The primary product lines include fluid rotary unions and electrical slip rings. Fluid rotary unions reliably seal and transfer various fluids such as water, air, hydraulic oil, coolant, and steam from stationary inlets to rotating parts.Theprimaryproductlinesincludefluidrotaryunionsandelectricalsliprings.Fluidrotaryunionsreliablysealandtransfervariousfluidssuchaswater,air,hydraulicoil,coolant,andsteamfromstationaryinletstorotatingparts.
High-pressure rotary union product lines include GP Series, GPS Series, SE Series, and HPS Series, capable of handling pressures up to 20,000 PSI (1,375 BAR). The SE Series offers 2 to 24 flow passages with specifications up to 7,500 PSI and 300 RPM. The HPS Series features 1 to 16 flow passages and corrosion-resistant stainless steel construction suitable for marine and offshore environments, handling pressures up to 20,000 PSI (1,375 BAR). The GP Series provides 2 to 12 flow passages with specifications up to 7,500 PSI and 500 RPM.High-pressurerotaryunionproductlinesincludeGPSeries,GPSSeries,SESeries,andHPSSeries,capableofhandlingpressuresupto20,000PSI(1,375BAR).TheSESeriesoffers2to24flowpassageswithspecificationsupto7,500PSIand300RPM.TheHPSSeriesfeatures1to16flowpassagesandcorrosion-resistantstainlesssteelconstructionsuitableformarineandoffshoreenvironments,handlingpressuresupto20,000PSI(1,375BAR).TheGPSeriesprovides2to12flowpassageswithspecificationsupto7,500PSIand500RPM.
Electrical slip rings feature high-performance brush technology, transferring power, signals, and data (analog/digital) across rotating interfaces. The ES Series offers a low torque design, gold-on-gold contacts, and low electrical noise, with standard models from 6 to 56 circuits. An optional IP65 Rated Protective Enclosure is available for enhanced waterproof and dustproof capabilities.Electricalslipringsfeaturehigh-performancebrushtechnology,transferringpower,signals,anddata(analog/digital)acrossrotatinginterfaces.TheESSeriesoffersalowtorquedesign,gold-on-goldcontacts,andlowelectricalnoise,withstandardmodelsfrom6to56circuits.AnoptionalIP65RatedProtectiveEnclosureisavailableforenhancedwaterproofanddustproofcapabilities.
DSTI integrates fluid rotary union and electrical slip ring technologies into a single complete solution for fluid, power, signal, and data transfer. The company also incorporates Fiber Optic Rotary Joint (FORJ) technology for transmitting large amounts of data via optical signals.
