Manufacture of high power ultrasound equipment using Rubiitpower Technology has been focussed on the design of large flow - continuous treatment chambers (flow cells) causing the cost per volume material treated to be reduced Improved energy efficiency of the equipment. The efficiency of Rubiitpower ultrasonic generators and Processor transducers has been improved over the years, thereby reducing internal heating and provision of specially designed in-expensive cooling systems), Easy to install and/or retrofit systems with improved efficiencies, the size of generator, cooling system and other parts are easily installed into an existing facility at Competitive energy costs. Depending on the application, the amount of energy required per liter material treated (often defined as kWh/L) is comparable to any other type technology unit operation in the industry (for example homogenization, milling, heat shock, etc.) Low maintenance cost is One of the main benefits of Rubiit technology in the absence of moving parts,the lack of rotors, seals, grease, etc. makes these systems particularly robust.
Rubiit Technology is Strong potential for intellectual property. While high power ultrasonic Processor systems become more and more standardized, the way the energy is applied to the medium (for example, flow cell design, number of transducers, piping arrangement, etc.) is unique for every application. Therefore, the potential to obtain patent protection is relatively large.

Wax depositions in drilled oil wells are complex mixture of heavy solid alkenes, asphateues, sand grain, precipitated salts, rust and entrapped water and depend on wax content viscosity and flow rate loss of gas and temperature lowering below cloud point temperature (CPT) results in precipitation of wax and asphalteues increasing oil viscocity forming organic depositions choking off flow lines. Wax deposition and gelation renders pipe lines and pumping equipment unusable, reducing oil production rate and closure of wells. Ultrasonic processor transducers of 1000 – 5000 Watts are used
