What UV System Series Is Best For Spas And Hot Tubs?
– The type of spa determines which Series should be used. If the spa is a portable spa, with equipment placed under the spa skirt, then the physical size of the UV system becomes an issue. The Delta UV (Elektra Aquamatic™) EA Series is perfect for placement under the skirt of the spa due to its compact physical size. However, it should be noted that while the reduced physical size limits the spa water flow rate through the EA unit, the High Output EA units allow a 69 GPM (216 LPM ) maximum flow rate. Thus, with the introduction of the High Output EA units, higher flow rates are now available then were possible when spa UV systems required a small continuous circulation pump in the spa plumbing system. If the spa is an in-ground type with the circulation equipment located separately from the spa, then either the E A-3H or EA-4H High Flow Series would likely be the perfect system for the spa. For larger in-ground spas, the E or ES Series should be considered. Remember that regardless of
