 PURIFY YOUR AIR




CI: Smoking is a big problem – can Ionair and this technology really help deal with it? SW: The problem is that people are always smoking, so if you are sitting next to a person that is smoking you won’t notice the benefits to the air because they are blowing smoke on to you, right next to you. We found that out in Hong Kong, where people sit five in a row on a table, and the cigarettes are always around, held down by someone’s leg, so it’s constantly coming up and you can’t do much about that. There are several ways of treating smoke in a casino. Engineering-


wise, you could take 100% outside air and exhaust all the air but that is very expensive not only from an electrical cost, it takes a lot of machinery to do that – so there are also maintenance costs. You can use an ionisation system, or you could use an activated carbon system. That is carbon cells that actually absorb the smoke molecules but it is expensive to replace.


Ionair – which is the Swiss company we represent – has been doing this for 25 years. I’ve been with them since the year 2000, and we have worked on many of the casinos in Macau. We have done several in Las Vegas too.


CI: Climate control, air con, purification – it’s all very expensive for a casino, is this just another cost on top? SW: One of the most appealing things about this system is that the process is almost no cost electrically. The whole system for a good-sized place might be 400 watts of energy consumed by the tubes; they are inserted in the air conditioning system, in the duct work going out and the intensity of the tubes is dictated by the IAQ sensor. That will cause the tubes to go off and on at a different rate. Some people will just put their tubes in the duct and turn them on and leave them, but that will cause another situation which is called ozone – that’s not good for your players, as it can make them drowsy. We have an ozone sensor in the system and it makes sure the ozone never gets above an accepted level which is programmed into the system. Ozone is always a by- product of ionisation and it needs to be handled correctly. With 100% outside air, well, in Europe that might not be so bad but


in Las Vegas that air can be 115 degrees in the desert… that won’t work. It’s still expensive to run, too, and the fans that run that are probably going to end up costing a lot more than the 400 watts we are talking about for our system. It’s a proven system, though you must understand that nothing will


ever completely get rid of smoke, it is a continual thing. But ionisation will also get into the carpeting and fixtures, the drapes, everywhere, so it takes smoke particles from everywhere, and the smell that comes with it. Smoke is one thing, smell is another.
