The D series offers a safer pool experience for your family, friends and the environment. UV light helps to reduce algae, viruses and microorganisms without adding additional chemicals. Installing a UV system reduces chemical usage and breaks down chlorine by-products called chloramines. Chloramine exposure commonly leads to stinging (red) eyes, skin irritations, asthma and allergies. Sizing your UV system is important and based on the flowrate. Models in this series range from 46 - 110 gallons per minute. The D series is similar to the E series, however this series offers inline hardwired integration to perform automated treatment. The E series is a plug & play operation that runs independently from other treatment equipment.​
