Description

The iProRACK family of electronic controllers manages racks with standard refrigerants, CO₂ subcritical applications and transcritical CO₂ booster systems. It directly controls the high pressure valves, heat recovery systems and parallel compression. The iProRACK series is designed for all kind of compressor racks (scroll, semi-hermetic, multi-stages, different capacity and screw compressors).

The series is characterized by the most advanced technology in connectivity and processing speed. It is based on a powerful platform that includes one hardware configuration that is able to expand the actual solution in the market. Among main features: 10 conf. probe inputs, 10/15 conf. relays, 20 conf. digital inputs, 6 analog outputs, Ethernet and USB (host) communication ports, 200MHz CPU, 128MB flash memory capacity, 32bit processor and RS485 serial output.

The iProRACK family comprises one model in 4 DIN format (IPR208D), two in 10 DIN format (IPR215D for standard applications and IPRC215D for CO₂ transcritical applications) and two expansion modules, (IPX206D and IPX215D). There is also the possibility to connect up to two XEV20D drivers for the stepper EEV management.

An intuitive and useful HMI is given by the Visograph 2.0 (graphic LCD display) or Visotouch (touch screen display), which gives concise information about the variables of the compressor rack.
