  • the seal 124 extends at least partway around the periphery of the cold plate 123.

  • the drying agent 200 in this embodiment is in the form of a molecular sieve and, in particular, a 4A molecular sieve.
  • the molecular sieve is located downstream of the device 100.
  • the filter 300 is located downstream of the drying agent 200.
  • the filter 300 assists in filtering particles from the air before the ozone generator 600. In this
  • the filter 300 is in the form of an inline air filter, comprising polyethylene, for air systems, compressors and vacuum applications. This allows particles in the air, measuring at least 5pm, to be removed and prevent contamination through particle build up in the ozone generator 600. This improves the longevity of the ozone generator 600. Indeed, it has been found that avoiding the build-up of particles in ozone generators is critical to prevent arcing and electrical shorts, particularly where the space between electrodes is relatively small.
  • air is drawn through the air filter 300, along with the device 100 and drying agent 200, via the pump 500.
  • the pump 500 is a vacuum / pressure diaphragm pump.
  • the pump 500 is configured to pump filtered dry air towards the ozone generator 600 from the outlet 14.
  • the pump 500 may be located downstream of the ozone generator 600 if it is an ozone compatible pump.
  • the fluid moving device may be in the form of a venturi injector.
  • the venturi injector may be located downstream of the ozone generator 600.
  • the venturi injector would normally be configured to create suction based on a water flow and, as such, ozone would be drawn directly into the water flow.
  • the controller 400 assists in controlling the fluid preparation system 10. Based on information from the temperature system 150 and humidity sensor 350, the controller 400 is configured to operate the device 100 and the pump 500. That is, untreated air is configured to pass through the casing 128. As it passes through the casing 128, the air is cooled substantially via the cold sink 125. The cold sink 125 is configured to transfer heat towards the hot sink 1 12 via the element 140. Accordingly, temperature sensor 150 provides temperature information of the cold sink 125 and air passing thereby.
  • the controller 400 regulates power to the element 140 in order to ensure that the air is reaching a predetermined temperature (and not overcooling the system).
  • the controller 400 powers on / off the device 100 to achieve a predetermined temperature.
  • the device 100 works based on a duty cycle to achieve a predetermined temperature for the air.
  • the controller 400 may activate the fan 130 to increase convection from the hot sink 1 12.
  • the predetermined temperature is associated with condensing of the air. That is, the air temperature is changed, towards its dew point, so that condensation is drawn from the air. This condensation may then form drops of water that fall from the device 100 under gravity via the inlet of the casing 128.
  • the device 100 is typically mounted in a manner that allows the inlet / outlet of the casing 128 to be facing in a vertical direction. Furthermore, this arrangement has typically resulted in approximately a dew point of 0°C to -10°C). Following this, the air is drawn through the drying agent 200. This typically results in most of the remaining water vapour being removed from the air dew point of -40°C to -80°C.
  • the air is drawn through the filter 300 to substantially remove particles that may contaminate the ozone generator 600.
  • the humidity of the air is measured by the humidity sensor 350.
  • the controller 400 is configured to provide an alarm that the relative humidity is high.
  • the alarm/alert in this embodiment is a visual indication in the form of an LED light.
  • the controller 400 may, based on detecting a relative high humidity, stop the pump 500. This in turn would prevent the fluid preparation system 10 from providing non-ideal air to the ozone generator 600.
  • the ozone generator 600 is configured to receive the dry filtered air from the fluid preparation system 10 and suitably produce ozone.
  • the ozone generator 600 may take the form of the ozone generator outlined International Application No.
  • fluid preparation system 10 may form a plug and play system for other ozone generators.
  • the fluid preparation system 10 normally operates under a simple vacuum air pump 500 as opposed to other systems using high pressure pumps. Furthermore, as the fluid preparation system 10 is relatively simple, and a heavy load is not placed on the drying agent 200, the fluid preparation system 10 is highly reliable and can typically work for a number of years without maintenance. The simplicity of the system 10 also results in a low cost and compact unit that quietly operates. The plug and play feature of the fluid preparation system 10 also allows for easy installation. The fluid preparation system 10 also avoids wasting of 'purge air' and has a low power consumption, minimising running costs.
  • the fluid preparation system 1 0 also provides a very dry and stable output of output of air to the ozone generator, particularly in view of the functionality of the controller 400.
  • the fluid preparation system 10 cools the air entering the ozone generator 600 and improves ozone output by cooling the electrodes of the ozone generator 600.
  • adjectives such as left and right, top and bottom, hot and cold, first and second, and the like may be used to distinguish one element or action from another element or action without necessarily requiring or implying any actual such relationship or order.
  • reference to a component, an integer or step (or the alike) is not to be construed as being limited to only one of that component, integer, or step, but rather could be one or more of that component, integer or step.
  • the terms‘comprises’,‘comprising’,‘includes’,‘including’, or similar terms are intended to mean a non-exclusive inclusion, such that a method, system or apparatus that comprises a list of elements does not include those elements solely, but may well include other elements not listed.
