ROCHEM DESCALEX POWDER has been designed for rapid descaling of waterside deposits. It is a nonvolatile non-hygroscopic odourless powder which is compounded of dry acid inhibitors and wetting agents. DESCALEX POWDER has an unlimited shelf life and is completely soluble in water. It contains no chlorides has low corrosion rates and will not stress-crack stainless steel. USAGE ROCHEM DESCALEX POWDER dissolves water scale and rust deposits in heat exchangers air conditioning plants intercoolers and similar equipment. It is also effective in descaling oil wells and industrial water wells. ADVANTAGES 1. ROCHEM DESCALEX POWDER reduces maintenance costs and lowers labor requirements due to faster more efficient regularly scheduled cleaning. 2. ROCHEM DESCALEX POWDER reduces the need of extensive dismantling while cleaning inaccessible areas such as small tubes short bends and irregular surfaces. 3. ROCHEM DESCALEX POWDER reduces the dangers and handling problems of liquid acids with no sacrifice to efficiency. APPLICATION ROCHEM DESCALEX POWDER is normally used as a 5% water solution (50 Kilos of DESCALEX POWDER per metric ton of water) which is equivalent to a 10% solution of ROCHEM Descaling Liquid. DESCALEX POWDER should be dissolved in warm water unless agitation is employed with cold water. The equipment being cleaned is filled with the 5% DESCALEX POWDER solution and agitated with air or steam but preferably with a pump capable of providing good circulation. Circulation time required will vary from a few hours to 24 hours. For maximum results the solution temperature should be held between 60 C (140 F) and 77 C (170 F). After completing the cleaning the equipment should be drained and then neutralized by introducing ROCHEM ALKLEEN in 1% water solution (10 Kilos of ALKLEEN per metric ton of water). Fill the equipment with the ALKLEEN solution and circulate it through the system for at least an hour. The pH value of the solution should stay above 8. If necessary add more ALKLEEN until satisfactory pH is maintained. Drain the ALKLEEN solution then flush the system twice with fresh water. By its sequestering action the ALKLEEN solution will prevent redeposition of undissolved solids on the metal surfaces and permit thorough removal by blow-down.

ROCHEM DESCALING LIQUID has been developed for rapid and thorough cleaning of heat transfer surfaces by chemically removing rust and water scale. It is a non-volatile liquid which is compounded from liquid acid inhibitors and wetting agents. ROCHEM DESCALING LIQUID is inhibited against attack on all metals except aluminium zinc and magnesium. It has unlimited shelf-life. ROCHEM DESCALING is also very useful for removal of Lime coating from cargo holds. GENERAL SPECIFICATIONS Appearance : Fuming Liquid Colour : Reddish Brown pH : Acidic Specific Gravity : 1.14 to 1.16 Oxydising properties: : None Solubility in water : Soluble in water USAGE ROCHEM DESCALING LIQUID can be used effectively for cleaning nearly every type of equipment subject to rust and scale buildup. By lowering labour requirements and reducing equipment down time ROCHEM DESCALING LIQUID has proven itself to be efficient and highly economical in cleaning of the following equipment and auxilaries ; fire-tube and water-tube boilers condensers superheaters economisers evaporators steam and water lines distillery equipment air conditioning units water jackets of internal combustion engines cooling and piping systems etc. APPLICATION The cleaning method and time required depend on the character and thickness of the rust and scale size of equipment to be cleaned availability of circulation equipment concentration of ROCHEM DESCALING LIQUID temperature of cleaning solution and presence of oily compounds covering rust and scale. Our ROCHEM service engineers are available to recommend exact procedures to be followed in each specific case. However the following is a general procedure that will prove effective in most cases: 1. The heat exchange equipment to be cleaned is filled with solution comprised of 1 to 3 litres of ROCHEM DESCALING LIQUID per 10 litres of water. This solution is circulated throughout the system for 8 to 16 hours. 2. The system is then flushed with fresh water which removes particulate matter and soluble salts. 3. Then a 1% water solution of ROCHEM ALKLEEN LIQUID is circulated throughout the system for at least an hour to neutralise the acid and to prevent redepositing undissolved soils on the metal surfaces by its sequestering action. pH of the solution should remain above 8. If it drops below add more ALKLEEN LIQUID. 4. Drain the ALKLEEN LIQUID solution and flush twice with fresh water.
