Application

For use with the HI-FOG® water mist fire protection system only. 

Description

The GPU pump is propelled by pressurized air or nitrogen. The pump is a piston-type pump with two double chambers. The gas is also used as an atomizing medium by feeding it into the system either directly (DF) or via water cylinder (WF). The feed water can be taken from a tank or from an external water supply. The pump starts when the propelling gas flows to the pump. A stand-by pressure of about 25 bar is maintained in the system by a pneumatic pump.


At each stroke, constant volumes of water and gas are discharged into the network. The operating pressure in the system is time-dependent: the pressure at the sprinklers gradually decreases from (80 ± 10) bar down to zero depending on the number of the gas cylinders.


The water and gas supply of each system is dimensioned to provide the total suppressant required typically for that application. The maximum flow of the pump unit is 120–150 L/minute initially. The discharge may be interrupted at any time by closing the shut-off valve.


The unit operation does not require any electrical power. Electrical power is applied for controlling, monitoring and signalling of the system performance as described in contract-specific requirements.


Features and benefits:

  • The HI-FOG GPU is self-contained, which means no external power source is needed for activating it. It operates on compressed air, which is used to produce fine water mist in the case of a fire. This makes the GPU a simple option for machinery spaces, for example.
  • The GPU consist of a gas-driven mechanical piston-type pump. It can take water from an external water system or from a water tank or cylinders. Therefore, it can be customized for various types of installation sites.
  • The size will be adapted to cover the protected space, so it will take up the smallest possible amount of space.
