TVT America LLC has the complete solution for your ATEX 94/9/CE Ex Explosion proof drive needs to go Global with your machines standards, enter new markets, and meet specification requirements in some of the most demanding applications and environments.
For machine builders seeking to export their machines into new markets, electrical standards, certifications, and voltages can be very challenging. From our production in Italy, and our assembly centers in North America, we are able to solve your motor and drive problems with the right solution, the solution that meets and exceeds standards, and the one with a global service & support network.
TVT products are known in applications like the milling of grains, dewatering of waste, compression of explosive gases, and pumping of toxic liquids. For Grain Milling, a ATEX Ex 1/21 2G/2D rated motor coupled to a ATEX 1/21 2G/2D is used to mill grains into flour. This flour is then filtered through a TVT Gauss Magneti filter to remove any ferrous particals.
In the filter pressing of solids in a waste-water processing facility, TVT's ATEX motors, variators, and gear reducers are first used in centrifuges to remove liquid from solids, then later in the process other TVT ATEX motors, variators, and gear drives, and high performance couplings are used to further press any remaining liquids from these solids in a filter-press machine.
TVT America offers one of the widest ranges of power transmission solutions in North America in metric drivelines. Beyond the motor, variator, and gearbox, we complete your solution with shaft couplings, belt and chain drive and conveyor systems, torque limiters, brakes, pneumatic clutches, shaft collars, locking elements, vibrating motors & sieves, as well as drum motors, magnetic lifting and separating elements, and linear motion.
Such a little company, with so many friends, giving its customers a complete solution... yet personal attention, and a global foot print.
The ATEX Ex, UL, CSA, CE, ISO, many certifications, specifications, and compliances allow TVT to meet your specific needs globably. Very large multinational corporations and small machine builders seeking to reach their market with the right solution look to TVT.
Let us show you what Made in Italy...Loved in America (and the world) means when it comes to you and your goals.
