The Emperor Aquatics SMART Aquarium & Pond UV Sterilizers are designed for superior performance. Each model is properly designed around its UV lamp's length and UV output. They are physically larger because they offer a greater UV exposure area. Water inlets and outlets are tangential, creating a spiral flow around the unit's protective quartz sleeve, which holds the UV lamp. This increases the contact time between the target microorganism and the UV lamp. The UV lamps are always positioned between the water inlet and outlet ports, using all of the UV lamp's length and available UV energy to sterilize the water.

These units feature exclusive easy-service quartz sleeve module and large internal view ports for monitoring the condition of the UV lamp. All feature long life (9000 hour) T5 hard quartz glass UV lamps for maximum performance and longevity. The 25 Watt models have 26 foot cords with in-line water-tight ballasts and larger models feature a watertight power supply with a 16 foot power cord. All housings are molded in a black UV-resistant high-density plastic with a lifetime warranty against failure of the plastic due to UV light exposure.

Each model is available with 1-1/2" Slip Union fittings for ease of maintenance. This model includes PVC adaptors and 3/4" barbs for use with vinyl hose. Replacement Lamps and Quartz Sleeves for this unit are readily available.
