Recharging Dry Water Mist

Guest Sam

Recommended Posts

Hi there,


I am currently looking to purchase a dry water mist extinguisher (1L) however I am unsure if it can be recharged should it ever be needed and weather this could be done by myself or is it more specialist.

Hi Sam

The E-series dry water mist can be re-charged like any other extinguisher. You have to make sure that only de-ionised water is used, as it prevents bacteria growth and prevents the flow of any current if used on live electrical equipment. The refill should be carried out by a competent person, only, as high pressure is involved.

Ok thanks for the replies guys, is it exactly the same process as for a water extinguisher then ? With the same equipment (using de ionised water).


if so could somebody point me to where I could purchase this equipment ?

What is the pressure of the water mist extinguishers. Can the extinguisher cylinder be made from lighter materials like aramid for example?

Yes, Britannia's P50 range is Kevlar. They don't do a water mist because their ordinary water and foam extinguishers are safe for electrical fires up to 1000V in accordance with EN3

The main construction of the P50 is a HighDensity Polyethylene Aramid fibre Kevlar® type material weaved onto the body, it is strong and incredibly light. It is also also used in butane/propane gas bottles, towing ropes, bullet-proof vests, fire-proof gloves and many other products.
