Abstract
Systems and methods for filling and pressurizing a container with liquid suppressant and nitrogen gas. A pressurized receiving container of nitrogen gas is provided at a predetermined gas pressure and liquid suppressant is added to the pressurized receiving container. The predetermined gas pressure provides a sufficient amount of nitrogen to saturate the added liquid suppressant and provide an operative head space pressure within the receiving container without the need for mechanized mixing.
Claims13
A method of charging a container with firefighting liquid suppressant, the method comprises:
- providing a pressurized receiving container containing nitrogen gas at a predetermined pressure;
- and
- adding an amount of firefighting liquid suppressant to the receiving container.
The method of any one of the above claims, wherein adding the liquid suppressant includes transferring an amount of NOVEC™ 1230 extinguishing agent to the receiving container.
A system for filling and pressurizing a container with firefighting liquid suppressant, the system comprising:
- a receiving container defining an internal volume;
- a supply of nitrogen gas coupled to the receiving container for pressurizing the internal volume of the receiving container to an internal pressure;
- a supply of liquid suppressant;
- and
- a transfer pump coupled to the receiving container and the supply of liquid suppressant for transferring the liquid suppressant to the receiving container against the internal pressure to define a head space pressure.
