The Natural Choice for Safe, Clear, Sparkling Pool Water Our salt chlorination systems are sourced to suit New Zealand conditions. Systems range from economical standard 20 AMP and 30 AMP units to the advanced 'ESCpH Self Cleaning Series' with automatic pH control.There is short but a nice article on this site http://www.enceechlor.com/technology.htm A salt water chlorinator starts with AC voltage whether it be 115 or 230v depending on where you live. then it is converted to 7v-12v dc either through electronic circuit boards or original methods, first through a dimmer (household dimmer works fine, provided it can handle an inductive load, not a resistive load) then through a step-down transformer and then through a rectifier which converts it from AC to DC and then through an Ammeter. this gives you full control over the power and shows an output of chlorine into the pool. The salt cell receives the DC power and is sent to an anode and a cathode or basically a positive and a negative plate or set of plates depending on what type of salt cell it is.
How does a Salt water chlorinator work
Salt water chlorination , is a process that uses dissolved salt (2,500–6,000 ppm ) as a store for the chlorination system. [ 1 ] In order to achieve this concentration, the chlorine generator (also known as salt cell, salt generator, salt chlorinator) uses electrolysis to break down approximately 200-500 pounds of salt ( NaCl ). The resulting chemical reaction eventually produces hypochlorous acid ( HCIO ), and sodium hypochlorite ( NaClO ), which are the sanitizing agents already commonly used in swimming pools. As such, a saltwater pool is not actually chlorine-free; it simply utilizes a chlorine generator instead of direct addition of chlorine.
Salt water chlorination
Electronic pest control is the name given to the use of any of the several types of electrically powered devices designed to repel or eliminate pests, usually rodents or insects Numerous electronic pest control devices are readily available throughout the world. Hardware stores and garden centers usually stock some sort of electronic device advertised to repel a variety of pests and one can also find them on the internet. Although these devices have been around for at least 20 years, they have only recently become popular and widely advertised, probably due to their environmental friendliness claims. There is a wide range of opinion about these devices. Some people claim that they work for them, while others claim they are not effective at all.

High-frequency mosquito repellents don't work, study finds
Insect repellent
An insect repellent is a substance applied to skin, clothing, or other surfaces which discourages insects (and arthropods in general) from landing or climbing on that surface. There are also insect repellent products available based on sound production, particularly ultrasound (inaudibly high frequency sounds). These electronic devices have been shown to have no effect as a mosquito repellent by studies done by the EPA and many universities. [ 1 ] Insect repellents help prevent and control the outbreak of insect-borne diseases such as malaria , Lyme disease , dengue fever , bubonic plague , and West Nile fever . Pest animals commonly serving as vectors for disease include the insects flea , fly , and mosquito ; and the arachnid tick .Ultrasound
Q. Should I be able to hear any sound from this unit? A. People with good high frequency hearing may hear some of the sounds. Q. Will the ultrasonic sound penetrate through walls or flooring?
