Company History

  • 2006

    Sapphire Technologies’ parent company Calnetix Technologies gained experience with energy recovery starting in 2006 when it acquired Turbogenix, a small start-up company capable of recovering heat from a variety of sources to produce usable electric power.

  • 2009

    An integrated high-speed turbine expander and high-efficiency generator was first used in Calnetix’s subsidiary Access Energy’s Organic Rankine Cycle system, which was developed for the purpose of recovering heat from internal combustion engines and biomass boilers.

  • 2017

    Access Energy achieved an install base of over 400 units worldwide with millions of hours of operation.

  • 2018

    Calnetix secured a 300 kW turboexpander generator development program for a natural gas pressure let down station from Baker Hughes.

  • 2019

    The turboexpander generator developed for Baker Hughes was installed in Italy. A purchase order was secured for the installation of FreeSpin® In-line Turboexpanders at major natural gas utility in Asia.

  • 2020

    The gas pressure letdown application installations served as a basis for the formation of Sapphire Technologies.

Our Facility

Sapphire Technologies is co-located with parent company Calnetix Technologies on a seven-acre campus in Cerritos, California.

Sapphire has a state-of-the-art test facility for its FreeSpin® In-line Turboexpander energy recovery systems. Test cells are utilized to verify and validate the operating conditions of the FreeSpin® system. The validation tests at the facility include magnetic bearing load testing, full-speed operation of the generator and testing of the backup bearings at different design speeds. The engineers at Sapphire use bench testing to validate individual components and functionally test full assemblies. Further testing is done at the system level to ensure conformance to system level requirements.

Intellectual Property

Sapphire Technologies has been granted all background intellectual property for its FreeSpin® In-line Turboexpanders by Calnetix Technologies. This includes permanent magnet machines, variable speed drives, magnetic bearings and system level controls. All patents have been developed internally and are protected and controlled in-house. Sapphire is filing its own application related patents for FreeSpin’s use in hydrogen and natural gas applications.
