Specifications include, but are not limited to: a. This section covers equipment, accessories and supplier’s services required to provide a closed vessel, pressurized flow, medium-pressure ultraviolet (MPUV) lamp disinfection and chloramine control system with a UV intensity monitoring and control system. The MPUV system shall be complete and operational with all control equipment and accessories as shown and specified herein.; b. The MPUV system shall have been manufactured and/or assembled in a facility that is ISO9001 certified (shown upon request). Production in a non-certified facility shall not be acceptable.; c. Upon Owner’s request, the manufacturer shall provide documentation demonstrating that the UV product line has been verified to have proper chamber design characteristics via testing with the computational fluid dynamics (CFD) method by testing the chamber with the lowest power to flow rate ratio. Systems not assessed via CFD modeling shall not be acceptable.; d. The MPUV system shall have been certified according to NSF Standard 50 Annex H. Non-NSF certified systems shall not be acceptable.; e. The MPUV system shall meet the minimum requirements of any US local, state or national code covering the design, manufacture, installation or operation of ultraviolet systems in aquatics applications.; f. The MPUV system shall have been manufactured and assembled by a UL certified facility and certified to UL standards.; g. The MPUV system shall utilize electronic power supplies as the method for driving lamps in order to save money due to reduced power consumption. Systems using electro-magnetic ballasts and transformers as a method of driving lamps shall not be considered equal.; h. The MPUV system shall have continuous, step-less, real-time, self-adjustment of lamp output to optimize and tailor the dose to changing water conditions and to reduce energy consumption. Systems with timer based power stepping, stepping or systems with no automatic lamp adjustment shall not be considered equal.
