Directions for use

Recirculation method in-situ
For this cleaning procedure the engine needs to be stopped and secured. Permanently installed spray nozzles in combination with a cleaning solution tank and pump, such as the Unitor™ Chemical Cleaning Unit should be used. It is advised to blind off the cooler outlet. Properly mix water and 10-30% Unitor™ ACC Plus™, depending on the severity of the contamination, in the tank. Connect the pump's outlet to the nozzle assembly and the air cooler drain to the tank. Start the pump and spray the solution through the nozzles over the entire surface of the cooler and drain back to the tank. Circulate the solution for a period of 1 to 6 hours. After cleaning, rinse with fresh water. Remove the outlet blind and disconnect the pump and tank loop.

Soaking method in-situ
For this cleaning procedure the engine needs to be stopped and secured. Blind off the cooler outlet and flood the cooler with a solution of 10-30% Unitor™ ACC Plus™ in water depending on the severity of the contamination. Soak for a period of 1 to 6 hours and drain to slop tank. Agitation by means of steam or compressed air will improve the cleaning effect. After cleaning, rinse with fresh water. Remove outlet blind and close drain.

Out of Service Cleaning:

Soak bath method
Remove the cooler from the engine and place in a soak bath filled with a solution of 10-30% Unitor™ ACC Plus™ in water for a period of 1-6 hours. Agitation by means of steam or compressed air will improve the cleaning effect. After cleaning rinse with fresh water and reinstall the cooler. This method is also suitable for machine parts with stubborn carbon deposits.

Hand spray method
For this cleaning procedure the engine needs to be stopped and secured. Open the inspection cover on top of the cooler and the drain valve. Spray undiluted Unitor™ ACC Plus™ into the tube nest, with e.g. a Unitor Jet Spray Unit, and allow to penetrate into the deposits for a minimum of 1 hour. Rinse thoroughly with a high pressure jet such as a Unitor High Pressure Machine. Close inspection cover and drain.

In-service cleaning
The general principle is to inject a solution of ACC Plus™ into the air trunking upstream of the charge air cooler followed by a clean water rinse. For efficient cleaning of air coolers, it is necessary to use correctly installed dosing and injection equipment. To calculate the amount of solution required to clean an air cooler, calculate or find the cross-sectional area of the cooler and use 3 litres of cleaning solution per square metre or as table below:

For in-service cleaning of air coolers and the air-side of turbochargers, a solution of 25% Unitor™ ACC Plus™ in freshwater is recommended.
The appropriate dosage of cleaner is then placed in the dosing pot and injected up stream of the air cooler for a period of 10 minutes. After a further 10 minutes, a similar quantity of fresh water is injected to rinse off the emulsified deposits. Rate and frequency of application depends mainly on the condition of the air coolers. However when starting with the use of Unitor™ ACC Plus™, recommended injection is every 24 hours. After the initial cleaning period, the cleaning effect should last for 48 hours of operational time. Although frequency of cleaning may vary, the calculated cleaning dose should remain the same. This cleaning method is only recommended if approved by the engine manufacturer!

使用说明

原位再循环方法

对于此清洁程序，需要停止并固定发动机。永久安装的喷嘴与清洁溶液罐和泵组合，例如Unitor™化学清洗应该使用单位。建议关闭冷却器出口。根据污染严重程度，在水箱中适当混合水和10-30％Unitor™ACC Plus™
。将泵的出口连接到喷嘴组件，将空气冷却器排放到油箱。启动泵并将溶液通过喷嘴喷洒在冷却器的整个表面上并排回罐中。

将溶液循环1至6小时。清洁后
，用清水冲洗。拆下出口百叶窗并断开泵和水箱回路
。

原位浸泡法

对于此清洁程序，需要停止并固定发动机
。根据污染的严重程度
，将冷却器出口遮挡并用10-30％Unitor™ACC Plus™溶液浸泡冷却器。浸泡1至6小时，然后排入污水池。通过蒸汽或压缩空气搅拌将改善清洁效果。清洁后，用清水冲洗。取下出口盲板并关闭排水管
。

停机清洁
：浸泡浴法

从发动机上取下冷却器
，放入装有10-30％Unitor™ ACC Plus™水溶液的浸泡浴中
，保持1-6小时


。通过蒸汽或压缩空气搅拌将改善清洁效果
。清洁后用清水冲洗干净并重新安装冷却器。该方法也适用于具有顽固碳沉积物的机器部件。.

手喷法

对于此清洁程序
，需要停止并固定发动机。打开冷却器顶部和排水阀顶部的检查盖。将未稀释的Unitor™ACC Plus™喷入管巢中，例如Unitor喷射装置，允许浸入沉积物至少1小时。用高压喷射器彻底冲洗
，例如Unitor高压机
。关闭检查盖和排水管。

运转中清洁

一般原则是将ACC Plus™溶液注入增压空气冷却器上游的空气管道，然后进行清水冲洗。为了有效清洁空气冷却器，必须使用正确安装的计量和注射设备。

计算清洁空气冷却器所需的溶液量，计算或找到冷却器的横截面积，每平方米使用3升清洁液或如下表所示：

Engine HP                                         Solution mix. with 25% ACC Plus

6,000 to 12,000                                 3 litre mix

12,000 to 24,000                               4.5 litre mix

24,000 or more                                  6 litre mix

对于空气冷却器和涡轮增压器空气侧的在役清洁，建议使用25％Unitor™ACC Plus™淡水溶液。

然后将适当剂量的清洁剂放入计量罐中并注入空气冷却器的流中10分钟。再过10分钟后，注入类似量的淡水以冲洗掉乳化的沉积物
。施用率和施用频率主要取决于空气冷却器的状况
。

但是，当使用Unitor™ACC Plus™时
，建议每24小时注射一次。在初始清洁期后
，清洁效果应持续48小时的操作时间。虽然

清洁频率可能不同，计算的清洁剂量应保持不变。仅在发动机制造商批准的情况下才推荐使用此清洁方法！
