Page 2 of 3 <br /> <br /> Variable Frequency Drives (VFDs) <br />o Controls the pump output power and electrical draw based on filter and <br />circulation needs and demand <br />o Reduces pump electrical use by 20% to 25% <br />o NOTE: Some Utility companies are providing grants or incentive credits for <br />installing VFDs. <br /> State of the art chemical and pool controllers (linked via web access for off-site <br />monitoring and smart control) <br />o Provides more consistent and accurate control of pool systems, chemical levels, <br />water levels, and temperatures <br />o Provides direct alerts to pool operators and management of any problems in order <br />to identify and address problems in a more timely fashion <br />o The existing Lino Lakes Pool Facilities does have currently good Pool <br />Controllers, although the Pool Controller technology does improve each year <br /> High efficiency pool heaters <br /> HVAC Technology <br /> LED lighting <br />o Including zone and intensity controls to manage light levels based on time of day, <br />usage, and specific event needs <br />o NOTE: Grants sometimes are available for converting buildings to LED lights. <br /> <br />At this time in the ISG facility analysis, ISG is not recommending any changes to the Aquatic <br />Facility operating equipment since the existing equipment is in good shape and has been well <br />cared for. ISG is only recommending that the City understand the various options that would <br />exist for the Aquatic Facility in the future as the existing equipment grows older, out of date or <br />falters in any way. The cost savings for new upgraded modern technology is significant, <br />however, at this time in the process the pay back period would be too long to make it reasonable. <br />When the systems reach the end of their life cycle, then the pay back would make it reasonable <br />to consider the new technology options available. <br /> <br /> <br />Examples of State of the Art Pool Mechanical Systems <br /> Regenerative Media Filters UV Purification System <br /> (Neptune Benson Defenders) <br />
