EN 12845 classifies schools as Ordinary Hazard 1 (OH I) which requires water flow rates of up to 540 litres per minute at a pressure of 1.7 BAR. A flow rate that most water companies are reluctant to supply and WILL NOT guarantee. To ensure a reliable supply, the alternative is large water storage tanks of up to 55,000 litres in capacity and a diesel pump house. A substantial sized area is required for the tank site and comes at a considerable cost when taking into account the ground works and preparation of a suitably engineered base.

If the provision of a large water supply or the space for the tank with associated costs are an issue then the Minimax EconAqua Low Pressure Water Mist System is the solution. Unlike other low pressure water mist systems EconAqua is the only complete system that has been stringently tested and certificated to LH, OHI and OHII for land based applications by VdS (The German national test laboratories).  Other low pressure water mist systems have at best, tested and certified the head component only to I.M.O standards (International Maritime Organisation) and not the system as a whole.
