XJQ -E Series Box Type Condensing Units
1. Product description :
According to demands of market, we design this new series XJQ-E on basis of XJQ series. This new series products feature box type structure with hermetic compressor and control box, which is Compact and pleasant looking, applicable to cold display cases, cold storage rooms, ice producers etc. The applicable temperature ranges are:-5C~ 15°C, -5°C~5°C and -15~-25°C. They can bewidely used in hotels, restaurants, medicines, agricu ltural, chemicals i ndustries all other place where cold storage is needed.Features of these series products:
◆ Electric components were added on the basis of old XJQ series,induding condensing unit, main control board, cold roomtemp control board and operation board. Cold room temp control board and operation board are optional.
◆ Main control board can start/stop compressor by system low voltage, be suitable for super market, milk container,water chiller etc. If all optional included, system can control compressor by tem p., with function of temp. and defrosting adjustment. The complete set of control system can be used for cold room directly, no extra controller required.
◆ With multi protections incuding phase protection, phase lack, over current, too constant start of compressor, discharge temp and system high/low temp.
◆ With fan speed regulator, to adjust condensing fan according to condensing temp.
◆ With operation data display function, to check operation current of compressor, discharge temp. and condensing temp.
◆ With system alarm function. When fault effects, the system will make alarm beep sound to remind user.
◆ The operation board can show temp. setting, defrosting control, operation system data checking and cold room temp. alarm functions. It can be installed apart from condensing units for remote control.
