Compressor Racks for Blast Freezers

Together with our Partner KälteConcept we finished a plant with several compressor racks for blast freezers, spiral cooling conveyors and frozen storages with cold and warm brine generation on a Siemens PLC S7-1500 CPU programmed with TIA-portal.

  • Compressor Racks Dashboard
  • Compressor Racks settings
  • Compressor Racks cold brine
  • Kaskaden-Verbundanlage R723
  • Compressor Racks Blast Freezer
  • Compressor Racks Warm sole

In total the plant consists of:

  • - 4 R723 compressors, one controlled by Variable Frequency Drive (VFD) the other 3 compressors in a 2-step-control mode
  • - 3 CO2 compressors for a blast freezer, one VFD-controlled
  • - 1 compressor for frozen storage, VFD-controlled
  • - defrosting, blast freezers and frozen storages with warm brine
  • - 3 integrated rack controllers for demand oriented supply of the refrigerating capacity
  • - demand oriented control of a R723 condenser
  • - heat recovery for warm brine generation
  • - controlled warm brine flow to reduce the thermal stress of the evaporator while defrosting
  • - cold brine charge cycle with pump redundancy to compensate for different operation hours

Service uniqunet – FFUs in Cleanroomapplication

„Troubleshooting - Commissioning - Training“ were written at the P.O. of a big plant engineering company. They pleased us for support for commissioning a FFU-network with fans from ebmpapst with Modbus Interface at site and to train the operating staff afterwards.

After an address-conflict was eliminated in the FFU-network and no other abnormalities were found we did the programming of the uniqunet FFU-control device together with the end user. Now 3 FFU groups will be controlled according to the manufacturing process with different set-values in day/night mode.
