Description

CEMENT REMOVER is a liquid acid type product that effectively removes cement from cement transportation vehicles reservoirs, for the transfer of cement to vessels, machinery, pumps, wooden floors etc.

CEMENT REMOVER contains inhibitors and surface-active agents to protect sound metal surfaces giving a more efficient reaction with the cement.

Application

It is used as is or diluted with water in a concentration of 10 – 40 % in water depending on the glued amount of cement.  It is effective either cold or warm.  For best results it is recommended to be used in a temperature up to 60^o C.

The re-circulation helps with the dissolution of the cement.  The time needed to act is between 15 – 30 minutes depending on the amount of cement.     

For the calculation of the necessary amount of the product needed you must keep in mind that about 1 kilo of the product dissolves 1 kilo of cement.

Apply by any conventional method such as hard brush, mop, sponge, spray, etc. Allow the product to act from 15 – 30 minutes and wash thoroughly by applying high-pressure water.          

During the reaction of the product with cement bubbles are created, this is an indication that the product is still active.  When the bubbling stops it is an indication that the cement is completely dissolved or the product is neutralized.  Afterwards check the system and if there are still traces of concrete add some more of the product and repeat the above procedure.

Description

DESCALER is a liquid acid type product that effectively removes calcium carbonate and magnesium hydrate scales from heat exchangers, boilers, evaporators and other types of water systems.

It contains inhibitors and surface-active agents to protect sound metal surfaces giving more efficient reaction with the scale deposits.

When dissolved in water, its ingredients became chemically active, removing rapidly light scales and rust without appreciable action on the sound metal beneath. Through chemical reaction the scales are converted into highly soluble salts that are easily flushed away.

Generally a single treatment with DESCALER restores full system efficiency. Subsecquent treatments periodically will prevent the heavy scale incrustations and rust deposits that inevitably lead to serious impairmant of system efficiency, costly downtime and expensive repairs.

DESCALER is not recommended for use on aluminum and its alloys.

Application

DESCALER is used in a concentration 10 % in the water. The concentration varies, depending on the nature and the quantity of the scale.

Cold solutions work very satisfactorily. However, heating speed its action, with greatest efficiency obtained at 160 ^oF.

To strengthen solutions weakened through usage, simply add more DESCALER to restore solution to desired concentration.

Add DESCALER directly to the water in the system.

Circulate solution, hot or cold, until inspection shows system is free of scales.

Depending on the condition of the system a circulation of 12-36 hours is sufficient.

When system runs clean, flush with water and neutralize residual acid with our product KEM-NUTRO or ALKALINITY CONTROL in a concentration of 1,5 % - 3 % solution.

Approvals

DESCALER is approved by the Greek Chemical State Laboratory with approval No. 13631/0/2009.

Description

SCALE OFF-LS-30 is a liquid acid type product that effectively removes rust, calcium carbonate and magnesium hydrate scales from heat exchangers, boilers, evaporators, closed and open re-circulating cooling systems and all other types of water systems.

It is ideal for cleaning engine cooling systems, for car engines and truck engines.

It contains inhibitors and surface-active agents to protect sound metal surfaces giving more efficient reaction with the scale deposits.

SCALE OFF-LS-30 is the only product, which is safe on aluminum and its alloys.

When different metals exist in the system with aluminum, we suggest the use of SCALE OFF-LS-30 because any other chemical will destroy aluminum.

Application

SCALE OFF-LS-30 is normally used in a concentration of 10-20 % in water.

The concentration varies, depending on the nature and the quantity of the scale.

Cold solutions work satisfactorily. However, heating speeds its action, with greatest efficiency obtained at 70 ^oC.

When the temperature exceeds 50 ^oC probably the aluminum and aluminum alloys will be slightly affected.

To strengthen solutions weakened through usage, simply add more SCALE OFF-LS-30 to restore solution to desired concentration.

Add SCALE OFF-LS-30 directly to the water in the system.

Circulate solution, hot or cold, until inspection shows system is free of scales.

Depending on the condition of the system circulation for 1-24 hours is sufficient.

For car and truck engines, 30 minutes up to 1 hour is sufficient depending on the condition of the system and the amount of scale and rust.

When system runs clean, flush with water and neutralize residual acid with our product KEM-NUTRO-S in a concentration of 1,5 % - 3 % solution (refer to PDS for KEM-NUTRO-S).

Description

SCALE OFF-S is a powder acid type product that effectively removes calcium carbonate and magnesium hydrate scale from heat exchangers, boilers, evaporators and other types of water systems.

It contains inhibitors and surface-active agents to protect sound metal surfaces and give more efficient reaction with the scale deposits.

When dissolved in water its ingredients become chemically active, rapidly removing light scale and rust without appreciable action on the sound metal beneath. Through chemical reaction the scale is converted into highly soluble salts that are easily flushed away.

Generally a single treatment will restore full system efficiency. Subsequent treatments periodically will prevent the heavy scale incrustations and rust deposits that inevitably lead to serious impairment of system efficiency, costly downtime and expensive repairs.

Use Instructions

SCALE OFF-S is used in a concentration 10 % in the water. The concentration varies, depending on the nature and the quantity of the scale.

Cold solutions work very satisfactorily. However, heating does speed its action, with greatest efficiency obtained at 160 oF.

To strengthen solutions weakened through usage, simply add more SCALE OFF-S to restore solution to desired concentration.

Add SCALE OFF-S directly to the water in the system.

Circulate solution, hot or cold, until inspection shows system is free of scale. If solution requires bolstering in strength, simply add SCALE OFF-S directly to the solution.

When system runs clean, flush with water and neutralize residual acid with our product K-NUTRO or ALKALINITY CONTROL  in a concentration of 1,5 - 3 % solution.

Description

RUST REMOVER is a de-oxidizing liquid detergent containing phosphoric acid and non - ionic surfactants used for rust removal and surface brightener.

Application

RUST REMOVER is used for the removal of light rust from iron and brightening of surfaces, removing of tarnish from brass, copper aluminum, as a protective pre- treatment prior to painting, removal of flush rust from mild steel cargo lines and tanks and finally as a cleaner from rust stains from painted surfaces, glass, porcelain etc.

RUST REMOVER leaves surfaces free of rust tarnish, provides protection on ferrous surfaces, forms a protective coating on steel surfaces, is biodegradable, non flammable and safe for painted surfaces.

Usage

RUST REMOVER can be used in full strength or diluted with water in a ratio of 1:4 to 1:6, depending on the soiled condition of the surface to be cleaned. Can be used by immersion, or spray and then rinse with water. Do not use RUST REMOVER on zinc, tin and galvanized surfaces.

Description

KEM – NUTRO is an alkaline compound suitable for passivated ferrous

surfaces and preventing further oxidation.

Application

KEM – NUTRO is used after treating ferrous surfaces with acidic solutions such as our products, SCALE OFF, DESCALER, SCALE OFF – S, etc.

Usage

KEM – NUTRO can be applied by spray, mop or immersion, diluted in water in a proportion of 5 – 10% when designated to neutralize ferrous surfaces from acidic solutions.

KEM-NUTRO is diluted with water in a proportion of 1.5 – 3% when it used after acid cleaning to neutralize and passivate boilers, cooling systems, evaporators, etc.

Circulate the solution hot or cold for 2-3 hours empty the system and flush out with water.

If the solution is hot 50-60^oC the results are better.
