SHENHO 26
SCALE REMOVING AGENT
SHENHO 26 SCALE REMOVING AGENT
✻ Strong solution for scale and rust.
✻ Suitable for the equipment of stainless steel, copper and copper alloy.
✻ Suitable for rinsing heat exchanger, cooler, condenser and boiler.
✻ Easy and safe to use.
PRINCIPAL USE：
The impurities contain in that water of cooling system will deposit when used for a period of time; such deposited impurities will adhere to condenser, heat exchanger and pipeline to form scale. This will reduce the efficiency of heat exchanger, waste energy, and even cause the serious effect that air conditioner breaks off to reduce the production capacity of factory.
SHENHO 26 is specially designed to solve and clean the formed scale in the shortest time and recover the efficiency of condenser and heat exchanger. SHENHO 26 contains the special surfactant and corrosion inhibitor to soften and wet the scale, and expedite the solution. Furthermore, even use SHENHO 26 for long-time rinsing, it definitely will not corrode the metals such as copper, iron and copper alloy…etc. The unique rinsing character cannot only solve the scale thoroughly but will also release the oxide on the surface of metals, such as rust and verdigris.
GENERAL DESCRIPTION：
Appearance ………………………… Clear Yellow Liquid
Specific Gravity …………………… 1.10±0.05
Rinsability …………………………… Excellent
Solubility …………………………… Completely solve with water
DOSAGE：
In general case, it needs 1/4~1/5 amount based on the water holding capacity of the equipment. Correct dosage will be based on that amount of the scale adhered.

APPLICATION：
A.Rinsing for all system of air condition：
- Drain off the water inside the tray of cooling tower completely, and pour appropriate amount of SHENHO 26 into the tray.
- Start the circulating pump of cooling water for 1~3 minutes. Upon a significant amount of foam has returned to the cooling tower, close the power of pump for 5-10 minutes and begin the rinsing of scale inside the condenser.（Repeat the rinsing action for 2-3 times.）
- Upon the completion of rinsing, start the pump again to activate the agent circulating to rinse all system sequentially for 1~3 hours to remove scale entirely.
- Once the removal effect has got approval, drain off the black cleaning agent（chemicals）completely. Fill up clean water into the tray and start the pump to flush all system for 5~10 minutes, and then drain off entirely.
- Flush and replace water for 2 times repeatedly to finish scale removal procedure.
- Fill up the water to activate the air conditioner.（If necessary, might keep the cooling water flow over for a period of time till the water is entirely clear.）
B.Rinsing for air conditioner and heat exchanger：
- Prepare temporary circulating pump and pipeline as above figure in advance.
- Mix appropriate amount of water and SHENHO 26 as the cleaning agent, and then pour into the plastic tank. Use the temporary pump to fill in the cleaning agent from the pipeline beneath, and open the upper vent valve. As soon as the cleaning agent has flowed over from vent valve, close vent valve immediately and make the agent circulate for 1~3 hours.（In the duration of circulation and rinsing, use “test kit” to check the concentration of cleaning agent more than 3 times at least.）
- Once the removal effect has got approval, drain off the cleaning agent completely.
- Pour clean water and flush till the water is entirely clear.
- Discharge the temporary pipeline to return its original status.
NOTE：
KEEP OUT OF REACH OF CHILDREN. SHENHO 26 may cause irritation to skin and eyes. In case of contact, flush with water and get medical attention immediately.
