Product information

Descaling of Boilers, Descaling of Diesel Engine Cooling Water Systems, Condensers, Evaporators, Calorifiers, Heat Exchangers:

Unitor™ has developed a 210 litres capacity cleaning unit designed among other for use with chemical acid solutions for cleaning boilers, calorifiers, heat exchangers and other types of equipment where rust and scale form.

Unitor™ Chemical Cleaning Unit: Product no. 737189

Notes regarding safety in descaling operations:

Unitor™ Descalex™ contains strong acids. Handle with care and pay special attention to Material Safety Data Sheet and / or Product Label. Use personal protection equipment as recommended.

Reaction products from acid components in descaling products may include gasses like carbon dioxide and hydrogen. Formation of hydrogen gas can be monitored with gas detection equipment on the vents. To avoid suffocation and potentially explosive atmosphere, gasses should be removed safely by purging system with water after draining the cleaning solution. Vent of system during descaling operations must be provided for same reason. Always use gas detection equipment to check that the atmosphere is safe before entering confined spaces for inspection after descaling operations. When circulating the descaling solution, always circulate with inlet at the bottom to avoid air pockets and potential entrapment of gaseous reaction products.

Features

  • Dry acid concentrated cleaner contains inhibitors to protect metals
  • Contains colour indicator to show the strength of the solution and anti-foam agent
  • Safe and easy handling and storage
  • Fast and effective scale remover
  • Removes scale from boilers and diesel engine cooling water systems
  • Removes scale and rust from condensers, evaporators, heat exchangers etc.

Benefits

  • Efficient, economical, safe

Specification

Approvals

Approved by the Norwegian National Institute of Public Health for cleaning of evaporators.

 

Directions for use

The most effective descaling is accomplished by circulation. In the case of small components, the soak method in an immersion bath can be used.

If the equipment to be cleaned is contaminated by oil, grease and sludge, then pre-cleaning with Unitor™ Seaclean Plus or Unitor™ Enviroclean is necessary.

Depending on the extent of scaling, use a solution of 2.5--10% Unitor™ Descalex™. The solution will have a red colour which disappear when the solution is neutralised. Whenever possible, the solution should be heated to 60°C.

Neutralised solutions can be reactivated by adding more Unitor™ Descalex™ until the red colour reappears. This should not be done more than twice.

Unitor™ Descalex™ should not be used on aluminium, zinc, tin or galvanised surfaces.

After use of Unitor™ Descalex™ a 0.5% solution of Nalfleet™ Alkalinity Control in fresh water should be used for neutralisation.

Unitor™Chemical Cleaning Unit:产品编号737189

有关除垢操作安全性的说明:

Unitor™Descalex™含有强酸。小心操作并特别注意材料安全数据表和/或产品卷标。使用推荐的个人防护设备。

来自除垢产品中的酸组分的反应产物可包括气体如二氧化碳和氢气。可以使用通风口上的气体检测设备监测氢气的形成。为避免窒息和潜在的爆炸性气体,在排出清洁溶液后,应通过用水清洗系统来安全地清除气体。出于同样的原因,必须提供除垢操作期间系统的排放。

必须持续使用气体检测设备

在进行除垢操作后进入密闭空间检查之前检查大气是否安全。循环除垢溶液时,始终在底部进口处循环,以避免气穴和气态反应产物的捕获。

使用说明

循环为最有效的去垢方法,如用于小型组件,也可使用浸泡方式。如欲清洗的设备含有油,油脂及污垢时必需先用TankleenSeaclean清洗

稀释DESCALEX的浓度到2.5 %-10%之间,取决于水垢范围的大小。此时其溶液的颜色是红色;当颜色变为橙色时,其酸性已被中和了85%;酸性已被全部消除,当酸已被完全中和后,其溶液应为无色。在清洗过程中,溶液应加热至60℃。

中和过后的残余溶液可重复使用,添加DESCALEX至颜色变为红色,但应不超过两次。

DESCALEX不可用于铝、锌、锡及镀锌表面。

酸洗锅炉、主机冷却水系统、冷凝器、淡水机、热交换器等,请参考WILHELMSEN实用手

册。

酸洗效果增强可藉添加一份的盐(普通的食盐)20份的DESCALEX,如没有盐,亦可将DESCALEX溶于海水中。使用DESCALEX酸洗后,可以0.5%Alkalinity Control的水溶液() 来中和余酸。
