Oxeo EcoPrevent PG

The next generation in fire prevention

Ad­vant­ages at a glance

The new Minimax Oxeo Eco­Prevent PG fire pre­ven­tion sys­tem is based on state-of-the-art PSA (Pres­sure Swing Ad­sorp­tion) tech­no­logy for ni­tro­gen (N2) gen­er­a­tion and con­sumes less com­pressed air and en­ergy than pre­vi­ously used PSA and mem­brane sys­tems.

Thanks to par­tic­u­larly ef­fi­cient com­pon­ents, the sys­tem al­ways op­er­ates at low pres­sure levels of 6 to 9 bar(g). It has a sep­ar­ate com­pressed air source or can be sup­plied via a cus­tomer's ex­ist­ing com­pressed air net­work.

      Op­er­at­ing prin­ciple
      • The PSA ni­tro­gen gen­er­a­tion sys­tem works on the pres­sure swing prin­ciple. Tanks filled with car­bon gran­ules real­ize the sep­ar­a­tion of oxy­gen and thus the re­duc­tion of the oxy­gen con­tent in the air. The gran­ules con­sist of spe­cially treated ac­tiv­ated car­bon, which en­ables the sep­ar­a­tion of oxy­gen and ni­tro­gen.
      • In con­trast to the Oxeo Eco­Prevent VG vari­ant, the PG vari­ant uses a sep­ar­ate com­pressed air source that op­er­ates at a pres­sure level of 6 to 9 bar(g) as well as suit­able com­pressed air treat­ment. The com­pressed am­bi­ent air is fed into an ad­sorp­tion tank. This con­tains car­bon gran­ules that re­tain the smal­ler oxy­gen mo­lecules in their pores. The ni­tro­gen can thus flow past and is thus sep­ar­ated from the oxy­gen. A cycle lasts about 60 seconds and in­cludes the sep­ar­a­tion of ni­tro­gen in one tank (ad­sorp­tion) and the re­moval of the bound oxy­gen in a second tank (de­sorp­tion). Since this pro­cess is re­peated con­tinu­ously in al­tern­a­tion, ni­tro­gen is per­man­ently avail­able for sup­ply­ing the pro­tec­ted area.
