Torrium® Delivers Flow-On Benefits:

• It’s not easy living with water pressure problems. Poor or inconsistent water pressure can result in a broad range of problems like poor 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 System Controller 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-day problems. It also means there’s far less installation and maintenance issues. This unique ability to respond to changing circumstances ensures a steady, reliable flow of water is virtually guaranteed day after day, year after year.
• CONSTANT FLOW
  With a Torrium® system you’ll hardly notice the pump start. Better still while you are using water, like in the shower, the pump doesn’t cycle, overcoming those annoying temperature and pressure changes.
• ADAPTIVE PRESSURE SWITCH
  Torrium® measures the system pressure and adapts the system cut-in pressure according to circumstances, thus providing a more reliable system with improved comfort and convenience.
• LOSS OF PRIME PROTECTION
  If you run out of water, the last thing you need is a pump that continues to run without water. The Torrium® detects a loss of water supply (prime) and shuts the systems down. What’s more it will Auto retry to re-establish prime if possible and Auto-restart on water flow return.
• AUTO RETRY
  Auto retry in Torrium® allows the system to reset itself after a loss of prime, thus helping reduce system downtime.
• SIMPLIFIED FAULT FINDING
  Torrium® is equipped with a status indicator to make system fault finding quicker and more accurate. Torrium® can tell you if you have a slow filling toilet cistern, a loss of prime, a slow leak, low supply voltage, water over-temperature, even if someone has tried to bypass the Torrium®!
• LOW PRESSURE DROP
  Torrium® has been designed to get the most from your pump, including pressure. The Torrium® has a very low water pressure loss through it, so that you can get the best performance at your outlets.
