Freezing system protection and regulation device:

★ Adopting international products that are precise, stable, safe, and reliable.

Freezing system protection devices:

World famous devices are used to make sure correct, stable, safe and reliable.

High pressure protection system:

High pressure protection device

When the exhaust pressure of the system exceeds the allowable pressure, the operation of the refrigeration unit will be automatically cut off to prevent accidents from occurring.

When system’s air discharge pressure exceeds allowed pressure, machine automatically stops working, to avoid an accident.

Oil pressure protection system:

Oil pressure protection system

When the freezer is in long-term operation, monitor the oil pressure of the freezer at any time to prevent damage caused by oil shortage.

When freeze dryer are running for long time, system monitor oil pressure, to prevent oil lack damage.

Motor temperature protection system:

Motor temperature protection system

When the temperature of the freezer motor exceeds the set value, in order to protect the freezer, the system will automatically stop the operation of the freezer.

When motor temperature is over set point, this system will automatically stop running the machine to protect it.

Low temperature return oil regulation system:

Low temperature oil return

Adjustment system

It is very important to ensure the smooth return of refrigeration oil to the crankcase when the refrigeration unit operates at a very low evaporation temperature for a long time (a lack of refrigeration oil in the system often leads to the refrigeration unit)Burn it down. When there is a lack of refrigeration oil in the crankcase, the system will automatically start to establish the appropriate oil level in the crankcase. Create conditions for unmanned operation of freeze-drying machines.

When freeze dryer worked long time in low evaporating temperature, it is very important to make refrigerator oil return to crankcase. (Lack of refrigerator oil can cause compressor burn down). When crankcase lacks refrigerator oil, this system will automatically start to establish proper oil level in crankcase. This is to create condition for realizing unmanned operation.
