Ultraviolet Disinfection Equipment: Shall operate within the UVC electromagnetic spectrum emitting wavelengths in the range of 200nm to 400nm. This required wavelength will provide constant disinfectionlinactivation of bacteria, algae, molds,viruses and destruction of Monochloramines, Trichloramines,and Dichloramines. Ultraviolet Lamp/Chamber and Spectra Touch Control Panel by Engineered Treatment Systems (Telephone 920-885-4628, Fax 920-885-4386)or Architect/Engineer approved equal.Any deviation/exception must be provided in writing to and approved by the designer no less than ten days prior to the bid date. B. The UV System shall have an MET or equivalent(ETL, GSA, or UL)listing, be NSF-50 2010 certified including Section 13 and 3rd party validated to the USEPA UVDGM 2006 Guidelines. 1. Equipment General Description a. The Ultraviolet System shall be provided in a complete package to include: 316L Stainless Steel Chamber,Spectra Touch Control System located in a NEMA 12 rated panel, Medium Pressure Bulb(s)designed to emit wavelengths within the UVC electromagnetic spectrum,strainer basket automatic wiper system,and Project Commissioning by a Certified ETS Ultraviolet Technician. 2.02 UNIT TYPES— ECP Units: Ultraviolet manufacturer tD offer unit capability of a horizontal OR vertical installation application using state of art design and direct flow through characteristics. Direct flow will be required in order to reduce total head loss through the system. Unit shall be a Single Lamp medium pressure system with a bulb of 1.3 kW power range. ANSI flange of 3"and flow pattern of up to 260 GPM @ 95% UVT,Any systems validated or designed for flows based on 98% UVT are not acceptable- Chamber and Control Cabinet shall be as indicated on the drawings. The electrical requirements include either 208 or 220 volt single-phase power with a 20 amp external breaker. All required electrical work to be performed by licensed electrician. ETS Model ECP-113-5 single phase 22D volt validated flow rate of 260 GPM or equal unit ECF Units: Ultraviolet manufacturer to offer unit capability of a horizontal OR vertical installation application using state of art design and direct flow through characteristics. Direct flow will be required in order to reduce total head loss through the system, Unit shall be a Multiple Lamp medium pressure system with a bulb range of(2) 1.0 kW—(4)3.0 kW power range. Multiple lamp system is required in order to maintain quality disinfection in the event of a single bulb failure. ANSI flange range of 4"—12"and flow pattern of 360 to 37DO GPM. @ 95% UVT.Any systems validated or designed for flows based on 98% UVT are not acceptable. Chamber and Control Cabinet shall be as indicated on the drawings. Electrical requirements to include either of the following 208,240,480 or 575 volt 3-phase with a (XX)amp external breaker recommended by ETS based on the appropriate supply voltage.The electrical contractor is to take into account plus/minus 3%for external breaker. All required electrical work to be performed by licensed electrician. ETS Model ECF 220-8 3 phase 480 volt validated flow rate of 1100 gpm or equal unit ETS Model ECF 215-6 3 phase 480 volt validated flow rate of 665 gpm or equal unit 2.03 ULTRAVIOLET CHAMBER A. Pressure rated for 100 psi(tested to 150 psi), and pressure drop across the unit will be minimal. The unit shall be constructed of 316L stainless steel passivated to prevent corrosion within the harsh pool Environment. The Ultraviolet chamber shall come complete with the following equipment: B. Ultraviolet intensity monitor factory calibrated to provide intensity in mw1cm2 , monitors providing percentage of lamp output not acceptable. It must include a built-in alarm system to notify operator when output level drops below required level of 60 mj/cm2 for indoor pools or 40mj/cm2 for outdoor pools(or operator set dosing levels).
