Combustion research associates manufactures various types of customized equipments. Being a part of that scrubber is based on the compatibility with the working medium, toxicity, operating parameters, economy and long life of equipment. These scrubbers are used for chemical, petrochemical, food processing, pharmaceutical and related industries. The scrubbers offered are of regenerative or non-regenerative type
