The Colasit CANW ammonia emergency scrubber is installed for the removal of ammonia that has escaped from refrigeration systems. The emergency scrubber dimensions are tailored to the NH3 content of the refrigeration system and the volume of the central cooling system.

The emergency scrubber starts automatically in the event of an NH3 incident. The released ammonia is neutralized by the addition of sulfuric acid.
