
The economy version FrigoPackE FU+ (with module BM-1) is suitable for the control of evaporation and condesation temperatures (tec/tcb control). Information on the pressure needed is transmitted via HUBA control pressure transmitters and the refrigeration compressors connected (up to 3 with this version) can be speed-controlled effectively and energy-saving. In rack systems with 4 or 5 compressors (or even 6 to 8) the economy version FrigoPackE FU+ may be extended by external modules.
With EM-1…EM-4 External Extension Modules, suction gas superheat and discharge gas superheat may be monitored as additional feature.
Module EM-7 has two inputs for PT-1000 temperature sensors. One PT-1000 senses the ambient temperature for optimized control of condensation, the other is used for suction gas temperature, in order to evaluate superheat and thus protect the compressor.
