FrigoPack® FU+

Next Generation

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.

Operating FrigoPack FU+

The 4 most important refrigeration values on display at one glance on keypad FU+ PROG:

• Evaporation temperature (dew point)
• Condensation temperature (dew point)
• Suction pressure
• Discharge pressure

New compressor and refrigerant data can be loaded from the SD-MC Memory Card.
