Safety
User access control and security with RFID / Password Protected security lock on the control panel for unauthorized tampering. The refrigeration auto shut off when door opens for Power saving and environment friendly operation. Blocked Filter indicator lights with filters which are removable and washable for cleaning.
HP (High Pressure) Switch
If the compressor is over-pressured, the compressor may overheat and cause a fire. Since we have used HP pressure switch, if the compressor gets over pressured, the supply to the compressor is cut off through relay by the HP pressure switch.
LP (Low Pressure) Switch
If the compressor is Low-pressured, the compressor may overheat and cause a fire. Since we have used LP pressure switch, If the compressor gets low pressured, the supply to the compressor is out off through relay by the LP pressure switch.
Over Heat Protector
If the compressor is Over Heat for any reason, the compressor may overheat and cause a fire. As we use an Over Heat protector, If the compressor gets Over Heat, the supply to the compressor is cut off through the Over Heat protector and the relay.
Over Current Protector
If the compressor draws Over Current for any reason, the compressor may overheat and cause a fire. As we use an Over Current Protector, if the compressor draws Over Current, the supply to the compressor is cut off through the Over Current protector and the relay.
Fan off protection
If the fan off then compressor may Over Heat and cause a fire. As we use fan off protection so the supply to the compressor is cut off through the relay.
