Description

OH-UPR is an automatic, upright low pressure water mist system ideal for non-automatic, fully enclosed garages, underground garages and such applications. The upright nozzle design in the system makes it possible to protect such applications with low water flows and water pressures, and at the same time protecting the nozzles themselves.

Tests and approvals

OH-UPR system has been successfully tested by an ISO17025 accredited test lab and 3. party accepted to the CEN/TS 14972:2016 watermist standard for non-automatic, fully enclosed garages. The test protocol is revised version of the VdS car park test protocol. Accordingly to the results the FIREKILL OH-UPR system can be used in non-automatic, fully enclosed garages, underground garages having up to 3m ceiling height.
