Lounges 2019 - Cleanroomtradeshow

As every year we followed the invitation of an OEM costumer for our fan control devices to visit him at the cleanroom lounge in Karlsruhe.

There we did a lot of interesting talks about the control of fans increasingly under the aspect of IoT.

Booth NICOTRA Gebhardt (Regal Beloit)

Handheld to control and parametrize EC-fans

On of the leading HVAC distributors and contractors in Israel uses, by its own account, mainly EC-fans from ebmpapst and Ziehl Abegg for his appliances.

From now he will program and control it's EC-fans with Modbus- Interface by technologies out of the Vogtland. With that the handhelds of the unqiuom series will be used at 24 countries worldwide.

Control and Visualisation of Air Conditioning at SIEMENS SPS S7

Right in time for the Christmas Business and ordered by a big bakery supplier the control and the suitable visualisation of the Air Conditioning of a donut production line was passed to customer at the gates of Warsaw.

Realised on an S7-1500 programmed with TIA-portal it guarantees the air conditioning of 2 rooms, which could do both, proofing and resting.

FFU Service - Fraunhofer Gesellschaft

With its various institutes Fraunhofer Gesellschaft belongs to the greatest Cleanroom Operators in Germany.

Yesterday a production shutdown was planned in a job-side in northern Germany, used by different companies to perform their annual maintenance. So the FFU System, delivered with EC-fans from Nicotra||Gebhardt and commissioned by vbk technology in 2013 was checked was well.

Uniquom - worldwide

From now on one of the greatest manufacturers of capacitor foil controls his ebmpapst EC-fans withModbus- and ebmBUS- Interface by anuniquom handheld.

Because of the Slovakian branch ordered directly we are glad about the 23rd country-link in ourinteractive customer map.

Compressor Racks for Blast Freezers

Together with our Partner KälteConceptwe 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 PLCS7-1500 CPU programmed with TIA-portal.

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
