A CO2 refrigeration system 1 having a compressor 3, an electronic control system 13 including a processor device 15. The processor device is arranged to control the compressor 3 according to input signals received by a temperature sensor 17 and/or a pressure sensitive device 31. The control system may be arranged to compare temperature output from a gas cooler 5 with a temperature stored in memory and deactivate the compressor and/or generate an alarm signal. The pressure sensitive device may be a pressure operated switch 31 arranged to open and close at set pressures and where the control system is arranged to monitor the state of the switch and control the compressor according to the switches state. The arrangement may include a rupturing device arranged to rupture at a set pressure, the control system arranged to operate the compressor to maintain pressure in the system below the rupturing pressure. |
