Dinnissen offers the Hygienic Compact Containment system. The system is designed to seal off production processes to prevent the entry of fine particles or microorganisms that may be dangerous in the production of feeds and chemicals, according to Dinnissen. HCC system’s underpressure exerts pressure from outside the system to prevent hazardous substances from escaping from connections, seams or joints, through the use of inflatable and air seals.
