Tenders Are Invited For Rebuilding The Emsr Technology In The Gebläsehalle 2 (Gbh 2) On The Ka Mg-Neuwerk

To Ensure The Existing Process Air Supply For Biological Cleaning, A New Blower Hall (Gbh2) Is Being Built At The Kamg-Neuwerk. This Construction Measure Serves To Ensure The Operation Of The Existing Biological Cleaning. At The Same Time, This Measure Represents Redundancy In Order To Ensure That Biological Cleaning Is Maintained. The Nv Intends To Divide The Blower Hall Into Several Fire Compartments. The Maximum Final Configuration Is Eight Fans. Four Of These Turbo Compressors (Blowers) Are Installed In Two Rooms. It Is Also Planned To Set Up Two Emergency Power Systems (Neas), With The Associated Components, In Separate Rooms (Fire Protection Separation). The New Transformer Station 4 Is Planned To Supply The Systems And Structures With Electricity. Transformer Station 4, Including Transformers And Nshv, Will Be Built In Gbh 2. The Mv Switchgear And The Emergency Network Systems Are Being Built In A Separate Measure. Other Components Of The Project Include Six New Transformers, Two Low-Voltage Main Distribution Systems, Ups Systems And Active Harmonic Filters. The Fans Are Installed On Site And Are Already Equipped With Passive Harmonic Filters. The Active Filters Must Be Taken Into Account For The Remaining Harmonic Components Of The Frequency Converter-Controlled Drives (E.G. In The Pumping Station Of The Secondary Clarification And The Compact Stations Of The Aeration Tank). For The Automation Of The Blower Hall 2, A Total Of Two Automation Devices Are Provided Due To The Separation Of The Blower Hall Into Two Separate Areas. The Automation Devices Must Be Integrated Into The Existing Pcs 7. External Signals From Drives, Measurements, Nh Isolators, Etc. Are Only Integrated Into The Automation Technology Via Decentralized Peripheral Modules. Digital Modules With 16 Inputs/Outputs And Analogue Modules With 4 Inputs/Outputs Are Used. The Signal Integration Of The Process Engineering Components Into The Plc Takes Place Via Decentralized Input/Output Modules. The Integration Of Compact Systems (E.G. Nea) Into The Higher-Level Automation And Control Technology Level Takes Place In Hardware Via The Aforementioned Automation Devices. The Data Exchange Between The Plcs And The Nea Controls Is Based On Ethernet. The Two Automation Devices Must Each Be Equipped With A Control Panel For The Purpose Of Visualization And (Emergency) Operation. The Programming Services Are Awarded In A Separate Measure. The Electrical Equipment \/ Electrical Building Technology Of The Blower Hall 2 Includes The Installations For Lighting, Sockets, The Sub-Distributions As Well As The Cable And Laying Systems Required For This And Is Described Below. The Associated Building Technology Sub-Distributions Must Be Installed In The Lv Room Of The Ns Main Distributions (Nshv 1 \/ Nshv 2). The Sub-Distributions Of The Lighting And Sockets Are To Be Designed As Factory-Made, Sheet Steel Encapsulated Switchgear Using Fixed Installation Technology. The Lighting Of The Individual Areas Of The Blower Hall 2 (Gbh 2) Must Be Carried Out In Accordance With The Workplace Guidelines (Asr).
