We have adopted Hi-Rex, which is well-received by a wide range of users as a packing material for exhaust gas treatment, and it is a highly efficient unit-type scrubber unlike any before. By exchanging the packing material according to usage conditions and efficiency, it can respond to load fluctuations. The necessary equipment for gas treatment is delivered set on a common base, making installation on-site easy. Once the utilities are connected, it is ready for immediate use. 【Features】 - Adopts Hi-Rex, which is well-received by a wide range of users as a packing material for exhaust gas treatment, and it is a highly efficient unit-type scrubber unlike any before. - Can respond to load fluctuations by exchanging the packing material according to usage conditions and efficiency. - Delivered set on a common base with the necessary equipment for gas treatment, making on-site installation easy. - Ready for immediate use once the utilities are connected. - The scrubber body is made of FRP, making it lightweight, strong, and highly corrosion-resistant.
