The American Ultraviolet tank-mounted LTC (Liquid Tank Conditioner) Series, formerly the SC (Sterile Conditioner) Series, has become an industry standard for controlling microbial growth in Liquid Sugar and High Fructose Corn Syrup (HFCS) storage tanks. By using a combination of particle filtration (via a series of media filters), and microbial filtration (via UVC lamps like those used in medical applications), these units provide clean, disinfected air to the headspace, and have been doing so for decades. Of course we're always working on making our products more and more effective, and, over the years, we've improved the LTC Series with the addition of lamp monitoring, airflow monitoring, shatterproof-sleeved UVC lamps, and upgraded, standard components that enable the equipment to successfully operate outdoors. Thousands of custom units have also been made for various applications that require features not typically available on this type of equipment. Through the combination of satisfying the most common custom requests, incorporating innovations in materials, improved fabrication techniques, embracing industry trends, and, because of decades of our in-house design and manufacturing experience, we're very pleased to report that the facelift we've applied to our new LTC series has proven to be very well received by our customers.
American Ultraviolet always wants to ensure we are providing the best "UV filter" possible, so we turned to an independent testing lab to obtain HEPA Filter Penetration test verification for our new design. With a target of ≤0.03% penetration to pass HEPA Filter Penetration standards, we achieved an actual penetration of 0.0031% - 10 times better than the requirement to pass. This was achieved with the following changes to the LTC design:
Heavy gauge stainless steel construction that is continuously welded, which means every seam on the stainless steel UVC chamber and blower/filter enclosure of the new LTC is welded and ground smooth. This makes for an airtight enclosure, and eliminates 99.9969% of particulate matter before the UVC lamps are even factored in
Because there have also been advances in UV lamp, and electronic ballast, technologies over the last decade or two that specifically benefit this application, they were also included in the LTC facelift.
Finally, because we also felt it was important to simplify the offerings and options of our LTC Series, as part of our facelift we decided to offer an appropriate spectrum of available configurations, without creating unnecessary complexity. To this end, the LTC Series now offers, as standard options available at no additional cost, tri-clamp, flange and female-threaded pipe coupling connections to the tank in sizes of 2", 2.5", 3" and 4". Couplings are provided mounted to a stainless steel plate that in-turn mounts to the UV chamber, and are no longer welded directly to the chamber housing. This allows change-out of the tank connection without having to replace the entire fixture. All couplings are now stainless steel, as the traditional PVC 3" FPT connection has been replaced with a stainless steel version.
The standard LTC Series continues to be made from 304 stainless steel, but offers the option to upgrade to 316L stainless steel construction for applications and facilities requiring this grade of material.
Custom LTC Installation with additional heater element
Prolonged, direct exposure to UVC light can cause temporary skin redness and eye irritation, but does not cause skin cancer or cataracts. American Ultraviolet systems are designed with safety in mind and, when properly installed by a professional contractor, do not allow exposure to UV irradiation and allow for safe operation and maintenance.
Despite all the upgrades and additions to the LTC Series, there are still some add-ons, and features, that remain optional, including:
