Paper Tiger Serif  Suggested by Jef91 
Euphorigenic  Suggested by pilaster 

This logo seems to be used for a long long time, my guess would be that it's not a font, but that's just my opinion.

Logo here:

Otherwise you could do worse than fonts like:

Euphorigenic from Typodermic

which is similar in some of the letterforms.

Hi guys,

As a part of Jules Destroopers marketing team I'm afraid I'll have to disappoint you, since the font is a font especially made for the logo (so it also has a reduced number of characters). The font we use in our offline communication, however, is myriad pro. I hope this answer will be of some help to you guys.

Bert

The font I found resembling Jules Destrooper the most is Paper Tiger Serif Regular
