The series comprises four types. The systems consist of a cylindrical reactor of acidproof steel with Spektrotherm® UV lamp in a quartz pipe. Equipped with UV sensor. Also available in PE. Selected systems are certified in accordance with the Austrian ÖNORM and the German DVGW standards. Biodosimetrically tested.
Ideal for filtration jobs with heavy demands on flow rates and space. Used for filtration of boiler water and cooling water, circulation water in district heating plants, rinse water in the surface treatment industry and in the electronics industry, as well as for process baths, etc.
The Grundfos digital dosing control is used for very precise dosing. The DME-type stepper pump motor rotates continuously, so that the material flows parallel to the suction. The engine automatically sets the dosage speed, while guaranteeing the required flow rate. The DMS motor rotates at a constant speed, stopping only between cycles. By automatically increasing or decreasing the speed, the DMS metering pump can adjust the flow rate to suit your requirements. For two types of metering pumps, dosing can be controlled remotely, analogously or manually.
The DDA, DDC and DDE models set new standards at dosing rates of up to 30 l/h and 16 bar. The DDA model is the pump for complex and demanding applications where the focus is on maximum process reliability. The DDC impresses with features such as simple, intuitive click-wheel operation and a graphic LC display. The DDE is the cost-effective entry-level model with all the benefits of Digital Dosing.
