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

Replace a defective Siemens PLC of a swimming hall Automation

Corrosion and other environmental factors required the replacement of a S7-313 PLC and its OP7 operating interface by a S7-314 with a touch panel KTP 400 Comfort done by our PLC technicians in the following steps.

  • Schwimmbadsteuerung SPS
  • Schwimmbadsteuerung Schaltschrank
  • Schwimmbadsteuerung Panel
  • - Transmission of the old step 7 program to the new PLC
  • - Programming of the visualization in TIA Portal
  • - link of Step7 project to visualization with TIA Portal
  • - Reconstruction of all PLC components and the new panel to the existing switchboard

Batching Plant for Polyurethane

The latest PLC project of vbk technology is a batching plant with 2 or 3 components for Polyurethane.
Therefor a new SIEMENS S7-1200 CPU is applied with different LCD Touch panels.

  • Software 3K Anlage Grundbild
  • Software 3K Anlage Handsteuerung
  • Software 3K Anlage Kennlinie
  • Software 3K Anlage Rezeptverwaltung
  • The special features of the project are:
  • - recording of the pump duty line, that requires no additional sensor for the volume measurement
  • - choose able operation mode - either installation stops after achieved setting or endless discharge
  • - program is configurable for 2 or 3 components, therewith less maintenance efforts achieved

"Power & Free" conveyor system on a SIEMENS PLC S7-1200

A „Power & Free“ conveyor system of a hand painting equipment for a big manufacturer of windows and doors is the latest highlight of vbk technology automation products. 13 stoppers that need to be free configurable, the control of a traction chain drive as well the automatic suction are made for the operation by a touch panel.

  • Power & Free Fördersystem PLC
  • Power & Free Fördersystem 1
  • Power & Free Fördersystem 2

An especially designed functional module allows simple scalability for the present application as well as for upcoming projects. Currently this functional module is used to set minimum dwell time and maximum number of traverses per stopper by the customer.

The program is done on SIEMENS PLC S7-1200 via TIA-Portal V14.

HVAC Visualization - uniquvis

After completion of the HVAC-plant with our partner KälteConcept at Schwarzbach Feinkost GmbH end of 2015, we now handed over the access at an IT-level to our very interested client. With the uniquvis systems the heating - ventilation - air conditioning plant is fully visualized.

A MySQL database with more than 20 tables provides all data for the visualization. An HTML5 application, which could be accessed by each modern browser, is used for configuration and operation of the visualization.

Control and Visualization of HVAC plant

Having realized the main control of a few smaller refrigeration plants by SPS-S7 for our partner KälteConcept over the year 2015, we are now proud of having been able to contribute to the reopening of the Schwarzbach Feinkost GmbH. With an extraordinary level of heat recovery, we realized an overall concept of heating, ventilation and air conditioning (HVAC) in record time, to allow the owner to deliver their products to their markets.

Control and Visualization of HVAC plant

In addition to switchboard design, SPS-programming and the commissioning, a special highlight is awaiting our engineers - the visualization of the whole HVAC plant.
