MAP model wide range mixers are designed to provide correct mixture when the difference between minimum and maximum flow rate requirements (like closed head sprinkler systems) are wide. Thanks to their variable geometry, water and foam concentrate passage are continuously changed by using tandem working caplets. MAP models bladder tanks mixers are the perfect solution when a single system should feed various flow rate demands of the multiple scenarios. Each MAP mixer is calibrated one by one by our factory to guarantee correct functionality over the range.
