220V 380V 440V metal outdoor electrical inverter control cabinet

electric PLC control cabinet design and customized

1.We can make cold storage to implement the intelligent of the PLC control and humanized operation.

2.The product equipment with phase-lack protection,phase protection,voltage protection,oil temperature,liquid level,high-low pressure,motor overload,protective module,flow protection,idle away protection etc.Can automatic process according to protect grade,alarm,can achieve sound and light alarm to remind users.Equipped with fault interlock and remove logic interlock  program,can guarantee to a compressor failure of other compressor can still run normally.

3.Parallel unit can automatically  balance each stage compressor's running time,according to the related parameters such as pressure and temperature range,automatically control number of the compressor,to make it running in the best and most efficient way.save operation cost,also can make the compressor life extended by more than 30% on average.

4.We adopt Siemens PLC and color touch screen to guarantee the quality of control system to make the system running efficiently.We can also provide customized controller.

5.According to the customer's demand,we can make remote control,you can control the whole refrigeration system in your office,We can also make the remote control in the mobile phone.

6.Unit parallel can adjust the quantity and working time of compressors automatically to meet different thermal load.When thermal load of the frozen food is big it will adjust more 

compressors to work when the thermal load is small it will adjust one compressor to do refrigeration.
