Turboexpansion

<p class="t-p">For more than a decade, Calnetix Technologies has been at the forefront of turboexpander technology, designing, implementing and manufacturing some of the most innovative solutions for expanders across many industries. Calnetix was the first to bring a self-contained, fully integrated expander solution for industrial waste heat recovery to market and subsequently licensed the technology to GE and other OEMs. Since then, Calnetix has developed other <a href="/line-turboexpanders">turboexpander solutions</a> for the industrial and oil and gas industries to broaden the market impact of its technology. The Calnetix turboexpander is hermetically sealed and utilizes non-contact magnetic bearings to eliminate the need for lubrication. In addition, special encapsulation and canning technologies enable our products to be cooled by corrosive process fluids.</p>

Overview

<p class="t-p">Calnetix's <a href="/line-turboexpanders">FreeSpin™ In-line Turboexpanders</a> are a key technology element for achieving necessary pressure reductions while extracting usable clean energy. This technology has a beneficial impact on various industrial applications, such as air separation, gas liquification, steam pressure letdown and geothermal power recovery.</p>
<p class="t-p">Calnetix is working with major OEM producers of air and gas products on both compressor loaded and electric generator loaded turboexpanders utilizing our&nbsp;<a href="/high-speed-electric-motor-generators">Magnaforce™ motor generator</a>&nbsp;and&nbsp;<a href="/active-magnetic-bearings">Powerflux™ magnetic bearing</a>&nbsp;technologies. Calnetix’s Powerflux™ magnetic bearing technology requires no lubrication and provides non-contact operation without any wearable parts, therefore allowing for enhanced efficiency and reliability, while reducing lifecycle cost and eliminating the risk of oil contamination in the process.</p>


Industrial

<p class="t-p">Turboexpanders are used in many production and processing activities in the oil and gas industry from the extraction of hydrocarbon liquids from natural gas to energy recovery in petrochemical and gas pipeline pressure letdown.</p>
<p class="t-p">Calnetix <a href="/line-turboexpanders">FreeSpin™ In-line Turboexpander</a> systems run on magnetic bearings and are hermetically sealed in a single housing, eliminating the need for a gearbox, lubrication system or any auxiliaries. The in-line connection into existing piping systems provides little to no impact on footprint.</p>
<p class="t-p">Turboexpander systems with Calnetix’s <a href="/high-speed-electric-motor-generators">Magnaforce™ motor generators</a> are enabling newer applications in oil and gas, such as the energy recovery from natural gas pressure letdown. These natural gas turboexpanders extract energy from the pressure reduction required at various stages of gas distribution. This allows for the generation of additional electricity with no added pollution or energy input.</p>
