Falling Film Evaporators
Goodway Benelux supplies equipment to clean the tubes of falling film evaporators. In time (or due to a production error), these will become fouled, leading to a reduced efficiency of the installation.

The AWT-100X is Goodway's most powerful device developed to clean heat exchanger tubes and pipes. The system is air-powered and therefore a favorite in the industrial cleaning sector. The device can be used with or without water.
The RAM-4X is a powerful device developed to clean heat exchanger tubes and piping. The system is equipped with a powerful motor for heavy-duty tube cleaning. The device can be used with or without water.
Goodway Flexible Shafts are widely used for various cleanings within Tube Cleaning. Think of cleaning heat exchangers, Chillers, Condensers and other cooling/heating systems. The blue colour stands for water rinsing.
Black, flexible shafts are used for dry cleaning activities on various installations. Such as; boiler fire tubes, heat exchangers and production- / transport lines. Equipped with a high temperature resistant outer layer (up to 149°C).
Flex hub centrifugal scrapers are used to remove hard deposits from tubes. With 4 different scrapers you can clean tubes from 13-102 millimeters (internal diameter). Also applicable for blocked tubes.
Nylon abrasive brushes are designed to clean internal tubes starting from 25 millimeters. The brushes are versatile and work best with a Goodway mechanical tube cleaning system.
Buffing Tools are self-adjustable cleaning tools. These can be used to drill open blocked tubes and/or remove heavy deposits from the tubes. The tools are self-adjusting and can be used for diameters from 7.9 to 76.2 millimetres.
Cleaning of falling film evaporators
Falling film evaporators are used in the food industry and in particular at factories active in the dairy industry. These installations have a relatively large number of tubes that will become fouled over time with the product that flows through them. Over time, especially with dairy products, this deposit can form into a very hard substance, sometimes resulting in blocked tubes.
In addition to the regular (CIP) cleaning procedure, it may be wise to periodically apply a mechanical cleaning with brushes and, if necessary, heavy-duty scrapers. The friction that is created will ensure that deposits on the tube walls are quickly released and flushed out of the tubes. It is also possible to open completely blocked tubes with specialist tools in the event of an emergency.
Applications and usage
The cleaning equipment for falling film evaporators can be used for almost any installation. Depending on the tube diameter, length and quantity of tubes, a set-up can be customized. In principle, a cleaning package always consists of:
- Tube cleaning system, such as the AWT-100X
- Flexible shaft
- Nylon abrasive brushes for regular cleaning and maintenance
- Scrapers for hard deposits and blocked tubes

Despite regular cleaning and good planning, problems can still arise that cause the tubes of evaporators to become fouled or clogged. In that case, equipment from Goodway Benelux offers a good solution. Many large factories already use this equipment for their preventive and/or reactive cleaning activities. Some examples are:
- Nestlé, Friesland Campina, Bel Group, Beneo, and more.
- The above companies use the Goodway AWT-100X system, read about their experiences here.
