What is the simpliest unit for cleaning reactors?

• Compact barrel

• Mobile cleaning unit

• Narrow barrel

• Mobile cleaning unit

Choose the correct statement(narrow barrel)

• The cleaning system equipped with a narrow barrel is capable of performing targeted cleaning

• It allows slowly and smoothly clean the entire tank

• It allows intensively clean those areas where toxic liquids are particularly firmly deposited on the walls

• all of them

Choose the incorrect statement (mobile cleaning unit)

• The mobile cleaning unit can be moved to the manhole and fixed to the reactor

• The installation can be of an manual type, stay in place type, non-lifting mechanism and other types

• The installation depends on the size of the structure and the purpose of application

• It's widely used in polymerization tanks, reactors, fermentation tanks etc..
