Aqua Logics ALSV series of UV Sterilizers offer a unique compact design delivering a high UV dosage in a small footprint. Often space is limited in facilities and traditional horizontal UV sterilizers require not only space for the UV but also sufficient space to remove and replace the UV Bulbs.The ALSV UV's come standard with ballasts and can be ordered with control packages featuring lamp operation indicators, lamp hour meters, and high temperature air and water cut out switches.
