Anti scale dosing units for boilers, with level alarm

Zerocal does not require power supply and is fitted with a sound and visual signal system warning you when it is time to refill the anti scale liquid (yellow led) and when it is time to replace the battery (red led).
The ergonomic shape and the adjustable bidirectional connections make installation fast and easy.
Thanks to the special Dima fittings Zerocal Dima can be easily installed in the small spaces between the wall and the boiler.
Each pack includes a Zerocal DOSE refill.
Material for pump and tank: POM/ PE.To refill the anti scale product it is not necessary to close water supply; it is enough to unscrew the tank, pour in Zerocal DOSE and place the tank back in.

Anti scale and anti corrosion proportional dosing units

DOSAPHOS 200, 250 and DIMA are anti scale and anti corrosion dosing units for boilers, water heaters, washing machines and dishwashers.
The operation is based on the automatic and proportional dosing of the Gelphos product, with chelating and sequestering action, able to:

• prevent calcium carbonate deposits (no scale)
• form a protection film on the internal surface of pipes (no corrosion).

Thanks to the adjustable connection flange between the venturi system and the dosing body, Dosaphos units can be installed on horizontal and vertical pipes.
Dosaphos units can be easily installed in the small spaces between the wall and the boiler thanks to the special Dima fittings.
Dosaphos 250 and Dosaphos Dima are fitted with the Acquastop device, which avoids to build the cut-out bypass of the system and allows to refill the product easily without closing water supply.
Each pack includes a Gelphos Rapid refill.
Material: head in brass, housing in SAN.

Analog constant metering pumps

Analog constant metering pumps are fitted with:

• foot filter
• suction and delivery connections
• injection connection
• suction and delivery hoses
• level probe (for PCS models only)

The SE version is assembled on a 100 l. tank.
DOSPRO PC and PCS constant metering pumps are suitable for treating water with a flow rate which is constant in time.
They can also be installed in parallel to booster pumps (with surge tanks use DOSPRO PPI).
Dosage can be adjusted from 0 to 100% of the maximum flow rate of the pump.
Pumps can be used for disinfection, anti scale and anti corrosion treatments, conditioning for potable and technical use.

 

Digital constant - proportional metering pumps

Digital constant-proportional metering pumps are fitted with:

• foot filter
• suction and delivery connections
• injection connection
• suction and delivery hoses
• level probe
• water meter with pulse output (for PPI models only)

CWG_DOS/PROP and PPI metering pumps, with constant and/or constant/proportional dosing, are able to dose the chemical according the water flow thanks to the water meter with pulse output (standard in PPI model and accessory for PP model).
Dosage can be adjusted in the different modes below:Constant Pump doses with constant frequency according to the values set during programming.
Divide The pulses given by a meter connected to the pump are divided by the value set during programming.
Multiply The pulses given by a meter connected to the pump are multiplied by the value set during programming.
PPM The pulses given by a meter connected to the pump determine the dosage according to the value of mg/l set.
Batch The pulse given by an external contact starts the dosing.
Pump can be programmed to dose a specific quantity.
Volt The voltage supplied to the pump determines the proportional dosing according to the “min” and “max” values set during programming.
mA The power supplied to the pump determines the proportional dosing according to the “min” and “max” values set during programming.
