LOW PRESSURE UV IS THE PROVEN GREEN SOLUTIONTwo UV technologies exist: Low-pressure (LP) and Medium-pressure (MP). Both UV technologies inactivate dangerous pathogens and irritating Chloramines but MP UV systems cost almost 3x more to operate than LP. In the past, Medium-pressure UV systems were believed to be more effective than Low-pressure due to MP’s high UV-C light output and compact package, but over the years LP UV lamp technology has improved to the point where LP lamps are now 5x more powerful than they were initially. Today, LP UV lamp technology continues to evolve and has significantly narrowed the gap of number of lamps required between MP and LP UV systems. The result is that LP UV systems now cost nearly 3x less to operate than MP UV systems.
LP and MP UV lamps operate very differently. MP UV lamps convert 11-15% of their input electricity into UV-C light. LP UV lamps convert 35-40%, making them much more effective and cost-efficient at germicidal disinfection and Chloramine control.
Spectra AbsorptionThe data displayed in the Spectral Absorbance chart below is universal according to the laws of science; it applies to all Low-pressure and Medium-pressure UV systems. The chart also identifies several materials associated with swimming pool water at the specific wavelengths that inactivate them.

MONEY-SAVING FACTSConserve Free-ChlorineMP UV lamps decay Free-Chlorine (see Spectral Absorbance Chart) which increases operational cost. LP UV lamps are proven to conserve Free-Chlorine, saving you money.
Low Heat OutputLP Amalgam lamps operate at 180°F, MP lamps at 1,600°F. The extreme heat generated by MP UV lamps intensifies the problem of quartz sleeve fouling and creates the need for expensive and problematic quartz sleeve wiping systems. This ultimately complicates equipment maintenance. BioShield Amalgam UV lamps operate at a fraction of that heat output and do not require the addition of a quartz sleeve wiping system.
Longest Lamp-LifeLP UV lamp life of 12,000 hours, outlast MP lamps by as much as 3 times. Even with the need for additional lamps compared to MP, the high cost and short life of MP make LP UV up to 3 times less costly to maintain.
For example: a 288,000 gallon pool using a MP UV system, operating at 800 GPM, and delivering a UV dose to 60 mJ/cm², replaces MP UV lamps annually at a cost of $1,120 each ($3,300). Compare that to a LP UV system which replaces 7 lamps annually at a cost of $160 each ($1,120).
Proof Is In The Science Regardless of UV system manufacturer claims, the Spectra Chart below clearly illustrates just how much more efficient LP UV technology is compared to MP at inactivating waterborne pathogens and Chloramines. The chart reveals the spectral output of both LP and MP UV lamps and the specific light-spectra that inactivates pathogen-DNA, Chloramines and Free-Chlorine.
SIZING YOUR BIOSHIELD® UV SYSTEM1. Establishing flow rate requirements in GPM is critical to selecting the correct UV system for your application.
2. Know Target Dose. Target Dose depends on the intended purpose of the UV reactor. While this can be complicated, the following rules-of-thumb are often used at minimum:
UV Dose Standard Commercial Application
40 mJ/cm² Inactivation of chlorine tolerant pathogens
60 mJ/cm² Additional breakdown of Chloramines for greatly improved air and water quality
3. Standard Commercial Application. Select desired UV dose column below. Identify maximum flow rate that meets system flow rate requirement. Complete this step for model CLP4 or CLP6 and with provided vessel and power enclosure dimensions, choose the best model suited for the mechanical space. *Note: Small port size may restrict actual maximum flow rate.

THE PROVEN SOLUTIONHealthy swimming is a matter of clean water and air conditions. Whether you swim in a residential or public pool, pool water and air quality can make you sick.
UV has proven to be a solution for dangerous RWI’s (Recreational Water Illnesses) and Chloramines (Chemical Irritants). UV Treatment is as natural as sunlight. More specifically, UV-C light is a natural component of the electromagnetic radiation that the Sun emits. Much of the Sun’s radiation is absorbed by ozone in the Earth’s upper atmosphere, but some UV-C light passes through and inactivates exposed microorganisms, including those found in surface waters.
UV systems operate the same way. Inside a UV system, UV lamps emit UV-C light (wavelength range 240-280 nm). Waterborne pathogens in the water circulating through the UV vessel are exposed to the UV-C light for a determined amount of time and become inactivated.
SOLUTION FOR GERMS THAT CAUSE RWI’SUV is instant germicidal disinfection, Free Chlorine is not. UV disinfection inactivates germs (Giardia and E. Coli.) most commonly associated with RWI’s. UV disinfection provides instant (single-pass) treatment unlike Free-Chlorine and ozone.
UV systems are a “Green” Technology and deliver multiple benefits contributing to healthy swim water.
REDUCED CHLORAMINESIf you have swimmers and pool staff suffering from eye and nasal irritation, it ’s most likely the result of high Chloramine levels (Dichloramine and Trichloramine). Chloramines, by-products of Free-Chlorine disinfection, form when the Free-Chlorine reacts with ammonia (sweat, urine and other waste from swimmers) in the pool water. As Chloramine levels build, they release into the atmosphere. Warm temperatures, unacceptable pH, high bather use and inadequate turn-over (filtering) are the most common causes of high Chloramine levels. The typical solution pool operators use to solve their out-of-control Chloramines problem is “Super-Chlorination”, which is to increase Free-Chlorine from 1.0/I to 5.0 mg/I, but UV systems are a gentler and more effective solution.
UV SYSTEMS ARE PROVEN TO BE VERY EFFECTIVE IN THE TREATMENT OF CHLORAMINESSpecific wavelengths of UV light will break down the bonds of chloramine molecules, effectively destroying them.
