Descaling Solution For Solar Water Heater

Water contains various metallic salts in suspension. These metallic salts get accumulated inside pipelines, tubes, etc. in the form of scales over a period of time. These scales must be removed periodically in order to restore the efficiency of system, reduce heating time and attain the required temperature.

Scalgun Saf Liquid (SSL) has been formulated mainly for descaling Solar Water Heating System. It is an inhibited acidic composition containing surface active agents and cleaning agents to effectively dissolve and remove all water scale deposits from Copper, Brass, M.S., S.S. and Aluminium tubes, Pipelines and Vessels. Descaling with SCALGUN SAF LIQUID is safe, simple and economical.

Descaling Procedure:

Descaling of Solar Plate Tubes alongwith Storage Tank by Circulation Method:

1. Prepare a 10% solution of SCALGUN SAF LIQUID (SSL) v/v (volume by volume) with water in a 50 to 100 litres capacity open top circulating tank (To prepare 100 litres of SSL solution – add 10 litres SSL to 90 litres water). Tank must be made of either Plastic, S.S. or FRP/PVC lined M.S. tank

2. Connect the outlet of this open top circulating tank by a rubber/plastic hose to the inlet of a 1 or 2 HP S.S./Plastic pump. The outlet of pump should be connected by hose to the drain valve of solar plate. Connect the outlet of the storage tank by hose back to the circulating tank

3. Start the pump and completely fill the system with SSL solution by circulating the same for 3-4 hours preferably at 45°C

4. Discard SSL solution and then completely flush the system with plenty of water by circulation till the pH of water reaches 6-7

Descaling of Solar Plate Tubes only without Storage Tank by CIRCULATION Method:

1. Same as 1 (a) above
2. Same as 1 (b) above – with storage tank disconnected. The return hose pipe to the circulating tank should be connected at union outlet
3. Same as 1 (c) - without filling storage tank
4. Same as 1 (d)

a 5% - 10% solution of Scalgun-WS with water can be made and then either circulated or left overnight at ambient temperature to remove all water scale deposits without attacking the base metals. Scalgun additive at 1% may be added separately if required to remove for silica scales. After descaling, flush with water and passivate with 1% solution of asfofix-p with water.

Scalgun-WS is available in standard packing of 35 kgs.
