TECO Hardness Control Liquid

TECO Hardness Control Liquid

TECO Hardness Control Liquid

Liquid boiler water conditioner.


Features & Benefits

• Quick dissolving, fast acting phosphate-based compound

• Reduces hardness in boiler water and prevents formation of calcium and magnesium scale

• Converts hardness salts to non-adherent sludge that can be removed by blowdown

• Easy to mix and easy to dose

• Simple to test and simple to control level of treatment

• Can be used on all types of boilers and all pressures

• Maintains the boilers’ optimum phosphate levels to avoid scale and corrosion

• Stops the boiler from scaling and maintains the system in optimal condition

• Economical to use

• Reduces the need for chemical cleaning


Product Description

TECO HARDNESS CONTROL LIQUID is a highly efficient phosphate-based liquid, designed to stop

calcium ions from adhering to the metal surfaces and condition them for blowdown. This product is

easy to use and easy to dose.



TECO HARDNESS CONTROL LIQUID is added to the boiler water to maintain an optimum phosphate

level. Under these conditions, calcium and magnesium hardness salts cannot form and the precipitate

can be removed by blowdown. Please note: This product is part of a TECO CHEMICALS coordinated

treatment and should not be used with a combined treatment.


Direction for use

The dosage of the product is 200 ml/l. For optimum results, the product should be dosed directly into the

boiler via a by-pass pot feeder installed in the boiler feed line.

Control Limits

The recommended control limits are:

Hardness: Zero

Phosphate: 20 - 40 ppm (LP boiler)

Phosphate: 10 - 30 ppm (HP boiler)

Analysis is carried out using TECO CHEMICALS TEST KIT PHOSPHATE.


Standard Packing

TECO HARDNESS CONTROL LIQUID is usually available in plastic cans of 25 l.
