This is simply a piece of stainless steel that blocks splattering of contaminated water from getitng directly into the distillation coil, which leads to a higher quality of distilled water. Although its nothing super sophisticated, it does dramatically increase the quality of the distilled water produced. You can slide it in and out of place, to test just how much fo a difference it makes during distillation! While covered up, as in the right hand side, this protects splattering of the bad stuff up into the distillation coil, and only allows pure distilled steam to force its way up into the distillation coil! Keeping the yucky stuff in the boiling chamber from splattering up into the coil gose a long ways to producing the best distilled water. Stainless steel in the interior where your water touches, composite material on the outside to prevent rust! The fan housing exterior is made of a composite material (non metal) like most distillers. The exterior is made of a composite material. Others are made of tin that rsut and dent easily. One less rubber gasket to wear out! You can see the old style (b) with the rubber around the coil tube coming into. Also the new styel (a) is less likely to get knocked out. Like to sell you a product with less aprts to break down. A few customers said they had problems with the old jug handle that it was hard to hold. Love our customers and have given you an easier to handle container on our love model 3 and above. We even added ‘friction’ bumps to the jug, so you can grip it better. 90% of the small counter top distillers that quit working, do so because of this blown fuse that is hard ot change. These are not normal fuses, they are thermal fuses designed to blow at a certain temperature. NI our goal of eternal perfection, we have replaced the fuse, with a heat sensitive circuit breaker! I recall just a few months aog about some johnny come lately claiming to be a service center in canada for brand x distillers, and he stated his distiller does not have a fuse in it. (even if they claim to be a service center). I ran one bathc of water through the distiller, and threw that batch away. After that, i cleaned the new container out with dishwashing soap, and then rinsed that out to make sure i got all the soap out! After that i made a new batch of water, and the water tasted fine! The reason i mention the above is. Its upgradeable to a glass container in the future. 1 gallon in 3 to 3 1/2 hours! Width of jug combined with distiller. Of quick distillation power than our other models! All in a brand new fresh unopened package! Our advertising is designed for the experienced distiller user.
