Ivar Polifemo Extra polyphosphate and spherical silicate doser

IVAR POLIFEMO EXTRA DOSER OF POLYPHOSPHATES AND SILICATES IN BALLS

The polyphosphate and silicate doser is a device aimed at protecting boilers, water heaters, washing machines and dishwashers from the formation of limescale and incrustations which compromise their correct use and duration. When a polyphosphate and silicate dispenser is installed on the delivery pipes of a boiler (or other devices crossed by water), its slow release of polyphosphates and silicates creates a film on the pipes which protects them from the formation of limescale and therefore from corrosion ; this is particularly useful if the water is hard or very hard . It is therefore strongly advisable to install it on all household devices that use water.

The new IVAR POLIFEMO EXTRA polyphosphate and silicate dispenser is a device without moving parts which releases a solution saturated with food polyphosphates and silicates into the domestic cold water. The dosing of the substances is proportional to the water flow that passes through the device and takes place via the suction pipe which takes the right amount of saturated solution from the cup. The dosing principle is based on the pressure differences created in the device when a certain flow of water passes through it.

Thanks to the polyphosphates and silicates, and the presence of the stainless steel safety filter integrated in the device, POLIFEMO EXTRA performs three different functions :

1. Protects from limescale

2. Protects against corrosion

3. Filter out impurities.

The slow dosage of phosphates of POLIFEMO EXTRA carries out the anti-limescale action by preventing the precipitation of calcium and magnesium carbonate; the dosage of silicates performs the protective function against corrosion . Thanks to the particular shape of POLIFEMO EXTRA, the water is forced to pass through its glass, in any position it is installed, therefore the filtering action is always guaranteed . In any case, vertical installation is preferable for correct visualization of the charge level. POLIFEMO EXTRA further simplifies the monitoring of the consumption of the polyphosphate spheres in the glass: if the eye closes, i.e. if the level indicator has reached the base of the glass, it is time to top up.

The POLIFEMO EXTRA doser is equipped with a special by-pass valve to allow normal operation of the system even in the phase of refilling and cleaning the device. It can be installed to protect boilers, water heaters, dishwashers and washing machines.

TECHNICAL FEATURES

Body and ring nut of the POLIFEMO EXTRA silicate and polyphosphate dispenser are in chromed brass, the cup in Grilamid TR, the filter in PP, the gasket in EPDM. It can withstand an operating pressure of up to 10 bar; the duration of a recharge is approximately 6 months considering connecting the device to a boiler used by 4 people which delivers hot water at 42°C.

POLIFEMO EXTRA is already complete with a spare cartridge, the connection kit and the key to assemble and disassemble the cartridge. The spare cartridges, cod. 520213, can be purchased separately. Volume of treated water with one refill: approx. 100 m³. Maximum flow rate: 30 l/min (with ΔP equal to 0.5 bar). Connections: 1/2 F. Glass: extra large.

To be installed vertically or horizontally on the cold water pipe upstream of the domestic hot water producer (boiler, water heater, etc.) or upstream of the appliance to be protected (washing machine, dishwasher).

NB : The use of polyphosphates for limescale prevention is satisfactory on medium or hard water, up to 30°f. Beyond this degree of hardness, it is recommended to install a softener to protect the entire system.

It is also advisable to pay attention to the distribution temperature of the domestic hot water: beyond 60°C in the treated water, there may be phenomena of precipitation of calcium and magnesium carbonates (limestone).
