FREQUENTLY ASKED QUESTIONS ABOUT THE JAC PAC! Is the JAC PAC an Ozonator? Ans. NO. Although the JAC PAC shares some common technology ( U.V. Lamp), with an ozonator, there is only a very slight amount of ozone (2 to4 ppm. ) created by the JAC PAC. This slight amount of ozone never gets a chance to leave the chamber because as it is being created, it is just as quickly being destroyed by the germicidal U.V. rays emitted by the high Intensity lamp used in the JAC PAC. ( B.C. Research test data supplied upon request). What is an Ozonator ? An ozonator creates a toxic gas called ozone by combining oxygen with U.V. rays in the 180 Nanometer range. The ozone is then injected into the seafood tank in a gaseous form and as the water born pathenogens come into contact with the ozone, they are rendered harmless by being Oxidized. One of the problems with ozonation is the air born off gas. It is very harmful to humans as it can damage mucous membranes, eyes, inner ears, lungs etc. It can also be very damaging to the equipment, ie. tank covers, pumps, filters and what ever else it comes in contact with. Because ozone is such a strong oxidizer, it is not a good or safe choice of sanitizer for live sea food tanks as it has been found to remain in the water for up to 20 minutes before gassing off. The problem is it can cause bums resulting in tissue distinction to the sensitive areas offish ie. the gills and eyes and can destroy the stomach or digestive tracts of shrimp, crab, bivalves etc. thereby causing premature death and or deterioration to the subjects in the water it is treating. How is the JAC PAC different than an ozonator? Ans. The JAC PAC employs GERMICIDAL ULTRA VIOLET TECHNOLOGY which is known to be one of the safest and most effective forms of sterilization in the world. It operates in the U.V. wave length of 253.7 nanometers which is known to be the most lethal wave length for bacteria and carcinogens there is. It kills them by disrupting their DNA nucleus and renders them harmless. They cannot regenerate or colonize and thus die. Is the JAC-PAC safe? Ans. YES .The JAC PAC CHAMBER is made out of special high density food grade plastic which does not allow the transmission of U.V. rays outside of its walls thereby making it completely safe, not only to humans, but to the live seafood that is in the water it is sanitizing. Is the JAC PAC accepted for use in the live seafood industry? Ans. YES. The JAC PAC uses the latest ultra violet technology which now receives world wide acceptance by health authorities that are in the know. The wide range of bacteria and carcinogens that are destroyed by exposure to germicidal ultra violet is causing authorities to look at systems for use in all types of areas including drinking water, waste water, pool and spa water,ponds, aquariums etc. Is the JAC PAC easy to install? Ans. YES. The JAC PAC must be installed in the circulation or filtration system of the live sea food holding tank. Please contact the JAC PAC representative in your area. Is the JAC PAC C.S.A. approved? Ans. YES. The JAC PAC was CSA approved in 1993, and when installed in accordance with local electrical codes, it will conform to the highest standards any where in the world Is the JAC PAC safe to look at? Ans. YES. Ultra Violet light is only harmful when the lamp is looked at directly by the naked eye. A simple precaution is to wear glasses or safety goggles as Ultra Violet can not pass through glass or plastic. This is one of the reasons the JAC PAC works as well as it does. Inside the chamber we use what is called hard glass quartz to house the lamp and keep the water off it. This type of glass allows up to 98 % of U.V. transmission where as normal or soft glass allows very little to none. Hard glass will not solarize or deteriorate as will soft glass. Are there any harmful rays given off by the JAC PAC? Ans. NO. There are no harmful rays given off by the JAC PAC. The chamber is made from a special type of plastic which does not allow any U.V. transmission to occur outside of the chamber itself. This has been tested over a lengthy period of time with a U.V. Meter and has not shown even a trace amount of emission or radiation. How often should the JAC PAC LAMP BE REPLACED?
There are two reasons for this. The first one is to make sure the lamp is producing in the proper wave length (they are manufactured to perform at peak efficiency for 8,000 hours ). The second reason is that the quartz sleeve can become coated with mineral deposits there by reducing transmission of U.V. in the chamber and consequently resulting in poor water quality. The quartz sleeve should then be cleaned and replaced. This should only be done by a qualified JAC PAC Technician.
