HOW DOES THE JAC PAC SYSTEM WORK

When the JAC PAC is properly wired and plumbed into your system, the water circulates through

the PATENTED TRIPLE VENTURI FLOW CHAMBER, which houses a custom HIGH

INTENSITY GERMICIDAL ULTRA VIOLET LAMP. When water born bacteria or pathogens

pass through the JAC PAC CHAMBER, they are exposed to the high intensity germicidal ultra

violet rays, which in turn disrupts the D.N.A. BONDING. This then immediately stops the breeding

process and consequently the bacteria or pathogens die. As well, the JAC PAC is extremely

effective in killing other micro-organisms such as mould spores, viruses and even some pathogens

such as legion Ella and pseudomonas that recommended amounts of chlorine or bromine don't kill.

The unique design of the flow chamber assures the highest kill rate. You will also eliminate most of

your chemical maintenance program as the JAC PAC does not require perfectly balanced water

to function effectively.

The Electromagnetic Spectrum

The lethal range of UV radiation for bacteria occurs in the ultraviolet spectrum, which is between

X-rays and visible light. However, the whole U.V. range is NOT germicidal. Only the U.V.-C

(short wave U.V.) and some of the U.V.-B (middle wave U.V.) are germicidal.

The JAC PAC units we manufacture operate at the optimum effective wavelength of 253.7

nanometers. This frequency is used because this wavelength is the most effective in killing bacteria

and other micro-organisms which lie below 300 nanometers (sun tanning range). The wavelength

most effective in producing ozone, an undesireable by-product, lies below 200 nanometers (ozone

range). As we are only interested in killing microbes, we chose an optimum UV wavelength of 253.7

nanometers.

The Lamp

U.V. light emissions are created by a electrical current flowing through the mercury vapor between the

electrodes of the lamp. U.V. lamps (low pressure mercury vapor) produce the majority of their U.V.

output at 253.7 nanometers, which is the closest we can get to the optimum of 260-265 nanometers.

Because glass is opaque to ultraviolet radiation, U.V. germicidal lamps are built with U.V. transmitting

quartz and housed in a fused silica or quartz sleeve to allow 98% of the U.V. energy to be transmitted

to the water.
