Product Characteristic:

1. Under vacuum condition with low temperature evaporating
According to the formula for temperature and pressure, for certain volume of the liquid, the lower the pressure, the lower the boiling point of the liquid. Low temperature vacuum evaporator is based on this principle, through reducing the internal pressure of the evaporator, improve the vacuum degree, reduce the boiling point of the liquid, and then improve the evaporation speed of the liquid.

2.Dual use of cold and heat source for lower energy consumption
With the operation of refrigerant compressor, while changing the pressure and state of the refrigerant will change its temperature. Control refrigerant exothermic heating when in contact with the material, the refrigerant will be cooling and liquidation, temperature drop. Then transfer the refrigerant to vapor condensing area through pipe. Using low temperature refrigerant to condense water vapour, refrigerant absorb heat and gasification again and flow into the compressor for cycling . Such dual using of cold and heat source reduces the energy consumption.

3.The auxiliary cold and heat source ensures the balance of energy consumption of system evaporation and condensation
Low temperature vacuum evaporator is operated under the condition of low temperature, it will be greatly influenced by the environment temperature. When environment temperature is too low, it needs more energy for refrigerant compressor to heat evaporation. But the cooling end itself are influenced by environmental temperature, the condensation temperature is low, it needs less energy consumption,  such imbalance energy consumption increase the energy consumption of the compressor.
When in summer time with high environment temperature, the low temperature evaporator is more greatly influenced by environment temperature. High environmental temperature will cause compressor over load while condensing. But absorb too much heat to exhaustion and cause malfunction of compressor.
With patented technical control, our low temperature vacuum evaporator has fully considered the variation of environment temperature, and will start auxiliary cold and heat source to make sure the inner temperature is within control range, and the compressor will be operated within allowable range.

Advantage of Low Temperature Vacuum Evaporator:
  • Complete system with integrated design and fabrication, compact structure, space saving, easy installation, instant utilization only with connection of water and power supply.
  • Low requirement on public supporting facility, without steam supply, complete with heat pump for circulation, cooling water is self generated by condensing water, no requirement for exterior cooling water supply.
  • System operation stable and reliable
  • Energy saving, the running cost is much lower than traditional evaporator
  • Low requirement for pretreatment and after treatment, easy operation for complete process flow
  • Water quality in low temperature is good for recycling and utilization.
  • Completely automatic control with PLC system, applicable for unattended operation.
  • With mobile equipment wireless remote control and monitoring, can realize instant getting the operation status of equipment
  • Low temperature evaporating is suitable for heat sensitive material without qualitative change, the concentrate can be recycled or treated by third party.

Comparison Sheet:
ItemTraditional EvaporatorLow Temperature Vacuum Evaporator
Public UtilityNeed steam and electricity and cooling water supplyNo need for steam, with self generated cooling water, only need power supply
Space CoverMulti assembly and separated with big space cover and many utility engineeringComplete integrated design with compact structure and small space cover
AssemblyLarge assembling project on site, with long period and commissioningConvenient assembly and short period for commissioning, instant operation with connection of water and power supply
Operation TemperatureWith 80ºC to 100ºC evaporating temperature will cause material Deterioration degradation and volatilization and easy scaling.With 35ºC to 40ºC evaporating temperature, keep material original character with less scaling for easy cleaning
SafetyHigh temperature cause high pressure of heater with higher riskLow operation temperature and negative pressure with reliable and stable operation
PerformanceMaterial will be easily degradable under high temperature and pollute the condensate waterThe material is stable under low temperature and keep condensate water quality good
Automatic levelWith PLC control system, but need specially assigned person with high manpower cost.With PLC control system, also with computer and mobile phone instant monitoring and remote control of operation state and report with unattended operation
MaintenanceWith more supporting equipment and inner corrosion and scaling problemLess supporting equipment, less direct contact between evaporator and material, so less inner corrosion or scaling
Running costwith energy loss during operation, manpower cost is highOnly power supply, low energy loss,low manpower cost
