LSLG SERIES SCREW COMPRESSOR CHILLERS
Feature：
●Twin screw compressor of world famous brand is employed,with high efficiency,low noise level,.less wearing and long operation time.
●The unit is of high performance as they are made of the condensers and evaporators of grooved copper pipes,and high quality components,by specialized process.
●The unit is of easy to operate,and fridendly interfaced,they employ leading brand of PLC,64K color touch scuch screen and other control elements.
●The energy saving for Multi-capacity regulation,resulted in cost cut down for operation and maintenance.
Control system
●Lmaged system operation chart,showing the temperatures of water in and out,the energy level of compressor run,on/off button,run time,alarm etc.And the remote turn on/off function is available.PC remote control is optional.
●Notice for maintenance is indicated according to the accumulated run time of the compressor.it is a convenience to the maintenance man
●The control system will automatically balance the run time for each compressor for the mult-compressor unit
safety protections
●discharge check valve:it prevents the dischged gas from going back after the compressor stop;
●phase lack protection:it protects the compressor for over high voltage,voltage deficiency,and phase lack;
●direction:it protects the compressor from damage resulted from counter directon run;
●oil heats:it heats the oil before the unit start,keep the good lubrication for the unit before it runs;
●overheat protection inside the motor of the compressor;it protect the compressor from burning down for too high coil temperature for overload,or abnormal run condition.
●high and low pressure protection;it protect the compressor and the system against extreme run condition and trouble.
●freezing protection;it protects the unit from run withot water flow.
●high temperature of chilled water protection;it works to protect the compressor in case the load is too large;the temperature of the chilled water is ton high.it may result in compressor failure without ZFLthis protect in the case.
The gas refrigerant of high temperature inside the condensing coils,after transferring its heat to the air and spraying water outside the coils,gradually condenses,becoming liquid.The heat transfer is remarkably reinforced by the spraying water covering the surface of everywhere of the coils by strong wind of the fans.Absorbing the heat from the refrigerant,the temperature of the water and the air raises,and some of the water evaporates,with large quantity of heat as the latent heat is taken away in the vapor.The liquid water in the hot air is held in the PVC layer,is cooled by the air flowing by,and collected in the water receiver,The circulating pump will push the water in to the spraying,continue the circulation.The water lost will be replenished by the water level regulator.
Product features
●Small investment
Similar to a cooling tower,the ZFL series evaporative condenser has included pump,water receiver,and PVC heat transfer layer,but with much compact structure,thus the mounting cost is remarkably decreased.lt is easy to mounting,only fixing the upper layer,but with much compact strucure,thus the mounting cost is remarkably decreased.lt is easy to mounting,only fixing the upper and below parts with in site,connecting pipes and electrical systems.Compared to other condensers,the primary investment is much lower.
●Good operation effect and low investment
With high efficiency,saving water,energy and space,much fewer components,the ZFLevaporative condenser is much more economical.
