As previously announced, the Hürner-Funken, Hürner-Funken Systemtechnik and Monsun 
merged in Hürner Luft- und Umwelttechnik GmbH (HLU) at this year.

HLU interlinks future-oriented air technology with sustainable environmental technology. The merger of the companies formerly part of the Hürner-Funken Group complements the extensive fan and component knowledge of Hürner-Funken GmbH, the Monsun GmbH with project and service expertise as well as the broad technical know-how of Hürner-Funken Systemtechnik GmbH.

In a first step, Hürner-Funken GmbH will be renamed Hürner Luft- und Umwelttechnik GmbH as of January 01, 2018. During this year, the Monsun and the Hürner-Funken Systemtechnik will be integrated into the HLU. Until then, they continue to operate independently under the name HLU Monsun GmbH and HLU Systemtechnik GmbH.

For you, apart from the company name, nothing changes in the usual good cooperation. You will continue to have access to the previously known employees. Your contact persons are available under the telephone numbers and e-mail addresses as usual in all areas.

We look forward to further joint projects and are always available to answer questions.
