Berlin, June 5, 2012. Leading RTLS and WSN provider nanotron Technologies has supported civil and industrial petrochemical expert Wolftank Systems with its innovative chirp technology. By integrating nanotron’s unique chirp technology, the Wolftank Systems product, SEFI6, enables wireless data transfer in the most hard to reach and hazardous conditions typical of the petroleum and chemical industry. SEFI6 securely transmits data where conventional wireless transmission devices are unable to operate. Wolftank Systems utilises SEFI6 to wirelessly monitor critical parameters of plants as well as above ground and underground storage tanks.

SFEI6 makes wireless monitoring of critical parameters possible for ATEX regulated environments. This includes underground facilities, massive constructions and facilities behind thick security doors or inside chambers covered with metal or cast iron. The technology even operates through electrically shielding barriers and under conditions where additional soil, groundwater or reinforced concrete may act as “faraday cage” like barrier to wireless transmissions. Even under such awkward conditions, the wireless sensor network remains highly reliable.

SEFI6 comprises of remote sensor units, repeater units (if necessary) and a control unit with network connection. Wireless connectivity simplifies the installation of sensors in potentially explosive and strictly regulated ex-zones; eliminating the costly and time-consuming digging and cable setting – reducing costs and saving time. Also, further security measures such as galvanic barriers or shielding are no longer required. Thus, nanotron’s technology offers improved reliability while reducing the total cost of ownership.


Wolftank Systems CEO, Dr. Peter Werth, explains, “nanotron’s chirp spread spectrum radio technology ensures stable data connection – even under the most difficult conditions. This allows us to take an entirely new approach to wireless monitoring of critical parameters in ATEX regulated environments. We have installed our SEFI6 product in more than 50 fuel storage plants since April 2011 for uninterrupted operation 24 hours a day, 7 days a week.”

nanotron Chief Executive Officer, Dr. Jens Albers, adds, “We are happy to see our technology enter further challenging application environments such as the petroleum and chemical industry. With SFI6, Wolftank Systems has achieved full ATEX 94/9/CE certification, to conform to the RTTE directive. This shows that our technology meets the highest standards.”

nanotron and Wolftank Systems successfully showcased their product at the IDTechEx in May in Berlin.
