Q: Will The Chlorine Use Be Reduced 70% Or More On A Spa The Same As UV Systems Installed On Pools?

A: Yes, the user should expect the UV system to do the total job of water bacteria elimination and thus, reduce the need for Chlorine (or similar oxidizer) to only oxidize the organic soils in the spa. This is how UV systems are able to achieve the dramatic Chlorine use reduction that occur after UV installation.

Q: Are There Any Special Requirements When Using A Delta UV System On A Spa Or Hot Tub?

A: All Delta UV Systems are equally at home whether installed in a spa, hot tub, swimming pool, water feature, or pond. Proper sizing of the UV unit to the pump output flow rate is the only consideration besides physical size limitations (portable spas)

Q: What UV System Series Is Best For Spas And Hot Tubs?

A: 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 AquamaticT) Series is perfect for placement under the skirt of the spa due to its compact physical size. However, it should be noted that the reduced physical size limits the spa water flow rate through the EA unit to 23 GPM (87 LPM) maximum flow rate. Thus, the most common use is to utilize the small continuous circulation pump of the spa system (if the spa is a continuous circulation type) or if not, then install the EA series system with its own small continuous circulation fractional HP pump. If the spa is an in-ground type with the circulation equipment located separately from the spa, then either the E or ES Series would be the perfect system for the spa. Remember that regardless of the Series selected, it is important to keep in mind the maximum flow rate for the UV system selected.

Q: What Chemicals Are Introduced Into The Spa By The UV System?

A: No chemicals of any nature whatsoever are introduced into any body of water by the UV system. All sanitation of the spa water takes place inside the UV system's wet chamber by the killing of the micro-organisms and bacteria that enter the UV unit.

Q: What If The Spa Has Only A 230V Power Source?

A: All Delta UV Systems are available in 230V (240 V 50/60 Hz) models. Consult the Data Sheet for the Series of interest, to obtain the 240V model number.
