FOAM DOSAGE SYSTEM WITH AUXILIARY CONTROLLER AND METHOD OF OPERATION OF A FOAM DOSAGE SYSTEM

摘要

Foam dosage system with auxiliary controller to achieve the invention refers to a foam dosage system.The foam -dispensing system may include a foam pump, at least one foam line, a Deviator and at least one controller. The skimmer can direct a portion of a liquid foam concentrate stream downstream of the foam pump back through the foam pump. The controller, which may be in communication with the foam pump and the skimmer, can be configured to automatically maintain a minimum flow of the liquid foam concentrate through the foam pump.
