Poor or inconsistent water pressure can result in a broad range of problems likepoor showers or slow filling dishwashers etc. That’s why Davey invented the extremely clever, Torrium® Pressure System Controller.Five years in the making and thousands of hours of world wide, in-the-field testing have culminated in a Pressure SystemController that can actually think for itself.The Torrium® can automatically adapt to changing conditions…because it has an in-built ‘brain’ that can out-smart every-dayproblems. It also means there’s far less installation and maintenance issues. This unique ability to respond to changingcircumstances ensures a steady, reliable flow of water is virtually guaranteed day after day, year after year.T H E T O R R I U M ® D E L I V E R S F L O W - O N B E N E F I T SC O N S TA N T F L O WL O S S O F P R I M E P R O T E C T I O NWith a Torrium® system you’ll hardly notice the pump start.Better still while you are using water, like in the shower, thepump doesn’t cycle, overcoming those annoying temperatureand pressure changes.If you run out of water, the last thing you need is a pump that continues to run without water. The Torrium® detects aloss of water supply (prime) and shuts the systems down.What’s more it will Auto retry to re-establish prime if possibleand Auto-restart on water flow return.A D A P T I V E P R E S S U R E S W I T C HS I M P L I F I E D FA U LT F I N D I N GTorrium® measures the system pressure and adapts the systemcut-in pressure according to circumstances, thus providing amore reliable system with improved comfort and convenience.Torrium® is equipped with a status indicator to make systemfault finding quicker and more accurate. Torrium® can tell youif you have a slow filling toilet cistern, a loss of prime, a slowleak, low supply voltage, water over-temperature, even ifsomeone has tried to bypass the Torrium®A U T O R E T R YL O W P R E S S U R E D R O PAuto retry in Torrium® allows the system to reset itself after aloss of prime, thus helping reduce system downtime.Torrium® has been designed to get the most from your pump,including pressure. The Torrium® has a very low water pressureloss through it, so that you can get the best performance atyour outlets.
