MODBus-RTU-DCI vs. MODBus-RTU

to stay deliverable, on of our cleanroom customers decided somewhat unsuspectingly to apply the DCI-Variation, instead of the normal MODBus-RTU variation of his EC- FFU s from ebmpapst. As consequence some single commands of the "Install fan"- order package of our FFU-control device uniqunet ended in nowhere, that the installation process could not be accomplished. Even if not caused by us a software adaption of the uniqunet control device seemed to be the most simplest solution.

Seven days, incl. basic investigation, program adaption, test, verification and application at customers’ side is more than presentable, as we do think.

Cleanrooms – Modernization of an ebmpapst Control

Following a recommendation by ebmpapst a big building automation company from Leipzig requested support for renewing a FFU control system of EC-FFUs, each with an ebmpast-drive, in Erfurt.

With pleasure we provided, besides to some advices, a handheld tool for the EX-Fans free of charge to check the operation of the system. As only the terminal-box has been changed to one with ebmBUS interface, it was not entirely clear if a surprise awaited the costumer.

Yesterday evening we received the enjoyable feedback, anything went perfect and that easy that they even had enough time to address the FFUs already correctly. So there are no technical reasons that speak against the usage of 3 EC-FFU Control devices.

EC Motor Control for US-Cleanrooms

By mid of March a US-American OEM-customer placed an order for controllers for their EC fans. Hand programming tools as well as EC Control devices for the fixed installation were ordered to use the ec fan advantages of their ec fan technology in cleanroom applications.

EC Motor Control device production

It is for us more than a matter of decency, even in difficult times, to match costumers’ wishes in terms of delivery date. Due to the outstanding commitment of our employees we achieved to create a time reserve the American duty know “to use”.

FFU Commissioning at Bielefeld University

Last Tuesday we realized the final commissioning of an FFU-appliance at the Institute of Experimental Physics at Bielefeld University.

  • Institute of Experimental Physics at Bielefeld University
  • FFU's (Filter Fan units) with EC fan technology

In total 13 FFUs of different sizes, equipped with EC fan technology, show up their advantages. They are separated to 4 groups controlled by 2 different EC-fan control devices from 2 different generations.

FFU Service Jena

Jena in Thuringia is home of many high tech companies. One of them, specialist for high temperature superconductor, extended his cleanroom capacity right now. The new FFUs, all of them of the new high efficient product line from NICOTRA Gebhardt, needed to be connected to an existing EC-Fan control device.

The good news is, that FFU groups can be built out of different RS485 BUS lines not matter if they are existing EC FFUs or new ones.

Finally the way home brought some childhood memories, “counting tunnels” in the train of the lower train way from Gera to Plauen.
