The DEMA Blend Center with its modular design lets you easily couple together any number of stations (4 shown) to create a system that meets your specific needs, eliminating the need for excessive, costly inventory.
Now you can have a completely customized system that precisely blends liquid detergents or other chemicals with water at just the push of a button. These high quality molded plastic modules work in tandem with DEMA's new Action Gap backflow preventer. The Action Gap has met the American Society of Sanitary Engineering's (ASSE) 1055B standards for backflow prevention, and IAPMO Research and Testing, Inc.'s requirements for classification in the Uniform Plumbing Code (UPC). The Action Gap is virtually immune to hardwater conditions and successfully prevents mineral buildup. It also boasts design features that greatly reduce foaming generated while filling spray bottles.
Blend center proportioners dispense precise amounts of liquids into open containers or bottles from a decentralized work station. The push buttons can be locked in place to easily fill large containers.
Blend ratios and the proportion of chemical to water are set by interchangeable, color-coded, threaded metering tips. All valves and proportioners are easily accessible for servicing and blend adjustment.
